Teknik Bilgi

Relative humidity RH Sensor Capacitive Measuring range 0…100 %RH -40…+85 °C Dew point Td Working range -40…+80 °C Accuracy ±2.5% (0…85 %RH) / ±3.5% (85…100 %RH) @ T=15…35 °C and air speed < 0.25 m/s (*) (2.5 + 1.5% reading)% @ T= remaining range See table for Dewpoint Resolution 0.1% Temperature influence 2% on the whole temperature range Hysteresis and repeatability 1 %RH Response time (T90) <20 sec. (air speed = 2 m/sec and stable temperature) Long-term stability 1%/year (*) The instruments are preset to operate in still air. To operate in circulating air (e.g. in a climatic room), the operating mode of the instruments must be changed. Temperature T Sensor NTC 10kΩ Measuring range -30…+85 °C (-22…+185 °F) Accuracy (except models with current output) ±0.2 °C ±0.15% of reading within 0…70 °C ±0.3 °C ±0.15% of reading within -30…0 °C, 70…85 °C Accuracy (for models with current output) ±0.5°C ±0.15% of reading within -30…+85 °C Resolution 0.1°C Response time (T90) <30 sec. (air speed = 2 m/sec) Long-term stability 0.1°C/year Carbon dioxide CO2  (for models HD4617B…) Sensor Dual wavelength NDIR Measuring range 0…5000 ppm Working range -5…50 °C Accuracy ±(50 ppm+3% of reading) @ 20 °C and 1013 hPa Resolution 1 ppm Temperature influence 0.1 %f.s./°C Response time (T90) <120 sec. (air speed = 2 m/sec and constant temperature) Long-term stability 5% of the measure / 5 years
