Air oxygen measuring devicelDouble display for oxygen and temperaturelllllMeas. units: O 2-concentration O 2-partial pressure (GMH3691)Alarm detector with integrated hornAutomatic temperature compensationWide range of application: e.g. bio chemistry, medicine and foodtechnology, safety at work, air conditioning and ventilation technology,sports etc.Min./Max. value memory, Hold functionl Serial interface, device can be connected to bus system (up to 5devices can be connected to one PC interface)llBattery and d.c. operationMost simple calibration in atmospheric air36GMH 3690 GLSensor not included - please order separately!GMH 3691 GLSensor not included - please order separately!Specification :Measuring ranges:Oxygen concentration: 0,0 ... 100,0 % O 2(gaseous)Partial oxygen pressure (GMH3691): 0 ... 1100 hPa O 2Temperature: -20,0 ... 50,0 °CAccuracy: (device) ±0.1% ±1digit (O 2-concentration)±1 hPa ±1digit (O 2-partial pressure)±0.1°C ±1digit (temperature)Oxygen electrode: for suitable sensores p.r.t. page 37Sensor connection: 6-pin screened Mini-DIN-socket.Display: 2 four digit LCDs (12.4mm and 7mm high) for oxygenand temperature, and for min./ max. value, hold function, etc. aswell as additional functional arrows.Working temperature: 0 to +50°CRelative humidity: 0 to +95%r.h. (non-condensing)Storage temperature: -20 to +70°CInterface: 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: max. and min. values will be memorized.Hold function: by pressing a button the current meas. value willbe memorizedAlarm: integrated limit detector for min. or max. alarm.Pushbuttons: 6 membrane keys for ON/O-switch, selection ofmeas. range, min- and max- value memory, hold-function,calibration etc.Power supply: 9V-battery, type IEC 622 (included) as well asadditional d.c. adapter (internal pin Ø 1.9mm) for external 10-12Vdirect voltage supply. (suitable power supply GNG10/3000)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 set tovalues between 1 and 120 min. or deactivated.Power consumption: approx. 1.5 mALow battery warning: and ' bAt 'Housing dimensions: 142 x 71 x 26 mm (H x W x D), impact-resistantABS plastic housing, membrane keyboard, transparent panel. rontside IP65, integrated pop-up clip for table top or suspended use.Weight: approx. 315 g (cpl with battery and probe)Temperature compensation: automatic via temperature sensorintegrated in probe housing.Difference between GMH3691 and GMH3690:Additional features of the GMH3691:l O 2-partial pressure measuringl Compensation of atmospheric pressure by entering theatmospheric pressurel 1-point or 2-point calibrationCalibration: 1-point calibration: extremely simple quickcalibration in atmospheric air. (press button to compensate unit to 20.9%).2-point calibration (GMH3691 only): first point at atmospheric air(20.9%), second point freely selectableAir pressure compensation (GMH3691 only): The O 2concentrationwill be compensated according to the abs. atmospheric pressureset (500...2000hPa).Application: Wide range of application for your home, job andhobby! or example:- Bio chemistry: Oxygen monitoring in breeding chambers forcell cultures. Monitoring of fermenting process of fruits infermentation plants etc.- Medicine: Monitoring of oxygen concentration in respirators;checking of breathing, monitoring of oxygen concentration inincubators, oxygen tents etc.- ood technology: Monitoring of residual oxygen in packages(e.g. coffee, tea, etc.). Monitoring of oxygen content duringproduction processes.- Safety technology, safety at work: Oxygen monitoring in mines/pits, underground parking lots, wine cellars, cooling chambers,greenhouses or stores. Oxygen monitoring or alarm in case ofdanger of suffocation when working in tanks, wells etc.- Air conditioning and ventilation technology: Oxygenmeasurements, air quality monitoring, measuring of oxygenconcentration in enclosed air conditioning systems, etc.- Sport: Checking of oxygen content in compressed air breathingapparatuses (diving, etc.), oxygen monitoring for gliding.The device can only be used to check during these applications.-> no substitute for approved monitoring device!Upcharge, accessories:Suitable sensores p.r.t page 37GKK 3000 case with punched lining GMH3xxxGRS 3100 interface adapter, electr. isolatedGRS 3105 interface converter with 5 connectionpoints, electr. isolated, for the connection of 5 GMH3xxx to one PC.EBS 9M software for transmission, recording andarchiving measuring values obtained from one GMH3xxx (p.r.t. page 40).for additional spares and accessories p.r.t. pages 38, 40
