Mini-DIN-socket |
|
NiCr-Ni-connection:
|
Miniature flat-pin
plug |
|
Display: |
2 four digit LCDs (12.4mm resp. 7mm
high) for humidity and temperature (dew point
etc.), min./max. values, hold function, etc.
as well as additional functional arrows. |
|
Working temperature: |
-25 to +50°C |
|
Relative humidity:
|
0 to 95% r.h., non-condensing |
|
Storage temperature: |
-25 to +70°C |
|
Min-/Max value memory: |
memorizing of min. and
max. values for humidity, temperature, dew point etc.. |
|
Hold function: |
by pressing a button the current meas. value and the
corresponding temperature will be 'frozen'. |
|
Pushbuttons:
|
6 membrane keys for ON/OFF-switch, selection of
measuring range, min- and max-value memory, hold-function, etc. |
|
Interface: |
serial interface (3.5mm jack
connector) direct
connection to RS232 interface of a PC via electrically isolated interface adapter GRS
3100 or GRS3105 (p.r.t. accessories)
or via USB3100 to the USB-interface |
|
Power supply: |
9V battery, type IEC 6F22 (included)
as well as additional d.c. connector (internal pin diameter1.9 mm) for external
10.5-12 V direct voltage supply (Suitable power supply: GNG10/3000) |
|
Low battery warning: |
'BAT' |
|
Power-Off-Function: |
Device will be
automatically switched off, if no key is pressed/ no interface communication takes place for the time of the
power-off delay.
The power-off delay can be set to values between 1 and 120
min.; it can be completely deactivated. |
|
Power consumption: |
approx. 2.5 mA (with TFS
0100) |
|
Dimensions (device): |
142 x 71 x 26 mm (L x W x
D) |
|
Housing |
Impact-resistant ABS plastic housing, membrane keyboard,
transparent panel.
Front side IP65, integrated pop-up clip for table top or
suspended use. |
|
Weight: |
approx. 160 g (battery incl.) |
|
Calculation of dew point: |
Dew point temperature
calculation based upon current humidity
and temperature values. |
|
Adjustment of atmospheric humidity measurements: |
TFS0100
type probes can be
adjusted by means of a humidity normal line to compensate for sensor drift. |
|
NiCr-Ni temperature measuring: |
any standard NiCr-Ni-probe
can be plugged in. For surface meas. we recommend GOF130VE. A compensation value (to compensate for the loss when
transferring heat from the meas. object to the probe) can be set and switched on/off for surface meas, if necessary |
|
Calculation of dew point distance: |
The dew point distance between the ambient atmosphere and e.g.
a wall surface can be displayed by means of a surface measurement. |
|
Calculation of enthalpy:
|
The enthalpy
calculation gives the thermal content h of the air. |
|
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: As soon as the device has
been switched on or the hold-key has
been pressed, the device starts averaging for the averaging time set.
During measuring the current measuring value will be displayed.
As soon as the averaging time has expired the average value will be displayed,
the device is in the HOLD mode.
- selectable averaging time: 1 to 30 seconds
|
The GMH 3350 has the following additional features
compared to the GMH 3330:
- Min-/Max-alarm:
The measuring value of the channel selected (humidity,
temperature T1, temperature T2,
dew point, dew poinat distance or enthalpy) is constantly
monitored if they remain within the min./max. limits set.
- Alarm: 3 different alarm settings can be selected:
"off" - alarm function
not activated
"on" - visual alarm
via display, interface alarm, alarm sounded via integrated horn
"no.So."
- visual alarm via display and interface alarm
With the
help of the switching module GAM 3000 electric
equipment can be switched on/off via the alarm function.
GAM 3000 can also be configurated as
a controller.
- 2 integrated logger functions:
2 logger functions can be selected:
-STORE: Memorizing of meas. values
(humidity, temperature T1, temperature T2,
dew point temperature, dew point distance and enthalpy) and of the current
time,
date by pressing a button.
All values can be called up from the memory via keyboard or interface at any
time.
Number of memory units: 99 data sets.
-CYCLE: Cyclic, continuous memorizing
of meas. values (humidity, temperature T1,
temperature T2, dew point temperature, dew point distance and enthalpy).
Cycle time adjustable: 1 sec to 1 hour, freely selectable.
Number of memory units: 5400 data sets (16200 meas. values).
Use keyboard or interface to start/stop logger.
Comfortable readout and display software available for data
processing (GSOFT3050)
-Real-time clock: integrated clock with date and year
