GFTH200, Digital- Hygro-/Thermometer
Low cost, pocket-sized meter for relative humidity, temperature and dew point measurements within seconds in EDP rooms, museums, churches, administrative and residential buildings, storage rooms, green houses, pools, production rooms, for cooling technology and air conditioning as well as for building engineers and for the evaluation of damage to buildings etc.
Because of the low power consumption and the integrated min-/max-value memory the GFTH200 is perfectly suitable for long term climate surveillances.
Connection possibility of an optional Pt1000 sensor.
Technical data:
Measuring range: Temp: -25.0 ... +70.0 °C; -13.0 ... +158.0 °F
%RH: 0.0 ... 100.0 %RH (recommended range: 11 - 90 %RH)
