Introduction:
1. Surface temperature measurement for coal mining equipment. Functions include laser collimation, backlight display, automatic shutdown.
2. Applicable for equipment surface temperature measurement which cannot be achieved by using traditional touch methods. (For example: moving object, charged surface, the object difficult to touch).
3. Provide max value, min value and average value measuring methods for different materials to achieve high precision measurement.
4. Upper and lower limit alarm function.
5. Measuring data storage function.
