The Black & Decker Thermal Leak Detector helps you increase the efficiency of your home's insulation by finding weak areas that can lead to higher heating and cooling bills. You'll instantly identify problem areas around drafty windows and doors, and uncover hidden leaks and insulation "soft spots" around your home. Check windows, ducts, and walls with the thermal reference light that indicates hot and cold spots. You can even use the detector to diagnose engine misfires or check your refrigerator and freezer settings.

Black & Decker TLD100 Thermal Leak Detector

 5.0 out of 5 stars This meter is a dandy, especially if you're tech-nerd
By G. Stelzenmuller
Even if you are an unfortunate non-tech "regular" person. Man, what fun to aim and read this dandy little hand-held temperature detector. This device reads the temperature difference between a "reference point" and wherever else it is pointed around the house (probably only from the inside!). The trick here is to see where temperatures are somewhat lower than the reference point. The reference point, by the way, should be some wall or surface that you suspect is kind of the "average" temperature of the house. This means that the home owner can more easily track down places where cold outdoor air could be leaking in, or where the insulation does not stop heat losses like they should. Leaks almost certainly will be the big heat loss killers (or heat gain into an air conditioned space inside in the summer).

Once leaks and losses are narrowed down, then a trip to the hardware store to get some caulk, weather stripping, and limited insulation for hopefully less than one hundred dollars will go a long way to spending less on heating and cooling.

A couple notes on this instrument:
- This can read temperature differences up to about 300 degrees Fahrenheit, so there is plenty of range. This can be important for finding dangerous HOT spots around the house, and having little to do with energy savings: heating or stove problems hidden from view, electrical shorts behind the wall, etc.
- You can set the infrared beam to indicate temperature differences of either 1 degree, 5 degrees, or 10 degrees, giving you a good choice of the sensitivity you are inspecting; and the differences are visual - a green spot for temperature within allowed limits, red spot for too hot, and blue spot for cold beyond the limited tested.
- Windows and transparent surfaces (and probably shiny surfaces) will not test well with the instrument. Not a big deal.

This tool is an excellent buy.
