GFTB 100 Precision Hygro- / Thermo- / Barometer


Precision - Hygrometer / Barometer / Thermometer

Application: Quick-response measurement of air pressure, atmospheric humidity, temperature and further derived units 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. Due to highly accurate sensors this device has notably higher precision than comparable devices. Via the additional displaying possibilities (‘dew point temperature Td’, ‘wet bulb temperature Twb’, ’absolute humidity [g/m³]’ and ’moisture content of the air [g/kg]’) the current state of the air is precisely and concretely shown. Due to the low power consumption, the device can be run permanently, for example as “weather station”.
