BLACK DECKER Digital Thermal Leak Detector TLD100

Ordered this & it arrived fast and in perfect order. Went around the up stairs of my house and recorded all the roof temperatures where the wall meets the roof. I set the b&d at 5 degree temperatures difference and as I went around all the rooms it changed color from green ( room temp ) to blue ( loss of room temp by 5 degree ). I recorded all the temperatures and decided to go to roof space and check what was going on.After inspection I seen that the cavity was not closed at the wall plate and the fibre glass insulation wasent covering all the roof in places. So, spent the full day filling cavity with 6 inch fibre glass and making sure that the roof of the bed rooms were all insulated. A real pain in the ass job BUT well worth it the bedrooms are 4-6 degrees warmer and even down stairs is warmer. All for the price of buying 4 rolls of insulation costing 50 Euros. Every house should have one of these and IV just descovered that my front and back door is reading a temperature 13 degrees while the hall and utility where doors are is 22 degree's. So here's my next mission So it's worth every penny, it's cheap,easy to use and accurate. Hope this helps. Edd Ireland.😵

This product s interesting to use to find cold spots etc, but it's quite difficult to "aim". After having used it a few times it was aparent that depending on how far away you are from the surface the sensor could be above or below the coloured dot. Also the unit only tells you the measured surface temperature in relation to the initial reference temp, which in itself is only in relation to ambient temperature, i.e so you can't point at a surface and find out it's actual temperature, so if your sensor was in a room with an ambient temp of 20c and you measured a wall which is 18c the unit will show a refernce temp of -2c. I found it a bit of fun to use but not convinced it helped me to find any real air leaks or cold spots that i could address.

This is much more than a leak detector. Indeed it is wrongly labelled. It is basically an extremely accurate thermometer that tests the temperature of surfaces, including glass!! It identified exactly a cold area on my wood floor that I did not realise I had. Now covered with a large rug, the room is now cosy. The old patio doors were much colder than I realised and replacement is expedited. You can survey your entire house and ID hot and warm spots. For best result do it when the outside temperature is very low; with and without wind. I look forward to using it is out garden and house thermometer at all times of the year This may be the best value and quality product I have ever bought. It makes all non-medical/cooking thermometers redundant, especially as it is more accurate and instantaneous in measurement. And it is fun to use... try checking out the surface of your partner. Thanks to all the five star reviewers who persuaded me to buy this

I moved into a house which we found to be very cold. The Black & Decker TLD100 Thermal Leak Detector has helped me identify the cold spots in the house and I was able to focus on these areas to eliminate the draughts /install insulation etc. I recorded the temperture difference before and after making any changes to ensure my efforts worked. You carry out the checks yourself so there are no expensive tradesmen to pay. Reasonably cheap and easy to operate. The B&D Leak Detector was bought from Ideabright Ltd. (on Amazon) and was received in the North of Scotland within 48 hours (No, the north of Scotland is not an Island and we should not incurr additional postage charges for being on an island, which we did not from Ideabright Ltd. Thank you for this.) In short; a great little product, fun to use, well worth the money in preventing heat loss or just for checking the surface temperatures of your walls, double glazing, finding draughts from damaged door seals etc.

This is a fairly decent item , it does glow red for surfaces beyond hot treshold point and blue for cold spots and green for ambient temp Positive 9v battery lasts ages robust well made easy to use easy to operate comfortable to hold Good accuracy Negative Accuracy not perfect within couple of degress generally from start point Bulky Price not cheap Very basic Good for indication but not great for accurate problem solving

Does the job. Basically point it at a surface to register a temperature in that room and turn on. Then move light around room and it will show lower or higher temperatures than the one you first you set. For example it shows my loft insulation must be missing in some parts of the ceiling as green light turns blue 🥶 Some surrounding windows are colder than others.. must have a draught. All external walls register colder

Didn't even know this technology was available so cheaply until I stumbled across it while looking at loft insulation on Amazon. My front bedroom was always freezing even though the rest of the house was nice and warm. I'd assumed the heat was escaping through the attic and had just planned to buy loads of insulation and double up what was already there. Thought I'd try this gun first in case it wasn't the attic and there was a leak around the window or some insulation missing in the exterior wall. Very simple to use (although I had to go out and buy one of those little oblong batteries, didn't even know anything used them anymore and a shame it doesn't come with one). Set the mean temperature and the deviation then slowly move it around the walls and ceiling and watch the torch change colour as it finds cold or hot spots. What I found was that in one corner of my bedroom ceiling there was a point that was 5 degrees lower than anywhere else! Easily rectified and instead of buying 5 rolls of insulation and doing the whole loft, I just bought one and crammed it into that corner. It was right in the eaves so I couldn't see why that part wasn't as well insulated as the rest, but it's done the trick and that corer in the ceiling is only 1 degree lower than the rest now and it's noticeably warmer. So basically, buying this saved me money and time. Only doesn't get full marks because of lack of battery.

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.

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

Warmtelekken zijn goed op te sporen .met dit handige apparaat. Je meet eerst een referentietemperatuur, waarna je de temperaturen in de omgeving meteen met rood ( warmer), groen (gelijk) of blauw ( kouder) kunt aflezen. Eenvoudige bediening.

Nice product

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.
