Advantages

The YSI ProDSS Water Quality Meter can measure parameters like DO (optical Dissolved Oxygen), pH, ORP, conductivity, specific conductance, salinity, TDS, resistivity, chloride, nitrate, depth, temperature and turbidity. The YSI ProDSS takes the advanced technology from the EXO series to make the best handheld available. This water quality monitoring instrument is rugged and reliable with intelligent, user-replaceable digital sensors that can be connected to any port and that are automatically recognised by the instrument and retain the calibration data. With optional GPS and depth the YSI ProDSS is completely customisable and with military specification connectors, IP67 waterproof, rubber over-moulded case and 1-metre drop tests, durability is ensured for longevity of sampling even in the harshest field conditions.

  • Smart, cost-effective and adaptable for the future.
  • High-impact body is built to record water quality parameters to depths of 250 meters.
  • Data is stored on-board the instrument for downloading to a laptop on completion of the monitoring sequence
  • YSI pedigree
