The MS-20SH Pyrgeometer is a high-performance longwave radiation sensor designed for research, agricultural, and meteorological applications. It accurately measures atmospheric longwave radiation across a 4.5–42 μm spectral range and can be paired to measure net longwave radiation between the Earth’s surface and the atmosphere. Featuring Modbus RS-485 RTU and SDI-12 communication, integrated sensor diagnostics, and a low-power solid-state window heater, the MS-20SH delivers reliable, low-maintenance performance in demanding environments.
