Pyrgeometers

Pyrgeometers use silicon windows to transmit infrared radiation and these have an internal thin film coating that blocks short-wave solar radiation from reaching the broadband thermopile detector.

CGR4 Pyrgeometer

The CGR4 is a pyrgeometer, designed for top level solar radiation monitoring networks such as the Baseline Surface Radiation Network (BSRN) of the World Meteorological Organisation for the meteorological measurements of downward atmospheric longwave radiation. The CGR4 uses a thermopile detectors and has a sensitivity of 5 to 15V/W/m in..

SGR4 Smart Pyrgeometer

SGR4 Smart Pyrgeometer

The SGR4 is a Smart Pyrgeometer, designed to provide meteorological measurements of downward atmospheric long wave radiation. The construction of SGR4 pyrgeometers is identical to the CGR4 pyrgeometers but it includes a Modbus interface and amplified analogue output. The SGR4 uses a thermopile detector in a spectral range of 4.5..

CVF 4 Ventilation Unit

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 ...
