It's a bit of an estimation really, but it holds up as a decent estimate in practice. You base the estimation on the flow rate of the regulator. Most detectors use a 0.5lpm regulator, and on average a calibration takes about 2 minutes of gas, so about 1 calibration per liter. That'll vary based on the gas detector and the flow rate of the regulator you use. You also need to calculate that the bottom 75 PSI or so of the cylinder won't be useable because it doesn't have enough pressure behind it to flow properly. Worked out, this gets you to: 34L - Est 30 calibrations 58L - Est 50 calibrations 116L - Est 100 calibrations MSA uses a 0.25lpm regulator which should grant you about double the calibrations, but due to their LEL sensor switching beads internally after each calibration you should really calibrate it twice to ensure both beads internally are calibrated, per MSA's tech support. Hope that helps!

@Idealcalibrations thank you so much for this detailed response. It would really help me solve the issue i am currently facing

@@techvase Glad it helps! What's the issue you're facing?

@@Idealcalibrations thank you for asking. I have been tasked with carrying out the calibration of gas detectors in a fertilizer production plant. Being my first time with some of these gas detectors like detcon ir-700 and Honeywell XCD series, i do not really understand how to go about it. If you can provide your email for a more comprehensive conversation, i would really appreciate it.

@@techvase Honeywell XCD is pretty easy, depending on the gas. Detcon I'm assuming is either an LEL or VOL CH4 detector and shouldn't be too difficult as well.

Hello, that's not a monitor I've seen before. Can you send a photo of the unit and sensor? Thanks

Hey there, it sounds like it's time to replace the sensor that is showing an error. Which sensor is showing the error?

Hey there not sure what you mean here

Hey Amal, unfortunately we've never seen an Airchek Touch on our end, and it looks like they're an air sampling pump, not a true gas detector, so it's not something we're likely to have sent in to us (we only work on gas detection devices and pumps currently). That said, I was able to find this video for you, not sure if it's the proper model but it may be close enough for you: kzbin.info/www/bejne/l4K3o4GOicifZ6M

@@BhaskarRoy-f1p hey there, sounds like you're using a fixed flow regulator, does it have an on/off knob? If so, make sure the valve is open the entire time, don't hook it till the unit till it is open. If I were you I'd recommend using a demand flow regulator instead

@@Idealcalibrations Yes, on/off knob with a regulator. Do I have keep it fully open? I just left it like partially open. Kindly advise.

@@BhaskarRoy-f1p fully open, it's not a flow adjust valve, you want it either all on it all off

ISC Tango TX1 is a portable single gas detector. They measure gases in the air like Carbon Monoxide, Hydrogen Sulfide, or other toxic gases. Each type of TX1 has a set of sensors inside that are keyed to that particular gas and change their electrical output accordingly if there's a toxic gas in the air. Hope that helps!

@@TecraTube for sure! Go to idealcalibrations.com/ and click calibration and repair

@@Idealcalibrations thank you

If you have a PID sensor you'll need an additional cylinder (idealcalibrations.com/Isobutylene-C4H8-calibration-gas/?sku=103DST-0038-48) to calibrate. Once you finish the 4-gas calibration it will enter the PID calibration and ask you for the Isobutylene gas. Just repeat the last step from the 4-gas calibration and you'll be good to go. You have enough time to quickly remove your tubing from the monitor, then the regulator from the cylinder, and finally to screw the regulator into the Iso cylinder and reattach your tubing. If you don't detach the tubing from the gas detector you can sometimes have errors on the pump so keep that in mind.

@@Joe_Heinz_BJJ hey Joe, cylinder and regulator are in stock on our website, www.idealcalibrations.com

Hello, if you visit our website at idealcalibrations.com you can put in a request and we'll get a quote sent over to you!

For toxic/LEL it's going to be the long number on the bottom of the sensor, usually on a white sticker. For the O2 it's the long number on the label on the side.

Hello! This answer is a long one, so I'm going to link a blog post I made on the topic if you want more info: idealcalibrations.com/blog/why-does-calibration-gas-expire-fade/ Essentially components like Hydrogen Sulfide are reactive and can interact with things like the cylinder wall, valve, or oxygen in the cylinder over time. A cylinder that you bought at 25ppm from the day it arrived may be down to 23ppm or lower by the time the cylinder expires. This will screw up your calibrations and you'll either start seeing false positives or if the H2S fades too low you'll start seeing failed calibrations. Generally when a sensor has an H2S issue the first thing we double check is the calgas that was used to calibrate it. Some gases, like Ammonia or Chlorine, are far more reactive than others, so you'll see their warranty and expected life as much lower than other cylinders that have H2S or SO2 in them. Hope that helps!

None that I would trust if using a gas detector daily. What gas are you looking at? Unless it's something seriously exotic you should be getting way more than 6 months out of a cylinder

haha I'm glad it helped! It's always the problem children that are the most instructive

Hey Rathan, did you wait an hour or so after installation to test? If so and it still failed, it's either the board has gone bad in that slot or you got a dud O2 sensor. If you got a dud I would send it back and get a warranty replacement. Unfortunately like 2% of them fail coming out of the factory. Make sure you've purchased from a reputable supplier, I've seen a good number of these being sold through Amazon and the like coming out of China with bad quality and fake labels.

Hello, sorry for the late reply, but do you have those sensors installed on the unit? If not you'll need to purchase them, I'd recommend sending it in to a service shop to have it done if you have one nearby, or you can always send it to us if you're in the States.

It's normal for there to be a smell but there doesn't necessarily need to be one. Sometimes your nose gets used to it and you can't smell it so well.

With NH3 sometimes it's a good idea to run some gas over the sensor first to wake it up. This can also show you if the gas or the sensor are dead. I'd also try and keep the tubing length as short as humanly possible. 2-3 inches of tubing max. Make sure to check the expiration on your gas as well. If it's expired you'll need new gas. NH3 sensors aren't the most robust either, so they may just randomly fail as well. Try and keep track of your sensor warranty dates to save yourself some money.

Great question! Generally it isn't. Calibration gas can be used as bump gas, but bump gas can't be used as calibration gas as it isn't accurate enough. Bump gas is usually just a high concentration that has less accuracy and is used to set off the alarms each day.

Hey Martin, what does your clock say? Often when there's a problem with the clock it won't save the calibration properly because the date is off.

@@Idealcalibrations I didn't pay attention to the clock, I will check it today and get back to you.

​@@IdealcalibrationsI just checked the clock is okay.

Hello, this sounds like it might be a problem with your oxygen sensor or potentially your settings. Is the oxygen sensor reading properly in room air? Should be 20.9% when you look at the display

Thank you so much for your quick response. My suspicion is that it may not be configured to allow field calibrations. The oxygen sensor is reading at 20.9, which seems unusual. Do you have any videos demonstrating how to connect to Fleet Manager and whether there is an administrator password? Thank you!@@Idealcalibrations

@@marcelolandeiro1153 If you have the little blue USB adapter and Fleet Manager downloaded, you just need to click on Configure and then use the password "admin" with no quotes and it should let you in.

Hello, my bet would be that something is going wrong during Zero. Is the oxygen sensor reading properly? Alternatively, it could be the configuration on the monitor. You need to make sure it is set to allow for field calibrations. It comes this way from the factory, but someone may have changed it. Check it out in the Fleet Manager software

I feel you, it's always hard to change from one brand to another when you like them. Hopefully the Honeywells grow on you a bit. They are easy to use at least, but I much prefer the button setup on the MSAs. Thanks for the comment and get those things calibrated!

Hey there, sorry for the late reply, but what's your oxygen sensor at? My bet if it's in constant alarm is that the O2 sensor went down.

Hello, to change the date and time on this monitor you'll need to use the BW USB connector in conjunction with their free Fleetmanager II software. Here's a link to the USB adapter - idealcalibrations.com/ir-connectivity-kit-with-fleet-manager-ii-software/

Hey there, you've read it correctly on the dust filter. Fibrous dust filter has a habit of picking up your Cl2 and throwing off calibrations or low level readings. If you're running a unit with a Cl2 sensor, just use the thing water stop filter (internal on unit) instead. Make sure you're also using the reactive tubing instead of the standard or it'll suck up your gas. Finally make sure when you cal the Cl2 sensor you're using a dedicated stainless steel regulator that isn't used on other cylinders (store it not attached to the cylinder as well) and use the shortest possible length of tubing you can get away with (1-2 inches). There's no set interval on changing, but I use the following guidelines: 1. Is the filter visibly dirty (not just discolored a bit) 2. Are you having a calibration error 3. Is your monitor failing pump block test or having pump issues. Any of the above and I would change the filter. You should be changing filters in this order of frequency/priority: 1. Water stop filter inside the probe (cheapest) 2. Fibrous dust filter (middle priced) 3. Moisture membrane in monitor (most expensive) Hope that helps!

Hey Samuel, Best bet would be to fix an O2 sensor fail is to just replace the oxygen sensor (found here if you need one - idealcalibrations.com/sensor-bw-gasalertmicroclip-x3-o2-sensor/). If your old sensor leaked any electrolytic fluid on your O2 board you may need to replace that as well (part for that here - idealcalibrations.com/bw-gasalertmicroclip-xl-xt-flex-printed-circuit-board/). Once you've installed the new sensor let the unit sit for 45 minutes or so to stabilize. Then zero and calibrate the X3 and you should be all set. Hope that helps, let me know if you have any further questions!
