Model PMA2144 Digital Class C Pyranometer
Solar Light’s ISO 9060:2018 Spectrally Flat Digital Class B and Class C Pyranometers measure global hemispherical radiation from 300 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 Spectrally Flat Digital Class B and Class C Pyranometers measure global hemispherical radiation from 300 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 a single glass dome. The precision optical glass dome acts 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. Along with the processing algorithm, it is programmed into a memory chip embedded into the sensor.
The primary technical differences between the ISO-Classified Class B Model PMA2145 and the ISO-Classified Class C Model PMA2144 are as follows:
