Temperature measurement Thermostats... Nice new toy.

[rustic]

If you want to buy a cheap handheld Non Contact Thermometer, then look no further...

On offer from Maplin, at £19.99, it showed my engine block at 77.4 C, so maybe I need a warmer stat. Ok accuracy +/- 2% plus 2 degrees, not brilliant, but being able to see changes in temperature is great.

My neighbour bought one first, so he could see which wall in his kitchen was the coldest, to see why the kitchen was always cold....


You can measure radiator temperatures, hot spots, cold spots as you can leave it switched on and move it a long a pipe, hub, axle and you can see the hot spots, guess you could use it on a gas cylinder as it has a lazer pointer so you can see where the temperatre changes, ie at the level of compressed gas.

Tried it on my brake disks, brake drums to check if brakes are binding.....

Measures the ground temperature, to check for ice......

Check the fridge contents temperature, brilliant..

If you reserve it on line, from your local store and if you quote this code when you collect the item and pay at the check out, you will get a free Maplin catalogue, worth £3.99 Big Deal, but a usefull reference item.

Code: RasCat

yes they are great as a rough idea on temperature, but not very accurate, unless the item you aim at is mat black, the problem is that IR irradiates at different levels depending on the material, so bright copper pipe will give a different reading to the same pipe with a dab of mat black paint on it (ignoring the insulating effect of the paint) but if you need to know the difference in temp between in pipe and out pipe of a radiator then yes very accurate re the difference but not of the actual temp, I have had one of these for more than ten years (cost over £200.00 at the time) but as a heating engineer paid for itself many times, Rick

According to the info, it uses ultrasonic, which I wouldn't have thought was right, as I expected infra red as well.:nenau

I remember the black body radiation, that matt black gives off more heat than silvered objects, but also absorbs more heat than silvered objects.

Hence computer heat sinks are black and old metal kettles are chromed.

Rustic you are right there, ultrasonic no way, it is defo infrared, lovely toys, Rick
