Thermocouple Meter Review; Can a $25 thermocouple thermometer be any good?

[@KBorham]

This was so much more than just a Meter review. I didn't know that about the black vs. "shiny" aluminum. I appreciate your knowledge and wisdom sir, cool stuff indeed!

Thank you for your kind comment.

Thank you do much! I was looking to buy one for basic used, this fits my budget perfect!!

[@Jimscoolstuff]

Thank you for your comment.

Great! You CAN get Fluke accuracy for a reasonable price! I liked the bonus information, I learned 2-3 things I have always wondered about! Thanks so much!

[@Jimscoolstuff]

Thanks for your nice comment.

Awesome video, I see many chemistry oriented channels using the infared thermometers and I wonder how much inaccuracy they’re getting. It can’t be that accurate considering it’s often a transparent liquid in a glass reaction vessel being measured.

01:30 i'm sure you thought about the same in regard to the orange thing: It's just a hanger for the shop to hang it on a board and sell it

[@Jimscoolstuff]

I didn't think of that. Thank you for your comment.

@@Jimscoolstuff you are very welcome! Not sure if I'm right, but at least a possibility? Greetings from Austria! Time to go to bed, it's 2am here :-)

You need to put the meter in a temperature controlled environment and test the CJC works properly to prove the meter is good quality. You would not use a thermopile type IR sensor to read aluminum, the emmisivty is not ideal. You need to use a special wave length and probably a cup to block out outside influences.

Need to be able to record temps every hour and be able to record, what would you suggest?

[@Jimscoolstuff]

Watch this video, around 12:00. There are many similar data acquisition systems available. I hope this helps.

Thanks for your explanation. I learned the benefit of using black heatsink.

[@Jimscoolstuff]

Thanks for your comment. Infrared temperature measurement is just about useless.

[@dannythebeerman]

does this dual thermometer have a timer function? Some of the ads show a timer in a pic, but I haven't seen anyone use

[@Jimscoolstuff]

Yes, it automatically turns off after 5 minutes of use.

[@dannythebeerman]

I meant like a stopwatch to monitor rise of temperature over a time period. when the screen turns on, it seems to have lcd's for a timer stopwatch, are you able to use in that manner?

[@Jimscoolstuff]

Not that I am aware of.@@dannythebeerman

[@nivekgad]

Would the unit you tested work with a donut probe for testing temperature on a screen printing dryer?

[@Jimscoolstuff]

Sorry, I don't know what a donut probe is. The meter will work with any standard thermocouple; such as type J, type K etc.

[@fransiscorivaldywetik6125]

Can this tool read temperatures above 1000 degrees Celsius?

[@Jimscoolstuff]

The temperature is limited by the type of thermocouple that is used. A type K thermocouple can be used briefly for temperatures as high as 1200 Deg C. The thermocouple itself must be specially made for these high temperatures. They must be insulated with ceramic materials and sheathed in stainless steel, Inconel, or hasteloy.

[@vincentpernicano3277]

Can you buy longer thermocouples without affecting the measurement?

[@Jimscoolstuff]

Yes. You can buy a roll of thermocouple wire and make a thermocouple any length that you want. Type J thermocouple wire is easy to solder. Type K wire requires a flux for soldering aluminum.

[@vincentpernicano3277]

@@Jimscoolstuff huh okay ..so the resistance of the wire has no impact on the reading or accuracy of the measurement? Do they all have standard connectors…trying to buy this unit and extra connectors so I can make a number of thermocouples

[@Jimscoolstuff]

@@vincentpernicano3277 You can buy connectors and connect them to the thermocouple wire. Black connectors for type J wire or yellow connectors for type K wire. This information is in my other thermocouple video listed in the description.

[@badlordboris9938]

It only has an impact on input impeedance, some temperature meters only allow for approx 22yards 24AWG thermocouple wire, some other allow for much more ​@vincentpernicano3277
