that the target is at least twice as large as the spot size.

Q. How to take temperature measurement?

A. To take a temperature measurement, just point the unit at the object you wish to measure. Be sure to consider distance-to-spot size ratio and field of view. There are important things to keep in mind while using infrared thermometers:

1.Measure surface temperature only. The IR thermometer cannot measure internal temperatures.

2.Do not take temperature measurement through glass. Glass has very distinctive reflection and transmission properties that do not allow accurate infrared temperature reading. Infrared thermometers are not recommended for use in measuring shiny or polished metal surfaces (stainless steel, aluminum, etc.). (See Emissivity.)

3.Watch for environmental conditions. Steam, dust, smoke, etc., can prevent accurate measurement by obstructing the unit’s optics.

4.Watch for ambient temperatures. If the thermometer is exposed to abrupt ambient temperature differences of 10 degrees or more, allow it to adjust to the new ambient temperature for at least twenty minutes.

Q.What are the most popular applications?

A. Non-contact thermometers have many uses. The most popular include:

1.Predictive and Preventive Industrial Maintenance: check transformers, electrical panels, connectors, switchgear, rotating equipment, furnaces and much more.

2.Automotive: Diagnose cylinder heads and heating/cooling systems.

3.HVAC/R: Monitor air stratification, supply/return registers and furnace performance.

4.Food Service & Safety: Scan holding, serving, and storage temperatures.

5.Process Control & Monitoring: check process temperature of steel, glass, plastics, cement, paper, food & beverage.
