The 240-CMP3 Pyranometer is an instrument for measuring the solar irradiance. The thermopile sensor construction measures the solar energy that is received from the total solar spectrum and the whole hemisphere (180 degrees field of view). The output is expressed in Watts per meter square. The CMP3 pyranometer is designed for continuous indoor and outdoor use.
The CMP3 Pyranometer (ISO Second Class) is intended for shortwave global solar radiation measurements in the spectral range from 310 to 2800 nm. The thermopile detector measures irradiance up to 2000 W/m² with response time < 18 seconds and typical sensitivity 10 µV/W/m² that varies < 5% from ‑10 to +40 °C. Operating temperature range is ‑40 to +80 °C and the stability is better than 1% per year.
The CMP3 Pyranometer features a snap‑on white sun shield, integrated leveling, and a weatherproof connector which is supplied prewired with 10 m of signal cable for simple installation. An optional mounting rod and longer cable lengths are available. Two CMP3s can easily be mounted back‑to‑back to make a low cost albedometer.
