Curious if anyone has had any experience with these nifty little devices; I’ve been looking into getting one for a while now.
Any suggestions? Preferably under $30.
It’ll mostly be used for grilling, cooking oil, perhaps some other various measurements (charging batteries, checking flashlight body temps).
I have one from Harbor Freight Tools, I think it was $25.
I use it to check the wheel bearing on my boat trailer, works great.
I have a ThermoHAWK 200 that I got for less than $30. I really like it. I use it frequently when prototyping circuits to check the temperature of various components, usually MOSFETs or power controllers.
These small keychain like units have a Distance-to-Spot ratio of 1:1, meaning if I want to measure the temp of something with an area of 1 inch diameter, the unit needs to be one inch away. So to measure a component temp it needs to be right next to the component.
The gun type units with a laser pointer have a distance-to-spot ratio of more like 12:1 so to measure the same 1 inch diameter area it can be 12 inches away. Thus the use of the laser pointer.
I’ve got one of these http://www.ebay.com/itm/200939188072 , no complaints and it seems fairly accurate, though if I were buying again I’d probably get one with adjustable Emissivity
I have one from fasttech https://www.fasttech.com/products/1326105. The temperatures I have checked it at are pretty accurate. The laser doesn’t quite point correctly but not too far off. It’s not a rifle after all.
What about This? cheaper, uses aaa batteries, and adjustable emissivity.
Does anyone know it? I’m thinking of taking one
