Black & Decker THERMAL LEAK DETECTOR (Conserve Cooling Atmosphere) cool

Nice product

This is a great detector, with changing lifestyles a must have home instrument

I wanted a remote-measuring thermometer for checking my home for hot spots (in summer) or cool spots (in winter). This one is great! It couldn't be simpler to use, and it's very accurate. It projects a green, red or blue spot onto the wall or other surface being measured. The green spot represents the baseline temperature of a wall or other surface measured when the unit is powered on. The spot turns to red when scanning a surface that is hotter than the baseline temp, or blue when scanning a surface cooler than the baseline temp. The colored spot makes it really quick and easy to scan for hot and cold areas, since you don't need to pay close attention to the actual temperature reading until you find a zone of interest. At first I thought that the colored spot might just be a gimmick, but, in practice, I have found it to be a really useful feature. My background is in science and engineering, so I appreciate instruments that are accurate and work well. I checked this thermometer against several others that I know are accurate and it consistently agrees with the others +/- 2 degrees or better. This is within the specs for this device, and pretty good for under $30. Be aware though, that this unit remotely measures the temperature of surfaces, so it is not a good choice for medical use, for cooking and for other jobs where you need to measure internal temperatures. That said, it will measure the temperature of your skin pretty accurately. It will not accurately measure the temperature of shiny or transparent surfaces, but you can stick a piece of masking tape or duct tape on the surface and measure that. It's so sensitive that it will easily measure the residual heat left by my bare foot standing on a cool wood floor. Leave your foot in place for a minute or so, so that the temperature of the floor is increased by your warm foot. Move your foot away, then measure the temperature at the spot where your foot was, and the surrounding floor. The red LED light will light up when the thermometer is aimed at the outline of your foot, but will turn to green for the surrounding area. (Note: this probably will not work for concrete floors, since they will not warm up enough). You start by aiming the unit at a reference surface, such as a wall, to establish a baseline temperature. (Note: a switch in the battery compartment sets either Farenheit or Celsius for the readings) Then you can select one of three ranges: +/- 1F*, +/- 5F* or +/- 10F*. (.5, 3.0, 5.5 C) I like to start out with 10F*, since that will quickly let you zero in on any serious hot or cold spots. Spend your time fixing those spots first, and you'll get the best bang for your buck. After those spots are fixed, or if you don't find any in the ten-degree range, then move to the 5-degree range and repeat. Aside from its real value in finding and fixing thermal leaks, this thing is a heck of a lot of fun just to play with. My grandkids had fun searching for hot and cold things around the house. On the 5-degree setting, you'll find that just about anything that runs on electricity and stays on all the time (clocks, power cubes, etc.) will turn the LED to red. A/C ducts will turn the LED to blue if cool air is coming out.

Esperienza ottima. Perfetto per individuare spifferi dagli infissi, con una buona precisione e di facile utilizzo. Segnala con cambiamenti di colore del fascio luminoso la differenza di temperatura sulle superfici rispetto a quella di riferimento. Buon rapporto qualità/prezzo. Imballaggio impeccabile.

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.

très bien fonctionne bien
