Chp 1
• Fast response time
• Excellent temperature dependence of sensitivity
• Excellent linearity
The CHP 1 pyrheliometer is the latest development in the field of solar radiation measurement. Building forth on the legacy of the CH 1, this instrument offers further improved accuracy and reliability.
CHP 1 fully complies with the most current ISO and WMO performance criteria for First Class Normal Incidence Pyrheliometer. Every CHP 1 is calibrated upon manufacture, and is supplied standard with a WRR (World Radiometric Reference) traceable calibration certificate.
The CHP 1 is fitted with a high quality connector for easy installation and maintenance. The drying cartridge ensures trouble free operation.
As standard CHP 1 come with both Pt-100 and 10k thermistor temperature sensors.
The instrument covers the total solar spectrum between 200 to 4000 nm. CHP 1 is intended for use with any model Kipp & Zonen two-axis Tracker.
The CHP 1 is the perfect choice for high accuracy direct solar radiation measurements.
