CM 4
• Heat resistant instrument design
• Extended operating
temperature range
• Excellent temperature dependency
The Kipp & Zonen CM 4 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 CM 4 is supplied as standard with a Teflon™ 10 m signal cable, optionally a 25 m cable can be factory fitted to the instrument.
The CM 4 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. Optionally the instrument can be supplied with a graph of the radiometer temperature dependence of sensitivity. Monitoring the temperature during operations allows easy data correction afterwards for improved measurement accuracy.
