YSI Pro DSSPro DSS Intro

The YSI ProDSS (digital sampling system) is a portable water quality multiparameter instrument for the measurement of several critical parameters - dissolved oxygen (optical), total algae, turbidity, pH, ORP, conductivity, specific conductance, salinity, TDS, resistivity, TSS, ammonium, ammonia, chloride, nitrate, depth (optional), temperature and GPS coordinates.

Designed for use in applications such as surface water, groundwater, coastal/estuarine, aquaculture, and wastewater, the rugged and reliable ProDSS allows for the measurement of water quality parameters with digital sensors. The ProDSS water quality meter uses smart sensor technology that allows sensors to be automatically recognized by the handheld while retaining calibration data.

An easy-to-read backlit color display, large memory capacity, simple calibration procedures, rechargeable battery and powerful data management program (KorDSS) all help to make your sampling experience more convenient.

The optional GPS and depth along with a wide range of cables and sensors (sold separately) allows for complete customization of the ProDSS. Military spec connectors, IP-67 waterproof rating, rubber over-molded case and 1-meter drop tests ensures durability to provide years of sampling even in the harshest field conditions.

Not only have we answered our customers demands for a handheld instrument that can measure turbidity, the ProDSS can also measure depth (optional) in addition to pH, ORP, optical DO, conductivity, and GPS coordinates (optional).

There are many options when ''building'' a ProDSS instrument. In addition to the ProDSS 4 port cable and the ODO/CT probe and cable assembly, the ProDSS will also work with YSI ProODO sensor/cable assemblies to provide a DO only instrument. It's also capable of using the ProOBOD optical BOD probe for use in the lab for BOD measurements.

The ProDSS is a true field instrument. The titanium smart sensors (4 port cables) can easily be replaced in the field and our durable MS (Military Spec) locking bayonet-style cable connector ensures quick cable connection. A rugged and waterproof (IP-67) rubber over-molded instrument casing provides protection from the demands of field sampling.

Some sensors are EPA approved for drinking water and wastewater compliance reporting.

Cables and sensors are sold separately.

Note: A conductivity/temperature sensor (626902) must be installed in a ProDSS 4 port cable for accurate temperature compensation and measurement of all parameters except turbidity and TSS.

All ProDSS instruments include a rechargeable lithium-ion battery (pre-installed), hand strap, USB cable for charging the ProDSS battery and for connection to a PC, universal AC charger, cable for connection to a USB memory stick, ProDSS quick start guide, and USB memory stick containing KorDSS software and a digital copy of the user manual.
