Wastewater management, whether municpal, industrial or from other sources, encompasses a broad range of efforts that promote effective and responsible water use, treatment, and disposal and encourage the protection and restoration of our nation's watersheds.

If wastewater was not properly treated it could easily cause negative impacts on the environment and human health.

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.

For multiparameter continuous water quality monitoring and control in your wastewater facility consider the YSI IQ SensorNet 2020 XT. Measure multiple locations with up to 20 sensors.

		6820 V2 Compact Sonde for Field Sampling The YSI 6820 V2 is a cost-effective data sonde for profiling and spot-checking water quality in rivers, lakes, wetlands, wells, estuaries, and coastal waters.

		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 "We are very pleased with the convenience, usability, and ruggedness of the ProODO; and highly recommend it to anyone needing to monitor dissolved oxygen." The YSI ProODO^TM handheld DO meter provides extreme durability for measuring dissolved oxygen with optical, luminescent based technology for field or lab.

		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 "YSI did a great job on this design. Our staff of about 20 people consists of old veterans to recent college grads, and not one so far has had a negative comment." 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.

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

		BOD Analyst Pro™ Desktop Software Automatically calculate BOD/CBOD values with the BOD Analyst Pro desktop software.

		pH10A Pen-style pH Tester Instrument The pH10A 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.

		IQ SensorNet 2020 XT Improve Operational Efficiency with Continuous Data With an easily scalable solution, the 2020 XT allows for the connection of up to 20 sensors. This modular plug-and-play system allows you to monitor the water quality in your wastewater system continuously and accurately. "We haven't had any issues and are very happy with it. Installation and setup are very user friendly."

		IQ SensorNet 182 Models Improve Operational Efficiency with Continuous Data With an easily scalable solution the 182, 182 XT, and 182 XT-4 allow for the connection of 1-4 sensors depending on which terminal you choose. Add sensors at any time and at any location or change them out with ease. This completely modular plug-and-play system allows you to monitor the water quality in your wastewater or aquaculture system continuously and accurately.
