Calex has a range of short-wavelength sensors designed for measuring the temperature of most metals. Sensors of approximately 2 micron spectral response and below should be used for iron and steel, as the low and varying emissivity favours the use of shorter-wavelength sensors.
PyroUSB 2.2
• Bare metals
• 45 to 2000°C
View the data sheet
The new short-wavelength PyroUSB 2.2 can measure temperatures from 45°C to 2000°C. Its 2.0 to 2.4 micron spectral response allows a higher tolerance to errors in emissivity setting, and helps ensure accurate readings even on shiny metals.
PyroSight
• 150 to 2475°C
• Fibre optic versions available
View the data sheet
The short-wavelength models in the PyroSight Series are well-suited to the measurement of metals between 150°C and 2475°C. Versions with fibre optic sensing head are also available for harsh, high ambient temperature environments.
PRO 80 and 90
• High temperature metals
• Dual wavelength
View the data sheet
Dual-wavelength PRO 80 and PRO 90 sensors may be used to measure high-temperature metals where the emissivity varies considerably.
PRO 40 and 50
• 40 to 2475°C
• Fibre optic versions available
View the data sheet
PRO 40 and PRO 50 sensors may be used to measure metals between 40 and 2475°C in harsh conditions.
PyroUSB
• Low-temperature applications
View the data sheet
Metals at very low temperatures must be measured at longer wavelengths; an adjustable-emissivity sensor such as the PyroUSB would be appropriate in this case.
