How it works
MS-20
Pyrgeometer
WISG traceable calibration
More accurate and lower cost than competing ‘budget’ sensors, the MS-20 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-20 upward and downward facing, with a specially coated silicon window to block solar radiation wavelengths below 4.5μm.
MS-20
The MS-20 Pyrgeometer is built for research, agricultural and architectural field applications.
More accurate and lower cost than competing ‘budget’ sensors, the MS-20 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-20 upward and downward facing, with a specially coated silicon window to block solar radiation wavelengths below 4.5μm.
Based on EKO’s universal sensor design, the MS-20 is robust, weather-proofed and compatible with the MV-01 Ventilator & Heater perfect for for continuous outdoor measurement, whatever the conditions.
Available in two variants; the MS-20T with a high grade Japanese Industrial Standard (JISC1611) thermistor and the MS-20P with a PT-100/3W IEC60751 Class A Industrial platinum resistance thermometer; 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.
