The YSI ProDSS (digital sampling system) handheld multiparameter meter provides extreme flexibility for the measurement of a variety of combinations for dissolved oxygen, turbidity, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium (ammonia), nitrate, chloride and temperature along with depth.
The YSI Professional Plus handheld multiparameter meter has been discontinued and YSI is no longer accepting orders for this instrument. We recommend ProQuatro or ProDSS handheld instruments as suitable replacements.
The Pro30 provides everything you need in a handheld meter that measures salinity, conductivity, specific conductance, total dissolved solids, and temperature. Rugged, simple and reliable.
The Pro20 provides everything you need in a handheld dissolved oxygen meter. Ruggedness, simplicity and reliability are the cornerstones of the instrument's design.
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 EC300A handheld conductivity instrument is part of the EcoSense® family of products. The EC300A offers convenient conductivity, specific conductance, salinity, total dissolved solids, and temperature with a super-stable, four-electrode conductivity cell for true field applications.

Capturing accurate data in fresh water, ground water and marine aquatic environments is easy with the versatile multiparameter EXO1 sonde. Ideal for estuarine, surface water or ground water applications.
The EXO advanced water quality monitoring platform includes the versatile multiparameter EXO2 sonde for oceanographic, estuarine, or surface water applications. Collect data to 250m with the advanced EXO2 sonde – contains six replaceable 'smart' sensors and a central wiper to clean biofouling.
Conductivity sensors from Aanderaa are compact, fully integrated sensors for measuring the electrical conductivity of seawater. Conductivity is a key parameter for in-situ measurements of several fundamental physical properties of seawater.
Note: This product is intended for sampling and profiling applications.
This sensor must be installed into an EXO Sonde to function (EXO1 | EXO2). Does not function on its own.
For long-term monitoring in fouling environments, please see our Wiped (C/T) sensor for the EXO2 platform.
The YSI 3200 is an innovative instrument that offers unmatched accuracy for ultrapure water analysis, multipoint calibration, and a high/low alarm for process applications.
This acoustic profiler features innovative development of the acoustic profiling capacity and an exceptional ability to collect high quality current information on moving and tilting moorings. Available as a self-recording instrument, it also integrates unique real time features to meet your application needs.
The single-point SEAGUARD® RCM series is a completely new generation of current meters based on the SEAGUARD® datalogger platform and the ZPulse® multi-frequency Doppler Current Sensor (DCS). SEAGUARD® Products are based on modern technology and are the basic modules of our underwater observatory. They may be used as a multi-parameter instrument in the sea and in freshwater and feature a modular plug-and-play architecture.
SeaGuard CTD Recorders may be used as a multi-parameter instrument in the sea and in freshwater and feature a modular plug-and-play architecture.
Mountable on a dam, pier, piling, or other stationary location, the 6950 offers user-programmable sample intervals with wireless transmission options. The YSI 6950 is compatible with all YSI EXO and 6-Series sondes equipped with depth, and comes with Profile Wizard software for easy set-up and deployment.
