The MS-20SH Pyrgeometer is built for research, agricultural, and meteorological field applications.
More accurate and lower cost than competing ‘budget’ sensors, the MS-20SH is designed to capture downward atmospheric longwave radiation from 4.5μm to 42μm and can measure the net radiation between the earth and the atmosphere by using two MS-20SH upward and downward facing, with a specially coated silicon window to block solar radiation wavelengths below 4.5μm.
The MS-20SH 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-20SH 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-20SH 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.
