MS-80 is a unique pyranometer compliant to the “Fast reponse” and “Spectrally flat” sub-category under ISO 9060:2018 Class A. The innovative patented design was inspired by the combination of latest technologies and state-of-the-art thermopile sensor, enabling a breakthrough in unprecedented low zero-offset behavior and fast sensor response.

The compact sensor with a single dome, based on an isolated thermopile detector and Quartz diffusor is immune to offsets and integrates all optional value-added functions such as a ventilator, heater and different industrial interfaces. The heater and ventilator are suggested, particularly in areas impacted by dew, frost, snow, and dust.

The MS-80A is an MS-80 with a built-in 4-20mA converter and MS-80M with built-in MODBUS converter. They are compatible with the industrial output standards. Due to the ultra-low temperature dependency and exceptional non-linearity characteristics, the converter guarantees an optimal sensor performance, under any environmental conditions.

The MS-80 pyranometers are manufactured in a consistent way followed by strict quality inspection and performance evaluation. For each sensor, the directional response and temperature dependency are measured and validated through a measurement report that comes with the sensor. EKO provides a unique calibration compliant to the international standards defined by ISO/IEC17025/9847.

The sensor has a 5 year warranty, 5 year recommended re-calibration interval and no longer the requirement for the desiccant to be changed.
