All significant electrochemicalmeasurements can be combined:-pH/ Redox + conductivity/salinity pH/ Redox + dissolved oxygenThe backlit graphic display shows all parameters in plain text in German or English; other languages can be integrated (additionalcharges indicated on request). Large display or measurement diagram can also be represented.Use of our proven standard plug connectors guarantees that you can use our standard sensors – without additional costs due tocomplicated technology in the sensors. The device is distinguished by its impressive performance and the affordable system price(refer also to our sets). The state-of-the-art device platform uses the standard USB cable to charge the internal batteries(interchangeable) and read the data logger without the need for additional software or adapters. The logger is read conveniently likea USB 2.0 memory stick.Therefore, you have applications such as surface water monitoring, neutralisation processes or agricultural measurements ready tohand in a compact format.0 µS/cm...500 mS/cm (±0.5 % FS @ 25 °C) Salinity/PSU: 0.0…70.0 g/kgTDS: calculated from conductivity, adjustable calculation factor 0.40… 1.00Cell constant 0.3…1.6000 1/cm Temperature compens.:Off, linear (0.300...3.000 %/K),NLF (according to DIN EN 27888), Reference temperature: 20 °C or 25 °C (adjustable)Dissolved oxygen Measuring range:Oxygen saturation: 0.0…500.0 % sat Oxygen concentration: 0.0…50.0 mg/l Oxygen partial pressure: 0...1013 mbar O2(accuracy depending on sensor and calibration with flow > 20 cm/s, add.±1.5 % FS @ 25 °C, 100 % sat, O2) Temperature compens.: Automatically via connected sensorPressure compensation: Manual, automatic via int. sensor:500..1100 hPa ±4 hPa Salinity compensation: Manual PSU 0...70 g/kg Additional functions: Text-base user guidance (DE/EN),Charging via USB jack (3xAAA batteries integrated, exchangeable) Display:LCD (180 x 128 pixel), monochromatic, Adjustable backlight Interface:USB 2.0, Micro USB jack Calibration:pH: 1...5 point calibration (PHL buffer, DIN buffer)LF: Cell constant O2:: Water-saturated air Data logger:8 GB with FAT file system Alarm:Acoustic alerting (horn) Visual (red LCD background) Power supply:3x NiMh AAA (max. 750 mAh) Current requirement: On: approx. 75 mA in operation;Off: approx. < 0.1 mApi_gr_G7500_e_1.01 V1.01-00 1
