  • SKU: EKO-MS-40S


The MS-40S is an ISO 9060:2018 Class C pyranometer which is based on EKO’s universal sensor platform. This sensor can be used in many meteorological networks and professional small scale PV sites where solar radiation is taken seriously.

The MS-40S uses smart sensor technology and on-board diagnostic functions which are now standard for all EKO smart sensors. This technology 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, 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.

The MS-40S with 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 MS-40S can be used with the optional MV-01 ventilator / heater or can be combined with the optional mounting kit for albedo measurements.

The MS-40S pyranometers are manufactured in a consistent way followed by strict quality inspection and performance evaluation. EKO provides a unique calibration compliant to the international standards defined by ISO/IEC17025/9847.

The sensor has a 5 year warranty with a 2 year re-calibration interval recommended and it is no longer necessary to change the desiccant.
