MS-80S is a “Spectrally flat” ISO 9060:2018 Class A pyranometer with a unique “Fast response” . 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 MS-80S with smart sensor technology and onboard diagnostic functions is now standard for all EKO smart sensors. It preserves the high accuracy of the sensor while complying with the various output standards used in the industry. The new Smart signal transducer allows selecting from 4 types of output in one unit (MODBUS 485 RTU, configurable SDI-12, 4-20mA, configurable 0-10mA / 0-1V with external optional 100Ω precision shunt resistor). The new electronics ensure a great benefit for system integrators who work with various industrial interface standards.

This new Smart transducer will also have additional features such as internal temperature and humidity sensors and a tilt sensor for remote sensor diagnostics. These additional internal sensors will help the user to monitor the stability of the irradiance sensors as well as to ensure its proper installation and maintenance practices.

The optional MV-01 heater and ventilator are recommended, particularly over areas impacted by dew, frost, snow, and dust. 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-80S 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. A setting report is provided with all parameters which were set and tested during manufacturing (current range settings, digital output communication settings, Tilt position calibration, Relative humidity and sensor temperature).

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