E+H pH, ORP, DO and COD Measuring Systems
We supply the complete E+H range of water analysis instruments: pH meters, ORP (redox) meters, dissolved oxygen meters and COD analyzers, together with the matching transmitters, electrodes, cables and immersion assemblies.
Transmitters
- Liquisys CPM223: panel-mount pH/ORP transmitter with modular design, suitable for analogue and Memosens digital sensors
- Liquisys CPM253: field housing pH/ORP transmitter in PC/ABS, 247 x 170 x 115 mm
- High operating safety: fault contact and error current can be defined to suppress unwanted alarms
- Automatic cleaning control to cut maintenance cost
- Overvoltage (lightning) protection and calibration plausibility check
- Language selectable display, measured value and temperature at the same time
Electrodes and sensors
- pH electrodes: CPS11D-7BA21, CPS11D-7AA21, CPS41, CPS71D, CPS91D
- ORP electrodes and combined pH/ORP probes
- Dissolved oxygen sensors: COS41, COS61, COS61D, COS71
- Conductivity sensors: CLS12, CLS15, CLS21, CLS50
Applications
- Drinking water, cooling water, well water and process water
- Wastewater treatment and neutralisation control
- Chemical processes, pulp and paper, plastics and chemical industry
- Power plants, including flue gas desulphurisation scrubbers
- Food, beverage and life science applications
Please tell us the measuring point, range and cable length and we will quote the exact configuration.
