Multi Parameter Water Quality Meter, WQC-24

Simultaneous measurement of up to 11 parameters including pH, DO, turbidity, conductivity, temperature, and salinity.

The WQC-24 Water Quality Checker is a multi-parameter portable field instrument and sonde by DKK-TOA for measuring up to 11 of 17 available simultaneous water quality parameters.

This advanced technology allows for a highly compact, high performance probe which can measure pH, Temperature, Dissolved Oxygen, Turbidity, Conductivity, and Salinity. The sensor can be used as a remote data logger / Sonde for up to 35 days of monitoring at 15 minute intervals.

The standard probe design, with a 45mm (less than 2 inch) outer diameter, can provide measurement 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 PC interface via standard RS-232.

The new WQC-log software control package allows for data transfer and control with a PC in a standard spreadsheet configuration.

Features:

  • A remote sonde/sensor for 35 day data memory storage when using 15 minute interval logging function.
  • GPS interface port or RS-232, LAN, Cell phone, or other data communications is standard. Latitude and longitude coordinates can be stored with measured data.
  • The Standard sensor can measure up to 11 simultaneous parameters out of 17 available parameters.
  • pH, DO. Turbidity, Temperature, Conductivity, Salinity, Total Dissolved Solids, and Specific gravity.
  • Options are available for ORP, specific ions including nitrate, chloride, fluoride, calcium, potassium, and ammonium ion, chlorophyll and Depth.
  • Measurement to a depth of 100 Meters is possible.
