incl. Humidity- and Temperature Probe, TFS 0100 E

• Double display of humidity and temperature
• Compact probe for humidity and temperature measuring resp. flow rate measuring (probe exchange without re-calibration)
• Calculation of dew point temperature, dew point distance and enthalpy
• Additional NiCr-Ni-socket for surface measurement
• Min-/Max value memory, Hold function
• Serial interface, device can be connected to bus system (up to 5 devices can be connected to one PC interface)
• Battery/d.c. operation
• 2 integrated logger functions
• Optical and acoustic min-/max- alarm
• Real-time clock with day, month and year

Min-/Max-value memory: memorizing of max. and min. values for humidity, temperature, dew point etc.

Hold function: By pressing a button the current values will be "frozen".

Calculation of dew point: based upon humidity and temperature.

Calculation of dew point distance: by means of a surface meas. Calculation of enthalpy (thermal content h of the air)

Adjustment-function for atmospheric humidity measurements NiCr-Ni-temperature measuring: any standard NiCr-Ni-probe (type K) can be plugged in. Recommendation: GOF130VE (p.r.t. p. 92). A compensation value can be set for surface meas. if necessary.

Flow measurements: Two different systems for averaging are integrated:

• continuous averaging: the average value displayed is calculated using the last measurements during the averaging time set.
• averaging upon request: by starting the current measuring value will be displayed for tge averaging time. As soon as the time has expired the average value will be displayed, the device is in HOLD mode.
• selectable averaging time: 1 ... 30 seconds

Min-/Max-alarm: the measuring value is constantly monitored if they remain within the min./max. limits set.

Alarm: 3 different alarm settings

• off: alarm function not activated
• on: visual alarm via display, integrated buzzer and interface
• no Sound: alarm via display and interface
• Controlling function: with the help of the switching module
  GAM3000 (optionally) electric equipment can be switched on/off or
  alarm memoried (p.r.t. catalogue page 38)
   

Logger functions:

• manuelly: 99 data sets (data recall via keyboard or interface)
• cycle: 5.400 data sets (data recall via interface)
• adjustable cycle time: 1sec. ... 1h

Logger start and stop via the keyboard or interface. Comfortable read-out and display software (GSOFT3050) available as additional equipment.
