IR20 is a research-grade pyrgeometer suitable for high-accuracy longwave irradiance measurement in meteorological and climatological applications. Thanks to Hukx's technological innovation, IR20 is offered at a significantly lower price level than competing models of the same performance level. IR20 can measure during both day and night. In the absence of solar radiation, model IR20WS measures with even higher accuracy due to its wider spectral range. IR20 measures the longwave or far-infrared radiation (FIR) received by a plane surface, in W/m2, from a 180 ° field of view angle. In meteorological...

IR20 & IR20WS design & benefits – breakthrough pricing: High performance at a significantly lower price level, as a result of Hukx’s technological innovation. – temperature dependence correction via measurement function: Far more accurate than internal temperature compensation, especially at extreme temperatures. Every pyrgeometer is supplied with temperature coefficients to enter into the equation. – high sensitivity: With sufficient input signal, a typical data logger no longer significantly contributes to measurement uncertainty. – low thermal resistance of the sensor: Unlike competing designs,...
