    Description

    GFTB 200, Precision Hygro/Thermo/Barometer

    • relative humidity, temperature and air pressure in just one instrument
    • additional derived units: dew point temperature, wet bulb temperature, moisture content and absolute humidity
    • alarm function with integrated horn
    • min-/max-value memory for all measuring ranges
    • extremely low power consumption (>6500 operating hours)
    • PC interface
    GFTB 200 enables you to take quick-response measurements of air pressure, atmospheric humidity, temperature and further derived units. Due to highly accurate sensors this device has a notably higher precision than comparable devices.
    The dew point indication of the GFTB 200 furthermore provides an effective protection against possible humidity damages caused by condensation water development in buildings and thus also against mould infestation. The integrated alarm function reminds the user also acoustically on a reasonable ventilation, whereby an optimal and efficient use of heating energy is made possible. By means of the integrated interface and the optional EBS 20M software the device can be used as a mobile weather station with additional long-term recording. Via the additional displaying possibilities ("dew point temperature Td", "wet bulb temperature Twb", "absolute humidity [g/m]" and "moisture content of the air [g/kg]") the current state of the air is precisely and concretely shown.
    Applications:
    • mobile weather station
    • 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
    • for the evaluation of damage to buildings etc.

    humidity: 2,5 %RH (at range 11 to 90%)
    air pressure: 1,5 mbar (750...1100 mbar)
    Measuring probe: temperature: Pt1000
    humidity: capacitive polymere humidity sensor
    air pressure: piezoresistive pressure sensor hybrid
    Response time: T90 = 10 sec.
    Display: 4-digit, approx. 11mm high LCD-display
    Operation elements: 3 keys for ON/OFF, min-/max-value display, hold
    Nominal temperature: 25C
    Operating conditions: Electronics: -25...70 C; 0...80 %RH (non-condensing)
    Sensors: -25...70 C; 0...100 %RH
    Power supply: 9V-battery type IEC 6F22
    Power consumption: approx. 30A at 1 meas. / 60s (mode SLOW)
    approx. 70A at 1 measurings / sec. (mode FAST)
    Low battery warning: "BAT"
    Auto-off function: when Auto Off is activated, the device switches auto-matically off, if keypad is not attended for a longer time (selectable 1..120min).
    Interface: serial port, to be connected directly to a USB port of a PC via the galvanically isolated interface converter USB 3100 or USB 3100 N (optional accessories).
    Min./max. value memory: Min and Max measuring values are stored for all ranges.
    Hold key: the current measuring will be "frozen" (for all ranges)
    Configurable display: The device can be configured by the user: display all measuring values alternating (2 or 4 sec. Cycle) or permanent with manual choice. Not required values can be suppressed.
    Sea level adjustment: The displayed value of the barometer can be converted to air pressure at sea level. (therefore the altitude above sea level has to be entered)
    Tendency indicator (for barometer): air pressure falling/increasing
    Offset and Scale: digital offset- and scale adjustment of all sensors
