YSI ProDSS (Digital Sampling System)

A handheld multiparameter meter that takes a range of smart sensors, for detailed water quality sampling across a site.

Price range: $230.00 through $5,600.00 ex GST

Product Information

Key Features

  • Four smart sensor ports on one cable — any ProDSS sensor works in any port, is recognised automatically and carries its own calibration data
  • Optical dissolved oxygen by luminescence lifetime method: 0 to 50 mg/L, ±1 % of reading to 200 % saturation, with a user-replaceable sensor cap and no membranes
  • pH 0 to 14 (±0.2), ORP −1999 to 1999 mV (±20 mV), conductivity 0 to 200 mS/cm (±0.5 %) and turbidity 0 to 4000 FNU
  • A conductivity/temperature sensor (626902) must be fitted in the cable for accurate measurement of all parameters
  • Cable assemblies from 1 to 100 m, with or without a depth sensor, and optional GPS on the handheld
  • Rechargeable lithium-ion battery, colour display, more than 100,000 data sets of memory and KorDSS software included
  • IP-67 waterproof with military-spec connectors, rubber over-moulded case and 1 metre drop tested
  • Choosing your model: build it in three steps — pick the handheld (with or without GPS), pick a 4-port cable assembly by the depth you need to reach (1 m tank-side, 4 m raceways and sumps, 10 m deep tanks and intakes), then add the sensors, always including the conductivity/temperature sensor.
