Model PMA1145 Analog Class B Pyranometer
Solar Light’s ISO 9060:2018 Analog Class B and Class C Pyranometers measure global hemispherical radiation from 285 to 2800nm. They utilize thermopile technology, assuring very broad spectral sensitivity, exceptional flatness, and excellent good long term stability.
Solar Light’s ISO 9060:2018 Analog Class B and Class C Pyranometers measure global hemispherical radiation from 285 to 2800nm. They utilize thermopile technology, assuring very broad spectral sensitivity, exceptional flatness, and excellent good long term stability. These pyranometers feature a sixty-four thermocouple junction sensing element. The sensing element is coated with a highly stable carbon-based non-organic layer, which delivers excellent spectral absorption characteristics. The sensing element is housed under two concentric fitting glass domes. The precision optical glass domes act as a filter, with spectral bandpass that permits the full solar spectrum to pass through to the sensor. The glass dome also protects the sensor from the elements. The sensor is a high quality blackened thermopile. Heating of the sensor by incoming solar radiation produces a signal in the µvolt range. Each pyranometer has its own calibration factor. A 10-meter long cable is also included.
The primary technical differences between the ISO-Classified Class B Model PMA1145 and the ISO-Classified Class C Model PMA1144 are as follows:
