Three temperature measurement techniques of Raytek non-contact thermometer
1. Point measurement: measure the temperature of the entire surface of an object, such as an engine or other equipment;
2. Temperature difference measurement: compare the measured temperature of two independent points, like a connector or a circuit breaker;
3. Scanning measurement: detect target changes in a wide area or continuous area. Like refrigeration lines or switch rooms.
The main considerations for choosing an infrared thermometer are:
1. Temperature range: Each type of thermometer has its specific temperature range. The temperature range of the chosen instrument should match that of the specific application.
2. Target size: When measuring temperature, the measured target should be larger than the field of view of the thermometer, otherwise there will be errors in the measurement. It is recommended that the measured target size exceed 50% of the pyrometer's field of view.
3. Optical resolution (D:S): the ratio of the probe of the thermometer to the diameter of the target. If the thermometer is far away from the target and the target is small, a high-resolution thermometer should be selected.
Accurate temperature measurement tips; when measuring the temperature of shiny surfaces, such as aluminum and stainless steel, the reflection of the surface will affect the reading of the infrared thermometer. Before reading the temperature, put a rubber strip on the metal surface, and measure the temperature of the strip area after the temperature is balanced. In order for the infrared thermometer to walk back and forth from the kitchen to the refrigerator and still provide accurate temperature measurements, it must be measured after a period of time in the new environment to achieve temperature equilibrium. It is best to place the thermometer in a place that is frequently used.
Use infrared thermometers to read the internal temperature of fluid foods, like soups or sauces, that 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.
