Precautions for using handheld infrared thermometer
Handheld infrared thermometer, also known as portable infrared thermometer, is a compact and easy-to-carry infrared thermometer.
How to use a handheld infrared thermometer
1. First check the temperature measuring gun, press the transmitter button and observe whether the LCD display shows numbers;
2. Manually press the infrared transmitter on the handle of the temperature measuring gun;
3. Observe that SCAN appears in the upper left corner of the LCD display, indicating that the temperature is being collected at this time. Pause for a moment and wait until the temperature on the display no longer fluctuates greatly. Press the Panasonic button (if no activity is detected for 8 consecutive seconds, the thermometer will automatically turn off);
4. The ε character represents the emissivity, and the value displayed in the center of the LCD display is the measured value. The lower left corner can display the maximum, minimum, average temperature and temperature difference.
Precautions for using handheld infrared thermometer
1. Pay attention to your own safety when measuring temperature and stand at an appropriate distance outside the safety line;
2. When measuring the temperature of the object to be measured with a handheld infrared thermometer, the infrared thermometer should be pointed at the object to be measured, and ensure that the ratio of the measurement distance to the spot size meets the field of view requirements, not too close, not too close. Far;
3. It only measures the surface temperature, and the infrared thermometer cannot measure the internal temperature;
4. Temperature measurement cannot be carried out through quartz glass with wavelengths above 5um, because glass has very special reflection and transmission characteristics and cannot be accurately measured. It is best not to use infrared thermometers for temperature measurement of bright or polished metal surfaces (stainless steel) , aluminum, etc.);
5. Steam, dust, smoke, etc. will block the optical system of the instrument and affect accurate temperature measurement;
6. If the thermometer is suddenly exposed to an ambient temperature difference of 20°C or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes;
7. Do not aim the laser directly at your eyes, or on indirect reflective surfaces;
