Understanding Infrared Thermometers
Infrared thermometers are a popular choice in industries where temperature measurement is a critical factor in the quality of the output. They offer quick and accurate readings of an object’s surface temperature, without requiring direct contact.
The Importance of Calibration
Like any other measuring instrument, an infrared thermometer needs calibration to ensure that its readings are accurate. Calibration is crucial in industries like food production, pharmaceuticals, and manufacturing, where a slight deviation can affect the quality of the product and cause financial losses.
Calibrating an Infrared Thermometer
The process of calibrating an infrared thermometer is fairly simple and can be done by anyone. Start by reading the manufacturer’s instructions, which will give you specific guidance on how to calibrate your model.
The most common method of calibration involves using a temperature source, such as a calibrated black body, to compare the thermometer’s reading to an accurate temperature value. The thermometer’s readings should be within the acceptable range specified by the manufacturer.
Frequency of Calibration
The frequency of calibration depends on the industry and the specifications of the thermometer. As a general rule, infrared thermometers used in critical processes should be calibrated at least once a year. However, some industries may require more frequent calibration, such as every six months or even every month.
It’s also essential to calibrate the thermometer after any physical damage or exposure to extreme temperatures or humidity, which can affect its accuracy.
Hiring a Calibration Service
If you don’t have the equipment or expertise to calibrate an infrared thermometer, it’s best to hire a calibration service that specializes in temperature measurement instruments.
These services use NIST-traceable standards, which means that their equipment has been rigorously tested and certified to meet the standards set forth by the National Institute of Standards and Technology.
Having a professional calibration service ensures that your infrared thermometer is accurate and reliable, which gives you peace of mind and helps you maintain quality standards in your operations.
