Selection Guide for Purchasing an Infrared Thermometer
Non-contact infrared temperature measurement products include three series: portable, online and scanning, with various optional accessories and corresponding computer software. Each series has various models and specifications. Among various models of thermometers with different specifications, it is very important for users to correctly select the model of infrared thermometer. Here are some thinking steps for the selection of portable infrared thermometers for buyers' reference.
The choice of infrared thermometer can be divided into three aspects:
Determine the temperature measurement range:
Each model of thermometer has its own specific temperature measurement range. Therefore, the temperature range that users want to use must be considered accurately and comprehensively, and should not be too narrow or too wide.
Determine optical resolution (range and sensitivity):
The optical resolution is determined by the ratio of D to S, which is the ratio of the distance D between the thermometer and the target to the diameter of the measurement spot S. If you want to measure long distance and small targets, you should choose a thermometer with high optical resolution. The higher the optical resolution, that is, the greater the D:S ratio, the higher the cost of the thermometer.
Measurement in bright light background
If the target being measured has a strong background light (direct sunlight or strong lamp), the accuracy of the measurement will be affected. At this time, objects should be used to block the strong light of the direct object to eliminate background light interference.
Simple operation and easy to use:
A portable infrared thermometer should be intuitive, simple to operate, and easy to use. It is a small, lightweight instrument that integrates temperature measurement and display output and can be carried by people for temperature measurement. The temperature can be displayed on the display panel. and output various temperature information, some of which can be operated by remote control or through computer software programs.
