Review on 🌡️ Self-Calibrating Digital Infrared Laser Thermometer -58°F to 1022°F (-50°C to 550°C), Non-Contact IR Temp Gun for Kitchen Cooking, Automotive, HVAC and Industry with Backlit Display by Richard Nonya

This isn't a bad heat gun for $. If you know or can understand or learn from instructions and diagrams. How to calibrate (use analog or normal thermometer as standard temperature) and set EMS according to attached table. Then you can get a fairly accurate temperature. Readings, within +_- 1 degree. To switch from c to f, press and hold the left button for 2 seconds or turn off the laser with the right button 2. The center button selects the modes that appear on the screen. Then use the r+l keys to increase or decrease the values. Works just like everyone else. None of them are automatic. They are delivered from the factory with preset standard settings. But you can change them. So for $1, this one does the same thing as the more expensive models. And if you don't like Revain, give them a call, they'll send you another model and give you a free returns label.
