Designed to raise the bar, the MS-21 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-21 minimizes temperature differences and suppresses window heating errors.
Whatever the conditions, the MS-21 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 aluminum 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-21 achieves the highest standards for quality, accuracy, and reliability.
