Best portable multichannel thermocouple thermometer

Ovens are pretty cheap on the surplus market if you only want heat. Cooling takes forever without the nitrogen tank.

I've had bad luck with refrigerated test chambers as far as reliability goes, but much less condensation during cold testing than with that nitrogen blaster. I do know someone that swears by Thermotron test chambers. Not to be confuser with the old Thermostream by Temptronic, AKA the cone of silence chamber.

Do you have any experience with those? I have a job coming up requiring monitoring of multiple temperatures. The Extech looks attractive, and the price is right on the money. Thermocouple accuracy is fine.

I'd appreciate any comments you might have.

I don't have that unit but we have a visiting tech for a specific machine that is rented and he swears by it. He has left it at out place a couple times to do long data logs.

I do have some Extech gear myself, one of them has a K-probe and IR probe on it. I would not trust the IR probe so much but the K-probe is very accurate. That meter has been dropped, bagged around and it still working.

I also have an Agilent K-probe meter but at times I question that.

Thanks

I actually bought one of these, and really like it. It's slightly old-school, because it uses full size SD cards, but it works great and is really simple to use--it just takes measurements and logs them to a file until you tell it to stop. Beautiful.
