Spectrally Flat
The S-Series ISO 9060:2018 MS-40S Class C Pyranometer is a cost-efficient part of the most accurate, reliable and robust family of pyranometers in the world, and the class-leading solution for system integrators, agrometeorological networks, and professional small-scale PV sites.
The S-Series MS-40S ISO 9060:2018 Class C pyranometer is a cost-efficient part of the most accurate, reliable and robust family of pyranometers in the world, and the class-leading solution for system integrators, agrometeorological networks, and professional small-scale PV sites.
Built with the same unique S-Series features as the Class A MS-80S and Class B MS-60S, the MS-40S comes with EKO’s 4-channel smart interface for compatibility with 99% of data loggers, DAQ, and SCADA systems, plus internal diagnostic sensors for remote visibility over internal temperature, humidity, tilt and roll angle; ensuring optimum performance with reduced maintenance costs.
With Level A EMI/EMC electronic surge filter and protection, 5-year warranty, lifetime desiccant, and ISO 17025 accredited calibration, the MS-40S is the toughest, most reliable, and advanced Class C pyranometer available.
- 5 year warranty & recommended 2 year recalibration interval
- Smart 4 channel Analogue & Digital Interface
- Level A EMI/EMC electronics surge filter & protection
- Internal Diagnostics for temperature, tilt, roll, and humidity
