Description of Black & Decker TLD100 Thermal Leak Detector
The Black & Decker thermal leak detector helps you increase the efficiency of your home's insulation by finding leaky 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. |
 The TLD100 lets you identify weak spots that can lead to high energy bills. View larger. |
The thermal leak detector makes it easy to monitor your home's energy efficiency by finding areas that let heat out and cold air in. Simply set the detector's temperature tolerances to one, five, or 10 degrees and scan the light across the area you want to inspect. The light will change to red for warmer spots and blue for cooler spots to detect air leaks in both warm and cool weather. The detector also displays temperatures in either Fahrenheit or Celsius on the LCD screen. Check for drafts or leaks around your fireplace, recessed lighting, electrical outlets, along floor molding, or any place that may have improper seals, caulking, or seams that aren't immediately visible. An included booklet gives you tips and instructions on how to seal leaks and improve insulation.
Cut Energy Bills and Improve Your Home's Efficiency
Sealing the leaks and improving insulation in your home can help you save as much as 20 percent on your heating and cooling bills. An efficient, greener home will stay cooler in summer and warmer in winter, increasing its resale value.
Multiple Uses to Handle Uncommon Tasks
Use the thermal leak detector to check your refrigerator and freezer temperatures and efficiency. Diagnose engine problems related to overheating or coolant leaks to avoid costly repairs and mechanic bills down the road. The thermal leak detector can also check the operation of your HVAC system, so you can perform preventative maintenance as needed.
The Black & Decker thermal leak detector is covered by a two-year warranty.

Tools and Hardware Reviews of Black & Decker TLD100 Thermal Leak Detector
Customer Review: Does what it claims...
Summary: 5 Stars
I've used thermal guns before but this 3 color light indicator is way cool. It makes checking temp delta's very quick. With the old gun (with laser pointer), it was, point at the area you wanted to test and then look at the meter, repoint the meter to a new location and look at the meter again. With this TLD100, it was just move the light around the area you are checking and the only time you have to actually look at the meter is when the color changes. It completely eliminates this looking back and forth at the target, then the meter, then the target, then the meter,...
A comparison would be the difference between using a box end wrench or a rachet wrench to remove bolts. It makes the process much simpler and faster.
I bought my unit at the wrong time of year when the outside temp was, at maximum, only 30 degrees different then the inside temp so even though I found some leaks, they were minor. My house is about 40 years old and since I bought it a few years ago, I installed storm doors and had added insulation to the attic. All the windows and doors are relatively new and from what I can tell, this house is relatively tight. Even though I didn't find any major problems, it's gives a certain peace of mind to know that everything is okay. This summer when the temps hit the 90's, I'll retest.
The bottom line is that for home use and price, this is a very good meter. As some posters have pointed out, there are more accurate meters available and IR camera's that have far more versitility, but for what they cost, it would be much cheaper to not fix your leaks and just pay for the extra energy costs.
Addendum:
I've owned this product for a while now. When I first got it, it took under a minute to figure out how to use it. The concept behind it is very simple and very well done. At first, to my chagrin, my house seemed very tight and I found no hot or cold spots of any significance. I almost felt like I wasted my money, but there is a certain amount of consolation knowing that everything is in order.
Recently, I bought a whole house fan, but my attic access was too small to get it into the attic, so I enlarged the opening. I knew that I would have to insulate the cover to the new opening, but before I got around to it I used this product to see what to expect. It was a warm day and I had the air on at about 77 degrees. When I pointed the meter at the new attic cover, it was reading almost 100 degrees. What that meant was that I had a radiating surface of about 7 square feet at 23 degrees over the interior of the house temperature. Looking toward the future when the winter would come, I could have a temperature differential of over 100 degrees during very cold days. In the summer when the temperature gets into the mid 90's or more, my attic temp exceeds 140 degrees. This would give me a temperature differential of over 65 degrees.
I figure that this knowledge alone would pay for the meter in short order.
Anyway, I really like having this meter and contrary to what some posters have said about it's accuracy, it's the delta (temp difference) that is the most important thing to be concerned about in this case.
