The CUV 5 radiometer measures the total UV irradiance of the UVA and UVB components. The CUV 5 uses a photo-diode sensors with optical filters located behind a specially shaped diffuser and glass dome for a very good UV transmission and excellent directional response. Sensitivity of 300 to 500V/W/m for a typical output of 0 to 50mV, spectral range of 280 to 400nm. CUV 5 is optimised for the measurement of total UV outdoors, under natural sunlight, where the irradiance is not likely to exceed 100 W/m. It is not possible to derive the separate components of UVA and UVB from CUV 5 measurements but a suitable UVS series radiometers can be used for this application. The unit is suitable...

The SUV series of Smart UV Radiometers provide outputs for specific types of Ultraviolet radiation. The SUV range includes units optimised for a specific band of UV radiation, each unit is adapted for UVA, UVB and the UVE Erythemal (sunburn) action spectrum of the human skin. These units are identical to the SUV5 radiometer with an RS485 Modbus and 0-1V output. The SUV Series replaces the UVS Series for monitoring specific UV-A, UV-B and UV-E bands of the UV spectrum.

The CVF4 Ventilation unit is a low maintenance ventilation unit with a fan and inlet filter that provides a flow of clean air over the dome of a radiometer. The integrated heater allows the air to be warmed when necessary. The fan of the CVF4 runs continuously to reduce dust and dirt settling, to dissipate rain drops and to stabilise the dome temperature. A tacho output from the fan gives two pulses per revolution and allows remote monitoring of the fan operation using a data logger. The CVF4 is designed to be used with Kipp & Zonen CMP and SMP series pyranometers, the CGR 4 pyrgeometer, and the CUV5 total UV radiometer.
