Multi Parameter Water Quality Meter: YSI ProDSS

The ProDSS is YSI’s latest (and we think best) handheld multi-parameter water quality meter. The all-new design uses digital sensors made of titanium that fit into any of the four slots on the probe and they remember their calibration information. The DSS has on board turbidity and the dissolved oxygen sensor uses optical luminescence for rapid and precise readings without the need to change membranes or add electrolyte. All sensors and cables are purchased separately so you can “build” the perfect instrument for your needs.

The readout is slim and rugged with a large backlit color display. All functions are menu driven. The DSS can log up to 100,000 readings and has site list capability. Data can be transferred using the USB port and the KorDSS data management software. The system looks and feels similar to the YSI556 software, even with the upgraded capability.

Our Standard Configuration includes:

  • ProDSS Meter,
  • 4 Meter Cable,
  • Flow Cell,
  • Sensors; Dissolved Oxygen (optical sensor!), Conductivity, Temperature, pH/ORP, Turbidity

3-Year Instrument Warranty, 2-Year Cable Warranty, Sensor Warranties Vary.
