How to Clean a Micron Gauge

[@g.martinez2871]

I just use tequila. I always have some in my van for in between service calls anyway.

[@speckulator7516]

I like the way you think G!

[@MrDjonks86]

Can you also show how to clean tru blu hoses if they get contaminated by oil.

[@hvacguru-Kansas]

Rubbing Alcohol worked great on a malfunctioning pressure transducer for EXV. Just FYI. Another reason to have some on your truck. I'm a BluVac fan as well, by the way.

[@TropicalRegicide]

That's good to know!

[@Honestandtruth007]

Great ideas 😄💡 must have Alcohol/ liquor in the Truck All time 👍

[@paulf1071]

Can you use Isopropyl-Alcohol to clean the inner-lining of hoses too?

[@yinace7]

Yes. You can. Remember to purge it with air compressor

[@paulf1071]

Don't you mean compressed nitrogen?

[@yinace7]

@@paulf1071 yup.. Nitrogen purge much better.

Hi Bryan, So you don't recommend using a spritz of Nitrogen after the 1 or 2 cleaning douches of alcohol to help dry it out, but just let it air dry? Thanks much, Bob

[@amazinggrace831]

CPS recommends denatured alcohol.

My fieldpiece micron gauge doesn't hold and only reaches 690 microns but still it wouldn't hold I tried it directly on my vacuum pump and it reaches 69 and fluctuates back to 179 doesn't stay one place what can cause this does anyone know I cleaned it blow a bit of nitrogen in it but still same thing

[@lyndonlakhansingh]

What about CRC contac cleaner ?

[@maxdoles5806]

I recently had to pull a vacuum on a system I only later realized had insane oil migration. Despite the micron gauge standing upright, the sensor was smothered in oil. I removed the Schrader depressor and poured alcohol in a few times, and it still struggles to read accurately. I'm probably just going to have to get a new micron gauge.

[@phillipwickstrom1593]

My bluvac mini reads oil after 2 uses. I use my old compound vacuum gauge.

[@Barracuda48082]

So this procedure is good for digital gauge manifold too?? ei..Testo 550, higher or Fieldpiece

[@MuthaFukinLongboard]

Yes

[@omsingharjit]

How this sensor works ?

[@jamminwrenches860]

It has a tiny heater and it measures how quickly that tiny amount of heat dissipates. The less atoms present to get excited by the calibrated heat source the slower the heat dissipates and therefore we can get a measurement. Pretty ingenious if you ask me. The tiny heater gets covered in oil and throws the whole thing out of whack.

Hey guys can you use this trick on a Fieldpiece SM480V

[@hueman809]

Rubbing alcohol leaves a residue, wouldn't an electronics cleaner work better?

[@HVACS]

That will also work fine, I've had no issues with alcohol

[@itsnotfar]

Isopropyl for the gauge and alcohol for the operator, got it. Oh, it doesn't go in the eyes.

Way cheaper to just get a ball valve instead of using a second CRT

You talk too damn much
