MS-21SH

Designed to raise the bar, the MS-21SH Pyrgeometer is research-grade, accurate, robust and delivers superior stability independent of the sensors’ operating temperature. Based on a new design concept and built for consistency, the MS-21SH minimises temperature differences and suppresses window heating errors.

Whatever the conditions, the MS-21SH measures longwave downwelling radiation and longwave net radiation in a wide spectral band without needing a sun tracker with a shading device or shadow ring. It features a silicon meniscus dome with solar blind interference filter and hard carbon coating, a new thermal coupling design, onboard temperature compensating electronics, and a unique aluminium alloy sun shield.

With a 5-year Warranty, World Infrared Standard Group (WISG) traceable calibration, and PT-100/4W IEC60751 Class A Industrial platinum resistance thermometers and temperature sensors; the MS-21SH achieves the highest standards for quality, accuracy, and reliability.

The MS-21SH built on that achievement with the addition of Modbus 485 RTU and SDI-12 digital outputs for improved compatibility with data loggers and SCADA systems; also introducing new internal diagnostic systems, now standard to all S-Series sensors, offering visibility over internal temperature, humidity, tilt, and roll angle; helping to ensure optimum performance without the need for regular physical checks.

These features, along with a new low power consumption integrated solid-state window heater make the MS-21SH one of the best value sensors available; ideal for hard to reach locations, and monitoring networks with restricted access.

Based on EKO’s universal sensor design, the MS-21SH is robust, weather-proofed and compatible with the MV-01 Ventilator & Heater perfect for for continuous outdoor measurement, whatever the conditions.

Each unit comes with a 5-year warranty and World Infrared Standard Group (WISG) traceable calibration assuring top-quality performance and reliability for every application.
