Atlas offers various sensors measuring irradiance and temperature to operate and to calibrate your weathering instruments.
XENOSENSIV are on-rack sensors either connected to the instrument controller via slip rings or radio control. All XENOSENSIV sensors are 2-in-1 type, being able to monitor both irradiance in a certain wavelength range and black standard (BST) or black panel (BPT) temperature.

XenoCal sensors are Atlas’ premium calibration sensors with ISO 17025 certificates for both irradiance and BST calibration sensors. All Atlas XenoCal sensors are easy-to-use with XenoSoft software for the quick visualization and analysis of the measured values.

SunCal sensors have been designed to provide low-cost DIY calibration tools for the complete SUNTEST® instrument series, covering the models CPS+, XLS+ and XXL+. All Atlas SunCal sensors are easy-to-use with XenoSoft software for the quick visualization and analysis of the measured values.
