#^-@ Black & Decker TLD100 Thermal Leak Detector

This works great as IR (infared) thermometer and as a back up IR imager. You can scan temperature variations over time or over neighboring surfaces. This is not a NIST quality measurement tool, so if you use with that understanding then this will be a great addition for any Green Building professional as well as any home owners that wants to improve home energy efficiency.

This shows where you are wasting electric and since I have a total electric home I need to know where to plug to save my money. I will be sealing more spots after using the leak detector.

This is just for home use, to help battle rising utility bills.

Easy to use, and the color-changing light makes all the difference.

We've been able to precisely address some major leakage and have a much cozier home now.

Now loaning out to others so they can do the same.

This is a nice thing to keep on hand, and we're very glad we got it.

Thank you Black & Decker

A simple thing like having the led spot light change color makes this fast and easy to use. Aim it at a surface of the wall and turn it on. After that, move it to other areas of that wall and it will alert you to cold or hot spots with a color change projected on that area. So in the basement, some of the areas between the joists, at the sill and at the band joist are letting some cold air in. Most are good due to some sealing work I did in the past, but I now see a few need more work. The good ones are green and the ones that need work are lighting up blue. In the future, I will use it in the attic to locate areas that could use some spray foam. You can set it for 1 degree, 5 degrees or a 10 degree change to trigger a color change. This tool is accurate with respect to where the spot is projected and the temperature being taken at that same spot. An easy tool to use and can help save a lot of money by reducing future utility bills.

For the price, this leak detector is an excellent tool for a DIYer looking to improve insulation in their house.

The device is basically an infrared thermometer. The difference with the leak detector is that it compares temperatures, and lights up the wall in different colors based on the comparison.

Here's how it works:
1 - point the detector at a wall that you know is insulated, and turn on the detector
2- upon turning on, the detector measures the temperature of the wall, and remembers that temperature
3- now you move around the room/house, pointing at different parts of the wall, near windows, doors, etc.
4- the detector constantly reads temperature and compares to that initial wall reading
5- A green colored spot is projected onto the wall where you are pointing the detector.... if the temperature differs by a certain amount, the spot turns blue (colder) or red (hotter).
6- a 3-position switch lets you decide whether you want the spot to change color for 1 degree F difference, 5 degrees F difference, or 10 degrees F.

This detector did not just point out the obvious problem spots (like door jams, near windows). You really don't need a detector to figure out those spots. This detector highlighted large differences on the *same wall,* where it turned out that insulation was lacking or had fallen off.

I deducted one star for the accuracy of the temperature reading. I have another infrared thermometer which I know to be accurate, so I compared readings. This leak detector was a few degrees off from the other detector. That said, this leak detector still calculated the correct difference in temperature, which is its main functionality. If you want a very accurate temperature reading, get a dedicated thermometer.

Others have commented on the box size - it seemed pretty appropriately packaged to me. The detector is a rather odd shape, so the box had a fair amount of empty spaces. Nevertheless, the device is packaged well.

Build quality is fine. The whole device is plastic, with a battery door that pops open in the grip. For the price, I have zero complaints with build quality.

In summary, this device is handy and serves its intended purpose very well.
