FLIR TG56 Spot Thermal Camera

I purchased this product and it arrived the same day! :-)I used a Calex FTK 35 radiation source (fixed at 35 C) to determine accuracy and here are the results:Average temperature (20 readings, from 6 inches away):Average/ mean: 35.13 CStd. deviation: 0.53 CMinimum: 34.1 CMaximum: 36.1 CMaximum Likelihood, 95% Confidence Interval:Lower: 34.9 CUpper: 35.4 CVery pleased with the results.Only hic-up is that the trigger needs to be pressed about 3 seconds to activate unit, and the default dwell/ ON time is 5 seconds (but this can be changed by going into the OK menu (press about 2 sec) and change to either 10 sec or 20 sec.)Also happy with the option to change emissivity value to accommodate different materials.Ergonomics are also very good, typical of other FLIR products.

This review is for the TG130 model (be sure to note several different models are reviewed on this page!). At first I was kinda disappointed with the unit, but after playing around with it a few times and getting the hang of it I'm actually really pleased with it. It has limitations for sure, but for the price you won't find another unit that comes anywhere close to it and in many ways it out performs much more expensive units.The directions in the manual pretty much consist of "Aim the camera at something and read the temperature." However it very helpfully says this in 22 different languages (literally). Although NOT mentioned in the manual, if you open the battery compartment and remove the batteries you'll see a very very tiny switch which you can use to change the readout from Celsius to Fahrenheit.The thermal imaging has limited functionality, which may or may not matter for your application. The colors on the screen are always relative, so the image shows temperature differences but the colors are arbitrary. Red might be 45 degrees in one application and 95 degrees in another. And the wider the range of temperatures on the screen, the less detail you get of the temperature variation-- this could be especially relevant to certain outdoor uses. Depends on what you want to do. You can kinda work around it by playing with the distance between the object and camera. I've also noticed the angle you hold the camera can make a big difference-- sometimes tilting the camera just a tad more downwards can give a more detailed image-- I'm not sure why.The temperature reading is of the central point on the screen and is impressively accurate to a fraction of a degree. But like ALL thermal imagers the accuracy of the reading can be affected by external factors like wind or draft, sunlight, or any variation in material or thickness between the heat source and surface. Obviously ANY thermal imager can only read the surface temp, which often isn't the same temperature as the heat source itself.Note this unit can't save or transfer images. If you press the trigger it'll freeze the image, but once you click the trigger again the image is gone. More expensive units can save the images on an SD card or internal memory. You also can't change the color scale, adjust the measured temperature range, or otherwise change the image or measurement. But the resolution is very good in that you can obviously tell in the image what the object you're looking at is. I tried another cheap thermal imager and all the images just looked like blobs. The distance this can pick up is very impressive - I've used it to find my horses in the dark in a 20 acre pasture surrounded by a treeline and it's able to show me where they are, even on the other side of the pasture. Point it at the horizon and slowly turn it straight up and you can watch how the temperature falls as you get further from the earth, which is kinda amazing.The screen is small but adequate, but really bad for glare if outside. The buttons feel tight and solid. The unit itself is a little cheap feeling (not horrible but there's no "heft" or solid, weighty feel) and you'll definitely want some kind of protective case. I doubt it'd hold up to being left lose in a bag that gets tossed around. It comes with 3 AAA batteries and if you use the imager a lot you should carry extra batteries with you - there's no read-out of the remaining battery power.Oh, and I was also a little perturbed to discover a $14 tax added to the total when I checked out (if it matters, I have Prime). I don't know if it applies to everyone or has something to do with where I live, but there was no such charge when I ordered the Prime-Perfect unit (which was complete garbage by the way). Anyone ordering this should pay careful attention when they check out, and consider if they're willing to pay an additional $14 for this item. It's worth it but it was an unwelcome surprise and unusual in my experience with Amazon.

Bought this FLIR TG54 Spot Infrared Thermometer to replace my broken Fluke 62 Mini and was really surprised by how much more powerful in terms of performance the FLIR TG54 is when compared to the Fluke 62 Mini.First off, the TG54 is wonderfully compact and sleek in design, with weight distribution right down the center of the device. No tipping forward or backward when holding and using the device. The included additional function of a forward facing LED light is a very convenient for engaging in thermal measurements in poorly lit area, a very nice design touch indeed.The TG54 actually uses a anti-reflection coated IR lens while run-of-the-mill infrared thermometers of this price class will use plastic Fresnel lens. This give this small unit an absurdly high spot to distance ratio of 24:1 (1 inch circle when 2 feet away from target). This spot to distance ratio is only available in higher end models of other manufacturer costing multiples of the cost of the FLIR TG54. Hitting small measurement areas will never be difficult again. Do note that the spot will not reduce to any smaller than the actual front aperture of the TG54 of 0.75 inch as a rule of thumb (i.e. 0.75 inch spot when 18 inches away from target is the limit, any nearest will still be 0.75 inch spot)The laser guide on the TG54 is actually calibrated and aligned to be parallel to the optical axis of the IR lens. This means that where the laser touches, you can estimate the optical center of measurement to be about 0.75 inch below the laser dot. Totally takes the guess work out of IR temperature measurements.The TG54 also features adjustable emissivity settings, allowing measuring highly reflective items (i.e. stainless steel pipes, chrome plated metal items, polished drive shafts, etc.) a breeze. You may want to print out a small emissivity table and attached it to the lanyard point on the TG54 for a convenient guide to the emissivity setting of the material you are measuring.One small gripe with the unit to date is that there is a significant pause before the unit comes alive when the measure trigger is pulled when the unit is on cold shutdown mode (i.e. screen dark). But when the screen is still on, measurement mode is triggered without delay and measurement update fast enough to allow for you to scan an area quickly to determine the highest temperature observed.Lastly, the TG54 runs off 3 x AAA batteries which is easy to find and much more long lasting than 9V batteries that most other IR thermometers requires. Substituting the alkaline AAA to typical Ni-MH rechargeable batteries does not detrimentally affect performance.Overall one of the best pieces of measurement hardware I have acquired to date, will not hesitate to purchase any product from FLIR!

Ich habe dieses Gerät eingeschaltet und ohne besondere Kenntnisse einfach losgelegt. In unserem recht großen Haus (vier Wohnheiten auf zwei Etagen) gab es Probleme mit der Heizung, ständiger Druckverlust. Auf dem Display sieht man den Raum vor sich als Wärmebild, wobei die jeweils wärmsten Stellen in gelb oder hellrot dargestellt werden, die kältesten in blau / schwarz. Entscheidend ist also nicht die Temperatur selbst, sondern es werden die Temperaturunterschiede sichtbar gemacht! Die tatsächliche Temperatur der untersuchten Oberfläche wird im Display jedoch angezeigt. Diesen Wert kann man kurzfristig auf dem Display einfrieren, man kann bei diesem Modell aber keine Bilder speichern. Wichtig: Ein heißes Objekt (z.B. Heizung) glüht im Display förmlich, rundherum nehmen die Farben dann ab. Eine undichte Stelle fällt sofort auf, weil sich dort ein Farbsee bildet von hellgelb nach blau. Obwohl die Heizungsrohre in 25 cm Tiefe unter dem Boden verliefen, konnte ich doch das Leck finden, da sich um die Leckage das ausgetretene warme Heizungswasser sammelte und damit für die Kamera erkennbar war. Ein Feuchtigkeitsmeßgerät hingegen scheiterte (dringt nur bis 4 cm tief in den Boden!) und die Hand spürte keinen Wärmeunterschied (Laminat/Estrich dämmten zu sehr). Die wegen der Versicherung notwendige professionelle Firma bestätigte meine Ortung. Als nächstes werde ich das Gerät verwenden, um Wärmebrücken aufzuspüren (Heizkosten / Schimmel). Ich kann dieses Gerät jedem Hausbesitzer empfehlen. PS.: Beim Einsatz künstliche Lichtquellen ausschalten / verdunkeln, ferner nicht zu nahe rangehen, 2-3 m Abstand sind gut. Die Farbverteilung ändert sich schlagartig, wenn man einen Finger vor das Visier bringt, das kann durchaus mal sinnvoll sein (ausprobieren!) Und zu guter letzt: Im Dunkeln ist nicht immer gut munkeln - das Gerät sieht auch auf 20 Metern durch jeden Busch ;-)

2eme produit de la marque acheté.Des tests ont été effectués et jusqu’à 3 degrés d’écart entre les deux thermomètres dans les mêmes conditions de test.Produit renvoyé.
