HYGROMETER - THERMOMETER

The HD 8501 is a portable instrument with interchangeable probes for immediate measurements of relative humidity and temperature. The humidity-sensitive element is a condenser. The sensor has excellent linearity and is insensible to temperature variations in the range 0...40°C: outside this range the temperature coefficient is negligible; (±0.05% R.H./°C). Temperature is measured by a Pt100 platinum thermoresistance. The measuring range is limited by the working temperature of the humidity sensor
(-10...+70°C). The sensor is flat with a high surface/volume ratio, which allows a fast response.
