Description

The MS-80S is an ISO 9060:2018 Class A pyranometer, in the top tier ‘fast-response’ and ‘spectrally flat’ sub-categories, with unprecedented low zero-offset behaviour, fast sensor response, ISO 17025 accredited calibration and a 5-year recalibration interval.

Building on the innovative patented design of the original MS-80, released in 2016, the MS-80S includes a state-of-the-art thermopile sensor, a new internal diagnostics system, and 4-channel smart interface.

The internal diagnostics system offers users visibility over internal temperature, humidity, tilt and roll angle; helping to ensure optimum performance without the need for regular physical checks; while the 4-channel smart signal transducer allows the MS-80S to easily connect to any analogue or digital measuring system, giving users a choice with Modbus 485 RTU, and SDI-12 for digital output; alongside 4-20mA, and 0-10mA (0-1V) analogue options.
