Review on 🌡️ Infrared Thermometer Gun -58℉~1022℉ - Non-Contact Temperature Gun with LCD Display for Cooking/BBQ/Refrigerator by Robert Hoge

Nice colour, nice color LED screen but that's it. I give him one star for that. It takes 3 to 5 minutes to capture the ambient temperature when moving from inside to outside for example. As for HVAC, I couldn't get a decent reading from the vent. always 5 to 6 degrees. I use my trusty meat thermometer, it's fast and accurate. I ordered a UEI PDT650 which has proven accurate and fast on the vents and has also been used in a variety of locations. Even when the laser is aimed at the fridge, it's off by about 5 degrees. The instructions state that you need to set up the radiance configuration for the different objects you want to measure. INDEED! Who has time for that. With a table with all values. If you read the reviews of professionals, it is better to buy a Fluke or Klein Tools model. You get what you pay for.
