Non contact Infrared thermometer plays a important role in our day to day life, by taking temperature reading of
hazardous or physically inaccessible objects such as high-voltage parts without coming close to it. Using Infrared thermometer is also very easy, just aim the object and press the button and you will get the reading on the LCD display. Another reason for its popularity is they provide reading very fast just in few seconds, users don’t have to wait for minutes to get the reading.
Infrared (IR) thermometers do not measure the temperature of the object, rather they measure reflected infrared light emitted by the object. This reading can be correlated to a specific surface temperature of the product being measured. All IR thermometers calculate a temperature value based upon an assumption concerning the emissivity character of the measured object. The sensors of the infrared thermometer collect the energy reflected from the targeted object, which is then amplified and converted into a voltage output. This voltage reading is further converted into digital temperature reading by CPU and displayed on the LCD display.
Factors That Affect IR Thermometer Reading
Infrared thermometers provide very fast temperature reading and are generally very accurate. But there are several factors that can affect the temperature readings:
- Distance to Spot ratio (D:S ratio): D:S ratio indicates the size of the measured area of the object and the distance between the object and the IR thermometer.
- Emissivity: Emissivity is generally set at 0.95 for most models but can be reset for higher end expensive models of IR thermometer. Emissivity varies depending on the colour, reflectivity, shape, etc. of the object being measured. For large volume orders emissivity can be set specific to the product to be measured for greater accuracy.
- Range: The farther the distance from the object to be measured the lower the accuracy of temperature reading.
