YSI Groundwater Applications

YSI groundwater instruments can be used with flow cells to easily pump water through the cell to provide continuous flow past the probes preventing placing instruments into the well. Measure dissolved oxygen, level, pH, ORP, conductivity, salinity, temperature or turbidity easily and accurately.

		6920 V2 Compact Sonde for Unattended Monitoring The YSI 6920 V2 sonde is an economical logging system, ideal for long-term in situ monitoring and profiling. Two versions: 6920 V2-1 has one optical port, conductivity/temperature port, Rapid Pulse Dissolved Oxygen port, pH/ORP port, and 3 ISE ports 6920 V2-2 has 2 optical ports, conductivity/temperature port, pH port, and one ISE port.

		6820 V2 Compact Sonde for Field Sampling The YSI 6820 V2 is a cost-effective sonde for profiling and spot-checking in rivers, lakes, wetlands, wells, estuaries, and coastal waters. Two versions are available: 6820 V2-1 has one optical port, conductivity/temperature port, Rapid Pulse DO port, pH/ORP port, and 3 ISE ports 6820 V2-2 has 2 optical ports, conductivity/temperature port, pH port, and one ISE port.

		600XL V2 and 600XLM V2 Small Packages - Economical Sampling or Logging Both the YSI 600XL V2 (sampling) and the YSI 600XLM V2 (logging) offer economical solutions in small packages for surface water and ground water applications. Both models easily fit into 2-inch wells and measure a range of fundamental parameters, including oxygen - with the YSI ROX™ optical dissolved oxygen sensor - and level, using a highly-accurate vented sensor.

		600QS The Quick Solution to Handheld Sampling Combined for convenience, the YSI 650 MDS display-datalogger and the YSI 600R sonde allow you to collect 11 parameters simultaneously in real time.

		600R Water Quality Sampling Sonde The YSI 600R provides water quality sampling in a small package for surface water and ground water applications. With a diameter of less than two inches (4.2 cm), the 600R easily fits into wells.

		Level Scout® Level and Temperature Accurate measurements, rugged design, and easy data management make the Level Scout ideal for groundwater monitoring, long-term surface water studies, resource management, aquifer/pump tests, Soil Vapor Extraction, wastewater intake monitoring and leachate monitoring.

		Professional Plus Handheld Multiparameter Instrument The YSI Professional Plus handheld multiparameter meter provides extreme flexibility for the measurement of a variety of combinations for 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.

		ProODO Handheld Optical Dissolved Oxygen Instrument The YSI ProODO^TM handheld DO meter provides extreme durability for measuring dissolved oxygen with optical, luminescent based technology for any field application or lab BODs.

		Pro20 Lab / Field Dissolved Oxygen The Pro20 provides everything you need in a handheld dissolved oxygen meter. Ruggedness, simplicity and reliability are the cornerstones of the instrument's design.

		Pro2030 Field Dissolved Oxygen / Conductivity The Pro2030 provides everything you need in a handheld dissolved oxygen meter that automatically compensates for changes in salinity values. Ruggedness, simplicity and reliability are the cornerstones of the instrument's design. Measure dissolved oxygen, salinity, conductivity, specific conductance, total dissolved solids (TDS), barometric pressure and temperature.

		556MPS Handheld Multiparameter Instrument Rugged, reliable and waterproof, the YSI 556 MPS (Multiprobe System) combines the versatility of an easy-to-use, easy-to-read handheld unit with all the functionality of a multiparameter system.

		9300 / 9500 Photometer Waterproof, rugged, easy to use photometers 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.
