Thermometer Update
Dec 31, 2019 07:31:40 #
I posted a few days ago about a laser thermometer I received from Amazon. The battery was dead, and I didn't have a 9v to use. Amazon sent me a replacement, and it works fine. One thing I thought was interesting - this battery was wrapped in plastic, unlike the first (dead) one I received. The thermometer registers to 1022° F, but the fire in my wood stove was beyond that. Wood burns at over 1,100°. The stove itself measured 600°.
The handle is rather small, so fitting the battery and connector takes some fiddling, but it works fine once it's closed. The price has gone up $3.00 since I ordered it on 122/21.

It can measure temperature from a distance, and it's good for comparing different areas/components. If one brake caliper is much hotter than the other, that indicates trouble. It's also good for checking wall temperatures in the winter. Where do I have to add more insulation. I found that my double glazed windows were warmer than the adjacent wall - surprising.
Also, because it's gimmicky.

If you read the description, you’ll find that it is actually an infrared thermometer the laser only shows you where the reading is being taken

What you point it at makes a difference. You get the best readings off of a black surface. Try this test. Find a copper hot water pipe. Paint a couple inches black. With the hot water flowing, take a reading on the black painted section, then an adjacent bare copper section. Point proved.

... I use one of these to check the surface temp of my BBQ grill cast iron Plancha before I put a Steak or Burger on to the grill. I want the surface temp to be over 500 degrees so the meat will sear and also have a nice crust on it while keeping the inside nice and pink. In the house, I use it to check pan temps on the cookstove to ensure they are hot enough.
...Also, it's fun to check the temp of the surface of my pool during the summer as the water gets bath temp easily!! Arizona Summers are fun! ...Not!

A good tool for measuring temps coming out of overhead vents that are too high otherwise (think AC repair)

Well, the last reason is why I suddenly need to have one!

Check your breaker box to, you will see if one breaker is pulling to much or has an issue. Our business insurance inspector checked all of ours on his last visit. I ended up changing two out after he left.

I've had one for many years, very handy. Used to use it to see which cylinder wasn't firing on aircraft engine.
Great for taking temp at places one can't reach easily.

Well, my cat absolutely *loves* it! And the batteries are easier to get than those tiny fiddly things that are typically used in laser pointers...
Incidentally, mine does go through batteries surprisingly quickly... You would think a 9-volt would last for ever in there, but of course we don't know how much power it is using for the whole infra-red thing.

Used mine to diagnose a car engine cooling problem. Checked engine outlet temp, radiator inlet/outlet temps; at idle and at 2000 rpm. Found radiator flow problem--insuffcient at low speeds. Replaced radiator.
Great device. And yes, you have to focus on "black" surfaces--with black meaning anything but bare metal. The reason is emissivity from surfaces. Its low from bare metal, almost same (0.9+) for other surfaces except white.

Also handy for troubleshooting older electronics.
You can check the temp. of a component without touching and risking a nasty shock.
