Good value easy to use. Meet expectations. Read more

Muy fácil de usar, apuntar y disparar. Parece fiable, y con mirar el color del foco ya se sabe si la temperatura es inferior o superior, sin tener que mirar la pantalla. Read more

great value for the price. Measures the temp where you put the beam...then tells you as you move the beam if it is getting colder or hotter....or staying the same. You can set the temperature different to 3 settings to widen or narrow your focus as well. great for finding leaks around window and door frames...or even to measure the temperature on walls to see if they forgot to insulate properly behind them.

I hardly need write a good review as others have noted the use of this device, but I will add a few comments. Q: How does this device differ from a standard infra-red thermometer? Why not just use one of those to identify cold bridges, leaks etc? A: you could, but it would be much harder. This device allows you to keep your eye on the area you are measuring and when the beam of light cast upon it changes colour you will know that the temperature measured has varied by half a degree, or 3 degrees, or 5, depending on the switch setting. Moving between these tolerances you can soon build up an accurate picture of where the cold and hot spots are and what might be "false triggers". You COULD do that with a standard digital thermometer, but the rapid changes of 0.1 degree would be hard to keep an eye on and to mentally collate into a picture of varying temperature. This device makes that much easier. That said, it does still require some thought to interpret what you are seeing, combined with altering the tolerance as you work. Thoughts on technique: 1. If you are for example checking a wall for cold spots (e.g. cavity wall bridges) then you need to sweep horizontally across the internal wall with the reference temperature set for that height on the wall. Sweeping up and down will OF COURSE show a marked (and irrelevant) change in the temperature of the wall because the top of the wall will be warmer than the foot due to hot air in your room rising. 2. When tracking draughts, one needs to hone in on them, keeping in mind that a draught, say along the floor, will cool the floor for a distance. Thus a reading of a cold floor at spot A might not indicate any problem with the floor itself, but that cold air is flowing over it from location B (the hole) a few feet or inches away. The direction of flow of the cold air can be surprising and counter intuitive, especially if you have an open fire, stove or blown air system in your house which can push and pull the draught in odd ways. 3. Moving between the tolerances of 0.5 and 3 degrees is important. Too fine a tolerance and you will get distractingly false colour changes i.e. "false positives". Using the 3 deg tolerance might miss something. I would like to have seen a setting on the machine for 2 deg. That small change is important. For example: in my house, the areas around the windows have micro-leaks. This seems to cause a cooling close to the air leak of about 2 deg in winter. If I set the tolerance to 3 deg, I will miss that leak spot entirely. If I set it to 0.5 it will pick it up, but the colour indicator will be changing rapidly anyway as I move across areas that are not really a problem. The solution seems to be to move between the two tolerances while repeatedly scanning the area and take note of the pattern of change until you can hone in on the causal area, finally confirming the coldest spot (the leak) with the finest setting. Q: can you use this as a standard thermometer? A: only up to 150 deg C. So it's no use for measuring the oven temp or the jam pot. Read more
