Advantages and Uses of the Non-Contact Infrared Thermometer
Advantages of using a non-contact infrared thermometer: The non-contact infrared thermometer uses infrared technology for measurement. There is no need to contact the measured object during measurement. You only need to aim and press the trigger to quickly and accurately measure the surface temperature. The measurement data is directly displayed on the LCD display. The infrared thermometer is light in weight, small in size, easy to use, and can reliably measure hot, dangerous and other difficult-to-reach objects without contaminating or damaging the measured object.

1. When using a non-contact infrared thermometer to measure temperature, point the non-contact infrared thermometer at the object to be measured and then press the button. At this time, pay attention to the ratio between the distance and the size of the measurement area. The machine is equipped with a laser light. To aim at the object being measured.
2. Object distance ratio (D:S) refers to the ratio of the measurement distance to the surface area of the measured object. When the distance between the non-contact infrared thermometer and the measured object increases, the surface area of the thermometer and the measured object is required. bigger. D:S=12:1
3. Observation range: Make sure that the target being measured is larger than the measurement area of the machine. The minimum diameter of the measured area must be more than 1.5 square centimeters.
4. Reflectivity: The emissivity of most organic materials and paint or oxidized materials is 0.95 (already set in this machine). Smooth or polished metal surfaces may cause inaccurate measurement values. When making compensation, a surface mask must be used. Apply tape or black paint and wait to bring it to the same temperature as the material underneath before taking a temperature measurement.
5. Press the battery switch, install the battery correctly, and press the switch button to turn it on. The LCD will display the battery symbol and temperature value. The value retention time is about 7 seconds.
6. Use: According to the size of the object to be measured, select a suitable distance, aim at the object to be measured, press the button switch, and the LCD will display the temperature value and reading.
Several factors that affect the measurement accuracy of non-contact infrared thermometers:
1. Emissivity: The emissivity of a general object surface is 0.95. The emissivity of various other materials can be found from published emissivity tables.
2. Field of view: The ratio of the distance from the infrared thermometer to the object being measured and the size of the spot being measured.
3. Object distance ratio: Ensure that the area of the object being measured is larger than the spot size measured by the infrared thermometer. The smaller the area of the object being measured, the closer it should be to the words. Working principle of infrared thermometer: Infrared thermometer consists of optical system, photodetector, signal amplifier, signal processing, display output and data analysis. The optical system gathers the infrared radiation energy of the target within its field of view. The infrared energy is concentrated on the photodetector and converted into a corresponding electrical signal. The signal is then converted into the temperature value of the measured target.
