The YSI ProDSS - Digital Sampling System - is the ultimate water quality field instrument for sampling and profiling. With the ProDSS, we have answered our customer's demands to produce a truly rugged, reliable and smart multiparameter handheld instrument.
The Pro1020 provides everything you need in a handheld meter that measures dissolved oxygen and temperature along with either pH or ORP (redox). Rugged, simple and reliable. Measure pH or ORP, dissolved oxygen, and temperature.
The Pro1030 provides everything you need in a handheld meter that measures pH or ORP (redox) along with conductivity. Rugged, simple and reliable. Measure pH or ORP, salinity, conductivity, specific conductance, TDS, and temperature.
The ideal replacement for the discontinued YSI Model 85. The Pro2030 provides everything you need in a handheld dissolved oxygen meter that automatically compensates for changes in salinity values. Rugged, simple and reliable. Measure DO, salinity, conductivity, specific conductance, TDS, barometric pressure and temperature.
The new multi-parameter systems with intelligent, digital sensors for pH, dissolved oxygen (DO) and conductivity measurement revolutionize multi-parameter measurement:
The signal processing is completely located in the sensor, and the measuring signal is transmitted to the meter without interference and in a clearly identifiable manner via thin, highstrength cables. A wide range of sensors are available for virtually every application.
Up-to-date digital depth measurement with the WTW IDS system: A built-in barometric pressure and temperature compensated depth sensor combines dissolved oxygen, pH or ORP and conductivity measurements with accurate depth readings.
Swap one smart sensor for another with the ProSwap digital water quality meter. Featuring built-in temperature and optional depth sensors, ProSwap can transform into whatever you need it to be: a purpose-built turbidity meter or a high-accuracy optical DO meter; a spot sampling pH meter or a profiling conductivity-temperature-depth system. It can even handle beach monitoring for harmful algal blooms.
The ProQuatro handheld multiparameter meter measures a variety of combinations of dissolved oxygen, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium (ammonia), nitrate, chloride and temperature. Also a very powerful lab instrument for BODs, pH and ORP.
