IR01B Industrial Thermometer 50℃~550℃ (58℉~1022℉) Portable Infrared Temperature Tester Black Features: 1. 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. 2. High-definition color LCD display, compared with other infrared thermometers, the data is clearer, larger and the effect is better. Turn on the backlight, and it can measure even in dark. Accurate and easy to read, the backlight and laser can be turned on and off independently. 3. 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 exceeded. 4. 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 battery reminder, convenient to replace the battery in time. 5. Specially designed with non-slip lines, no slipping during operation, easy and convenient. This non-contact IR infrared thermometer can be widely used in electric power industry measurement, refrigeration, automobile, HVAC, mechanical equipment and other indoor/outdoor use.
