ProDSS Multiparameter Digital Water Quality Meter
OVERVIEW
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.
The YSI ProDSS (digital sampling system) handheld multiparameter
meter provides extreme flexibility with two main cable options.
Choose between the fully loaded 4-port cable assembly outfitted
with any four DSS sensors (with depth or no depth) or the ODO/CT
probe and cable - where you get accurate DO measurements every time
with an optical dissolved oxygen sensor with an inline conductivity
sensor, allowing for real-time salinity compensation.
FEATURES
* 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.
