Double/difference quick-response thermometerwith integrated alarm and logger function !Additional features as compared to the GMH 3230:l2 different logger functions- Manual memorizing of the measuring values by pressing a button(max. 99 data sets - channel 1, channel 2, difference)- Continuous memorizing of a max. of 5400 data sets(= 16200 measuring values)lMin-/Max-alarmlAlarm sounded via integrated hornlReal-time clock with date and yearGMH 3250 access. not incl.Digital-precision quick-response thermometer for thermocouplessimultaneous connection of 2 plug-in probes (p.r.t. p. 7, 14, 15, 90/91)Specification :Thermocouples: K, J, N, S, TMeasuring range, resolution, accuracy: p.r.t. GMH3230Working temperature: 0 to +50°CRelative humidity: 0 to +95%r.h. (non-condensing)Probe connections: 2 jacks for flat-pin plugDisplay, pushbuttons: p.r.t. GMH3230Interface: Serial interface (3.5mm jack connector),direct connection to RS232 interface of a PC via electricallyisolated interface adapter GRS3100 or GRS3105 (p.r.t. accessories).Min./max. value memory: Memorizing of max. and min. values forprobe 1, probe 2 and difference.Hold function: By pressing a button the current values fortemperature 1, temperature 2 and difference will be memorized.Power supply: 9V-battery, type IEC 622 (included) as well asadditional d.c. connector (internal pin Ø 1.9mm) for external 10-12Vdirect voltage supply.(suitable power supply: GNG10/3000)Low battery warning: and ' bAt 'Power-Off-function: Device will be automatically switched off ifno key is pressed/no interface communication takes place for thetime of the power-off delay. The power-off delay can be setbetween 1 and 120 min.; it can be completely deactivated.Housing dimensions: 142 x 71 x 26 mm (L x W x D)Impact-resistant ABS plastic housing, membrane keyboard,transparent panel. ront side IP65, integrated pop-up clip fortable top or suspended useWeight: approx. 155 gSpecial applications:Difference measurements: with a resolution of 0,1° or 1°.Temperature difference probe 1 - probe 2 can be displayed if 2probes are connected.Tare/diff-function: Press button to set the difference display'probe 1 - probe 2' to zeroZero-point offset entry: By entering the offset temperature theparameter can be moved parallel to the calibration graph.Compensation value for surface measurements:A compensation value (to compensate for the loss whentransferring heat from the meas. object to the probe) can be setand switched on/off for surface measurements if required.additional features of the GMH 3250 as compared to the GMH 3230:Min-/Max-alarm: The meas. values of probe 1 or 2, probes 1 and2 or the temp. difference are constantly monitored reg. the min.and max. values set.- Alarm: 3 different alarm settings can be selected:"off" - alarm function not activated"on" - visual alarm via display, interface alarm, alarm soundedvia integrated horn."no.So." - visual alarm via display and interface alarmWith the help of the switching module GAM3000 electric equipmentcan be switched on/off via the alarm function. (GAM3000 can alsobe configurated to act as a controller - p.r.t. page 38)Logger functions: 2 logger functions can be selected:- Store: Memorizing of temp. values (probe 1, probe 2 and temp.diff.) and of the current time, date by pressing a button. All valuescan be called up from the memory via keyboard or interface atany time.Number of memory units: 99 data sets.- Cycle: Cyclic, continuous memorizing of temp. values (probe 1,probe 2 and temp. difference). cycle time adjustable: 1 sec to1 hour, freely selectable.Number of memory units: 5400 data sets (= 16200 meas. values)Use keyboard or interface to start/stop logger.
