Review on Etekcity Infrared Thermometer 1080, Non-Contact Temperature Gun for Cooking & Home Repairs, Digital Laser IR Temp Gauge, Surface Measuring, -58 to 1022℉, -50 to 550℃, Yellow by Jayt Shields

Accuracy not certain. I bought this to test the surface temperature of a pizza stone. The temperature of the stone and the temperature of the hood of your grill/oven can vary, so it is recommended that you test it with one of these. So I made a glass of ice water in my Yeti mug. After a few minutes sitting it showed 32.9F. Then I check again a few minutes later and it's sporadic, 37.2F, 34.7F. I checked it from 12 inches away, which is a Spot should measure about 1 inch in diameter according to the instructions (make sure the surface is at least twice the corresponding spot diameter. So a 4 inch cup opening at 12 inches should do the trick. Eventually reached her a couple of times in a row 33.9. Low side. Then I boiled water to check the 212 degree benchmark. Same. I brought it closer, I moved it further. I tested it on a continuous boil and it was 226 and each Different times. until then on the stove until the water is almost boiling. The same. Never the same twice. Sometimes it can vary by 15-20 degrees. I just wish they had some steps or ways to ensure accuracy or to calibrate tion based on known temperatures. to ice water or boiling water. Some will say it's just a few degrees off. 15-20 is more than a few, especially since it's all about measuring the temperature as accurately as possible. If we need to guess the temperature, I can do that without this device. If your pizza is burning, it's too hot.
