The YSI 9300 and YSI 9500 are economical photometers in small packages for any application. These portable photometers allow you to easily take readings directly in the field for 100+ parameters.
The YSI Professional Plus handheld multiparameter meter provides extreme flexibility for the measurement of a variety of parameters such as DO, conductivity, specific conductance, salinity, resistivity, total dissolved solids (TDS), pH, ORP, pH/ORP combination, ammonium (ammonia), nitrate, chloride and temperature.
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.
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 YSI 6600 V2 data sonde is the most comprehensive water quality monitoring equipment available with simultaneous measurement of conductivity (salinity), temperature, depth or level, pH/ORP and...
The advanced monitoring platform EXO includes a multi-item EXO2 zone, which can be applied to oceanographic, stormwater or surface water applications. The advanced EXO2 sonde collects data up to 250m. - Consists of six interchangeable 'smart' sensors and a central wiper to clean bio attachments.
Each TruLine ISE features an integrated reference. This eliminates the need for a separate reference half-cell when measuring ion concentration and is more convenient. Each ISE can be refilled with reference/electrode filling solution, extending the life of each ISE. The electrodes also feature a double-junction reference for optimum performance in the lab.
Reagent free, ion selective measurement of ammonium and nitrate with automatic compensation of potassium/chloride with the VARiON® Plus 700 IQ.
These especially stable electrodes ensure long operation times and a simple cleaning method. To measure, simply install the respective electrode into the IQ Sensor Net - everything will take place automatically.
Measure pH, ORP, and ion activity with the TruLab 1320 dual channel instrument by choosing from our wide selection of electrodes.
The YSI 6951 Pontoon Vertical Profiling System offers user-programmable sample intervals, redundant error recovery logic that detects unexpected activity and recovers automatically, and is compatible with all YSI EXO and 6-Series sondes equipped with depth.
