Infrared Thermometer
An infrared thermometer is used for measuring the temperature of the body or surface. With technical advancements, the world has changed from
mercury thermometers to more modern temperature measurement equipment. With a
large number of thermometers available, it can be a daunting challenge to
choose a temperature measurement system that is best for your loved ones.
It is equipped with an infrared sensor that helps
to take temperature measurement in a more efficient and accurate way. However,
the size of the display when selecting the thermometer also matter for clear
visibility. Infrared thermometers are certainly enticing, measuring the
temperature without directly touching it.
Advantages of Infrared Digital Thermometer:
- Easy
to operate makes it a more user-friendly device when it comes to measure
surface temperature without touching it.
- It
is able to automatically and non-destructively measure the temperature
quickly.
- Compact
and a stylish design with easy portability.
Emissivity:
Emissivity is a measure of the potential of a substance to emit
infrared radiation. It is estimated from 0.0 to 1.0 on a scale. Infrared
thermometer reading is affected when it is directed towards low emissivity
materials such as Aluminium and stainless steel.
Temperature Checking of Food With Infrared Thermometer:
Only surface temperature and not the internal temperature is
determined by Infrared thermometers. This is also not appropriate for testing
the doneness of the food products.
The Temperature of Liquid:
Before measuring the temperature of any liquid, proper stirring is
required for more accurate measurement of the internal temperature of the
liquid. The steam of the liquid may affect the accuracy of the thermometer as
it can condense it.
Distance To Target Ratio:
The distance to target ratio (DTR) or Spot Ratio informs you that
an Infrared thermometer can measure the diameter of the circle of the surface in the area at a given distance. The distance can vary from 3cm to 5 cm.
Tips to Clean Infrared Thermometer:
- Use
medical alcohol (never use soap or chemical) on a soft cloth or cotton swab.
- The lens needs to be cleaned first carefully.
The lens of the thermometer should be properly dry before using it
to avoid any error.
