In the field of meteorological measurement, it can be used for measuring longwave radiation (far infrared region). The measurement targets wavelengths exceeding 4.5 μm.
Mainly used in the field of meteorological measurements for measuring longwave radiation (far infrared region). The measurements target wavelengths exceeding 4.5 μm. Longwave radiation can be obtained from the output signal of the thermopile and the temperature of the longwave radiometer, with the temperature measured by a built-in 10kΩ NTC in the longwave radiometer. By adding another longwave radiometer to measure upward infrared radiation and an albedometer to measure shortwave radiation (<3 μm), it can also be used for energy balance investigations. Two versions of the longwave radiometer are available: ● LPPIRG01: μV/(W/m²) output ● LPPIRG01S: RS485 Modbus-RTU output *Provided with a calibration report obtained from outdoor comparative measurements (for at least one clear night) with a reference instrument calibrated at WRC (World Radiation Center). ▼ ISO9060:2018 compliant longwave (infrared) meter ▼ Measurement range -300 to +300 W/m² ▼ Built-in silica gel cartridge for condensation prevention (replaceable) ▼ Robust construction designed for long-term use, M12 connector connection
