Features Wide Measuring Range: ‑50℃~550℃ (‑58℉~1022℉), accurate to ±(1.5% reading +2℃/4℉), quick response time and fast start. Support free switching between Celsius and Fahrenheit. LCD Display: The infrared thermometer has an LCD display, the data is clearer, bigger and effective. Open the backlight and even measure in the dark. Accurate and easy to read, you can open and turn off the backlight and laser independently. High Temperature Warning LED Indicator: With red warning light indication. When the measured temperature exceeds the set range, the indicator light will turn red and an alarm will be issued. Easily detect whether a specific temperature is reached or exce Accurate Aiming Function: The 12‑point laser pointer accurate aiming function, with the ratio of D:S=12:1, uses 12 points to form a circular indicating measurement area, which is more precise and clear. Supports data hold, and automatically shuts down after 10 seconds. Low batter Specially Designed With Non‑Slip Lines: No slipping during operation, easy and convenient.
