Model WQC-24P

Multiparameter Water Quality Meter
(8~11 parameters plus water depth available)
The Model WQC-24P is the latest development in DKK-TOA’s range of multi-parameter water quality meters. The very latest technologies combined with more than 50 years experience have resulted in a compact, high performance and robust water quality monitoring system

The 45mm outer diameter sensor probe can provide measurement of up to 11 parameters simultaneously out of a total of 17 available parameters. The instrument also features an interface port for connection to a Global Positioning System (GPS), Local Area Network (LAN) printer or other communication peripherals.


  •     Standard 8 Parameters
  •     Max 11 Parameters out of 17 Available.
  •     Optional water depth sensor.
  •     Independent Sensor Memory/Logger.
  •     RS232 Interface for External Peripherals.
  •     Waterproof Meter (IP-67, Submersible).
  •     GPS Receiver Compatible
  •     Base configuration includes pH, DO. Turbidity, Temperature, Conductivity, Salinity, Total Dissolved Solids, and Specific gravity.
  •     Options for ORP, specific ions including nitrate, chloride, fluoride, calcium, potassium, and ammonia ion and chlorophyll.
  •     Measurement to a depth of 100 Meters is possible (standard 8 parameter probe).


Multiple Parameter Combinations:
The sensor probe can measure up to 11 parameters out of 17 available (pH, ORP, DO, EC, Turbidity, Temperature, Salinity, Total dissolved solids, Specific gravity and Water depth plus Chlorophyll and Ions of NO3 -, Cl-, F-, Ca2+, K+, NH4 +).

Newly Developed High Performance Sensors:
pH sensor is equipped with our patented “Strong” electrode which is far more robust than conventional glass electrodes while retaining excellent sensitivity. The DO sensor also has a patented design which allows it to function even under non-flowing conditions. Conventional DO electrodes require continuous sample flow to operate correctly.

Compact Sensor Probe:
45 mm outer diameter sensor probe fits into a 2-inch well.

Robust Sensor Probe:
Resisting Sea water & High Pressures. Sensor probe facilitates measurements as far as 100 meters below the water surface and up to max pressure of 1 MPa (excluding ion sensors).

Data Logging Storage Capacity:
Exceeds one month. Built-in memory stores measured data for 35 days of continuous measurements (based on measurement every 15 minutes). The probe section can be disconnected from the meter and will continue to measure and record data. This data can be retrieved by the meter when the sensor cable is reconnected and then transferred to a personal computer in csv format.

Flexible Interface Port:
Compatible with Global Positioning System (GPs)
An interface port is available for connection to GPs, Printer, RS-232C, LAN, Cellular phone or other data communication peripherals
