Heat the target object (or a sample of the target material) to a steady temperature.This method involves comparing the measurements from the infrared sensor with a contact thermocouple probe that you trust and know to be accurate. You can find our emissivity tables here: Emissivity Tables (PDF) Method 2: Compare Measurements with a Contact Probe

In practice, the emissivity depends a lot on the condition of the surface, and we often find the emissivity is different on the same material in different applications. This is a rough method that will provide a sensible emissivity value to try at first, in most cases.Įmissivity tables provide a reasonable estimate of the emissivity of a material, for a given surface finish (e.g.

There are a few ways to find the right setting: Method 1: Emissivity Tables So you know you need to adjust the emissivity, but you don’t know what value to use.
#CALEX MEANING HOW TO#
The emissivity setting can be adjusted in different ways depending on the model – this might be via rotary switches, push buttons, the touch screen interface, or a configurable parameter in the sensor’s memory accessible by USB or RS485.įor more information, see our article How to Adjust the Emissivity Setting of an Infrared Temperature Sensor. Most infrared temperature sensors have an adjustable emissivity setting to suit a wider range of target materials. They can also be used on painted or non-reflective coated metals. These sensors can be used with good results on most non-reflective non-metal surfaces. Some sensors, such as the PyroCouple, have a fixed emissivity setting of 0.95, with no adjustment possible. The emissivity setting tells the sensor how emissive the surface is, and improves the accuracy of the measurement when it is set correctly. What is the Emissivity Setting of the Sensor? This is the default emissivity setting of all Calex sensors. A high emissivity makes a surface easy to measure using an infrared thermometer a low emissivity is more of a challenge.Įmissivity is usually about 0.95 for most non-reflective non-metals. For most materials, emissivity is the opposite of reflectivity. Here are some methods to help you find the right setting to use.Įmissivity is a measure of how effectively a surface emits infrared energy.

Registration will close on March 1st at 11:59 PM.For accurate results when using an infrared temperature sensor (pyrometer), the emissivity setting must be correct. If you would like to attend, please RSVP at
