Package Included: 1x Thermometers (Not Included Battery) Note: The thermometer cannot measure the internal temperature of the object; the temperature reading of this device is a simulated object, and the measured temperature of the human or animal is not correct. Specifics: Material: ABS Screen: Full Color Screen Backlight Display: Yes Battery: 2x AAA battery (Not included) Temperature range: -50~400℃/ -58°F~752°F, -50~600℃/ -58°F~1112°F Measurement Accuracy: ±(1.5%＋2℃/4℉) Response Time: ＜0.5s Emissivity: 0.1~1.0 Adjustable (Step Size: 0.01) ℃/°F Unit Conversion: Yes Object distance ratio: 12:1 Resolution: 0.1 °C / 0.1 °F Overrange Hint: "Hi" or "Low" Optional: --- IR03A: -50~400°C(-58°F~752°F) Full Color Screen --- IR03B: -50~600°C(-58°F~1112°F) Full Color Screen Feature: ✅Adjustment – Combines the latest temperature sensor technology with advanced Fresnel lenses. Improve the accuracy of the thermometer by adjusting the tolerance 0.1-1.0 based on the measured surface material. The point ratio is 12:1, which means you can measure the target at a greater distance. ✅Instant adjustment – Measure the response time from -50 to 400°C / -50~600°C and deplete 0.5S. Switch between Celsius/Fahrenheit as needed. ✅Universal – Hands-free infrared technology makes this thermometer useful for measuring temperatures in everyday and industrial environments. Use it during cooking, perform automatic/motor repairs, home/commercial repairs, etc! It has an LCD backlight so you can check the temperature even in the dark. The battery turns off automatically, so even if you forget to turn it off, it won't drain your battery. Note: 1.Please allow 1-3cm error due to manual measurement. Please make sure you do not mind before you bid. 2.The colors may have different as the difference display, please understand.
