6 High-quality Standard Accuracy ± 2% r.h. ± 5% r.h. Operating range 0…100% r.h. 0…95% r.h. Sophisticated measuring technology Housing-dependent temperature compensation was made possible with microprocessor technology. As a result, humidity measurements are accurate across the entire temperature range and not only at 23 °C. Protection against radiation Radiation protection is available as an option for the measurement of outdoor humidity. Absolute humidity and enthalpy Acquisition of absolute humidity and enthalpy is made possible with a combined humiditytemperature sensor and an absolute...
