Technical issues with infrared thermometers
What are the common applications?
Answer: There are many uses for non-contact thermometers
Most commonly used for: Predictive and preventive industrial maintenance: inspecting transformers, switchboards, connectors, switchgear, rotating equipment, furnaces and more.
Automotive: Diagnose cylinder heads and heating or cooling systems.
Heating general and air conditioning systems/dampers: Monitor air stratification, supply/return dampers and furnace performance.
Food service and safety: Test storage, serving and storage temperatures.
Process Control and Monitoring: Checking process temperatures in steel, glass, plastics, cement, paper, food and beverage processes.
Q: How to measure temperature?
Answer: To take a temperature measurement, simply point the instrument at the dot you want to measure. Be sure to consider the distance to size ratio and field of view.
Important things to remember when using an infrared thermometer are:
1. Only measure the surface temperature. Infrared thermometers cannot measure internal temperatures.
2. Do not measure temperature through glass. Glass has different reflective and transmissive properties than other materials, affecting infrared temperature readings.
3. It is recommended not to use an infrared thermometer to measure bright or polished metal surfaces (stainless steel, aluminum, etc.).
4. Pay attention to environmental conditions. Steam, dust, smoke, etc. cover the lens and hinder measurement.
5. Pay attention to the ambient temperature. If the thermometer encounters a sudden environmental temperature difference of more than 10 degrees, allow the instrument to adapt to the new ambient temperature for at least twenty minutes.
6. Different objects have different emissivities.
Q: What is the difference between non-contact infrared thermometers and traditional contact thermometers?
Answer: Compared with non-contact infrared temperature measurement and contact temperature measurement, it has the following characteristics:
Non-contact infrared temperature measurement:
1. Non-contact temperature measurement has no effect on objects
2. Detect the surface temperature of the object
3. Fast response speed, capable of measuring moving objects and transient temperatures
4.Wide measuring range
5. High measurement accuracy and small resolution
6. Can measure temperature in small areas
7. Can measure point, line and surface temperature at the same time
8. Can measure both absolute temperature and relative temperature
