MS-80M Pyranometer
Pyranometer with Modbus technology. EKO new generation digital ISO 9060:2018 Class A pyranometer has the lowest measurement uncertainty.
MS-80M is a "Spectrally flat" ISO 9060:2018 Class A pyranometer. 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 behaviour and fast sensor response.
The compact sensor with single dome, based on a 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 recommended, particularly over areas impacted by dew, frost, snow, and dust.
The MS-80M is a MS-80 with built in MODBUS RTU 485 converter, which is compatible to 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 5 years warranty, 5 years recommended re-calibration interval and no longer the requirement for the desiccant to be changed.
