Three Temperature Measurement Techniques for Raytek Non-Contact Thermometers
1, point measurement: determine the temperature of the entire surface of the object, like an engine or other equipment;
2, temperature difference measurement: compare the measured temperature of two independent points, like connectors or circuit breakers;
3, scanning measurement: detection in a wide area or continuous area target changes. Like refrigeration lines or power distribution rooms.
Select infrared thermometer main considerations:
1, temperature range: each model of the pyrometer has its specific temperature measurement range. The temperature range of the selected instrument should match the temperature range of the specific application.
2, the target size: temperature measurement, the measured target should be larger than the field of view of the pyrometer, otherwise there is an error in the measurement. It is recommended that the size of the measured target exceeds 50% of the field of view of the pyrometer.
3, optical resolution (D: S): that is, the pyrometer probe to the target diameter ratio. If the pyrometer away from the target, and the target is small, you should choose a high-resolution pyrometer.
Accurate temperature measurement techniques; when measuring the surface temperature of luminous objects, such as aluminium and stainless steel, the reflection of the surface will affect the infrared thermometer readings. Before reading the temperature, you can put an adhesive strip on the surface of the metal, and after the temperature is balanced, measure the temperature of the adhesive strip area. For an infrared thermometer to be able to move back and forth from the kitchen to the refrigerated area and still provide accurate temperature measurements, it should be placed in a new environment for a period of time to equilibrate the temperature before taking measurements. It is best to keep the thermometer in a location where it will be used frequently.
Use an infrared thermometer to read the internal temperature of a fluid food, such as a soup or sauce, which must be stirred and then the surface temperature can be measured. Keep the pyrometer away from vapours to avoid contaminating the lens, which could lead to incorrect readings.
