The 803PS Water Quality Sonde

The 803PS Sonde is an immersible multi-electrodes measuring platform, which can accommodate up to eight different electrodes simultaneously. It fits easily into a 4-inch (100 mm) borehole and can be used to monitor water quality at depths up to 100 meters.

803PS Sonde Electrodes

The following electrodes are designed specifically to fit the 803PS Sonde
Temperature sensor -5 °C to +50 °C which is a standard fitting.

830PH ...pH level 0 to 14 combination electrode.

834PH ...Redox/ORP, range ±800mV

840US ...Conductivity 0.5µS/cm to 100mS/cm. Salinity/TDS 0 to 60ppt

850OX ...Dissolved Oxygen 0 to 20ppm, 0 to 200% saturation

810TU ....Turbidity/TSS 0.2 NTU to 4000NTU

803PD ....Depth measurements 0 to 100 meter

860IS .....Ammonium ISE (Contact LMS water for ISE sensors)


Features
Up to eight different chemistry electrodes for measuring water quality can be fitted at one time.
The 803PS Sonde contains its own microprocessor and control electronics, so the cable from the Sonde to the WP4007 (data logger) supplies only the power and digital interface between the instrument and the Sonde.
The Sonde can withstand 300ft (100m) water depth, and can be used to measure estuaries, lakes, rivers and effluent.
