For laboratory testing of BOD the 5100 provides unmatched ease-of-use and accuracy. The Professional Plus, Pro20, ProODO optical DO and DO200 handheld instruments quickly become laboratory instruments with a simple change of probes providing for convenient field and lab use.

Reliable, unattended DO monitoring is easy with the ROX wiped dissolved oxygen sensor which addresses the challenges of waste water when used with the 6820 V2 sonde. For biological processes to work efficiently, continuous monitoring of the slightest changes in DO is critical and the ROX sensor is ideal for this application.

		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.

		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.

		5000 / 5100 Laboratory Instruments for BOD Tests Both instruments feature: auto-calibration, large, graphic displays and low keypad profiles for maximum efficiency.

		pH10 Pen-style pH Tester Instrument The pH10 is part of the EcoSense® family of products. It's the perfect instrument for economical spot sampling of pH and temperature in many applications including wastwater, surface water, aquaculture, hydroponics, pools, and education.

		DO200 Dissolved Oxygen Meter The DO200 is part of the EcoSense® family of products. The DO200 dissolved oxygen meter offers fast dissolved oxygen response times in wastewater, surface water, and aquaculture applications.

		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.
