Kipp & Zonen - Model CM4 - Pyranometer
From Instruments - Solar - Solar Tracking and PV Soiling
The CM4 High Temperature Pyranometer is a radiometer specially designed for measuring solar or artificial light irradiance under the most extreme temperature conditions. With an operating temperature range of -40 ºC to +150 ºC and measurement up to 4000 W/m² it is a unique product. All the radiometer components are specially selected for their ability to withstand these extremely high temperatures and irradiance. The CM4 is supplied with a 10 m high temperature signal cable fitted to the instrument. The CM4 High Temperature Pyranometer has internal first-order temperature compensation, but it is also supplied with a built in Pt-100 temperature sensor to provide additional information on the measurement conditions.
Product Details
Monitoring the temperature during operations allows easy data correction afterwards for improved measurement accuracy. CM4 is supplied with a calibration table that gives the instrument sensitivity for a number of measurement temperature ranges and the maximum error in the measured irradiance values within each range. The screw-in drying cartridge is easy to remove and the replacement desiccant is supplied in convenient refill packets.
