Review on Eventek Infrared Thermometer -50°C to 750°C (-58°F to 1382°F), Non-Contact Digital Temperature Gun with IR Laser, Ideal for Non-Body Measurements (ET327,-50°C to 750°C (-58°F to 1382°F)) by Mark Lodge

Great, I'm not 100% sure if this is correct, but I don't think it's more than a degree if it is. I use it all the time to read room temperature or fridge temp, grill temp or whatever is important for safety when frying or chilling food in a cheap fridge not sure if it's under 40% can fall. good news maybe lol. All in all it has given me a newfound respect for radiation and how weird the thermal world can look, just buy and scan around. I found it hard to stop scanning random shit lol. I might buy another one if they go up in price because it's a great deal and it's undeniably essential for cooking.
