What are the main areas of use for infrared thermometers
Infrared thermometers have been proven to be effective tools for detecting and diagnosing electronic equipment faults. It can save a lot of expenses. With an infrared thermometer, you can continuously diagnose electronic connection problems and detect the functional status of the uninterruptible power supply (UPS) by searching for hotspots at the output filter connection on the DC battery. You can inspect battery components and power distribution panel terminals, switch gears or fuse connections to prevent energy consumption; Due to the heat generated by loose connectors and combinations, infrared thermometers can help identify insulation faults in circuit interrupters or monitor electronic compressors; Daily scanning of hot spots in transformers can detect cracked windings and wiring terminals.
How to measure temperature using an infrared thermometer
-The following are three temperature measurement techniques for Raytek non-contact thermometers:
Point measurement: measuring the total surface temperature of an object, such as an engine or other equipment
Temperature difference measurement: Compare the measured temperature of two independent points, such as connectors or circuit breakers
Scanning measurement: Detects changes in targets over a wide or continuous area. Like refrigeration pipelines or distribution rooms.
The main considerations for choosing an infrared thermometer
-Temperature range: Raytek products have a temperature range of -50~3000 degrees (segmented), and each model of thermometer has its own specific temperature measurement range. The temperature range of the selected instrument should match the specific application temperature range.
-Target size: When measuring temperature, the measured target should be larger than the field of view of the thermometer, otherwise there will be measurement errors. It is recommended that the size of the measured target exceed 50% of the field of view of the thermometer.
-Optical resolution (D: S): refers to the ratio of the thermometer probe to the target diameter. If the thermometer is far from the target and the target is small, a high-resolution thermometer should be chosen.
Accurate temperature measurement techniques
-When measuring the surface temperature of luminescent objects, such as aluminum and stainless steel, the reflection of the surface can affect the reading of the infrared thermometer. Before reading the temperature, a rubber strip can be placed on the metal surface. After the temperature is balanced, the temperature of the rubber strip area can be measured.
If an infrared thermometer can move back and forth from the kitchen to the refrigerated area and still provide accurate temperature measurement, it must be measured after a period of time in a new environment to achieve temperature balance. It is best to place the thermometer in a frequently used location.
Using an infrared thermometer to read the internal temperature of liquid food, such as soup or sauce, must be stirred before the surface temperature can be measured. Keep the thermometer away from steam to avoid contaminating the lens and causing incorrect readings.
