UVB Sensor
Skye offer sensors to measure light levels in the Ultraviolet A and Ultraviolet B wavebands. The wavelengths used in these sensors are according to CIE standards.
- The dimensions and overall look of these sensors are similar to that of our other sensors. The housing is black aluminium and sealed to IP67 standards.
- The light sensor head is cosine corrected and has been designed with an integral amplifier to give a voltage output for use with most dataloggers, computers, PLCs, etc.
- Sensors calibration is traceable to NPL and each sensor is issued with a calibration certificate.
