New Generation of Multiparameter Water Quality Monitors

To accommodate twice as many optical sensors as well as provide mechanical improvements, YSI has released new versions of its multiparameter water quality instruments, called sondes. The “version 2” (V2) features add up to a multiparameter sonde with the industry’s most versatile and complete sensor payload that can tolerate the most severe environmental conditions. YSI’s V2 sonde launch coincides with the launch of its ROX Reliable Oxygen Sensor and two versions of its Blue-green Algae Sensor (freshwater and marine).

A quick return to YSI Hydrodata will easily convert existing 6820, 6920, or 6600 sondes into V2 sondes for YSI customers. The first upgrades available are for the 6820 and 6920. These instruments measure up to 16 parameters simultaneously; the 6920 can run on batteries and log data. Both are suited for profiling or sampling in fresh, sea, or polluted waters.

A typical YSI 6-Series sonde, after a simple upgrade, can measure optical dissolved oxygen, blue-green algae, turbidity, chlorophyll, temperature, depth, conductivity, and pH.

For harsh fouling environments, YSI’s next generation optical sensors – dissolved oxygen and blue-green algae - feature an integrated wiper that prevents the impacts of biofouling, a corrosion-resistant titanium wiper shaft, and replaceable seals.

Commenting on the launch of the V2, YSI Regional Manager Darren Hanson says “YSI understands the challenges facing field scientists and technicians. All our sensors are field replaceable and perform extremely reliably for long deployments. Our upgraded instruments will provide them with the quality data they need at a total cost of ownership they can afford.”

Throughout 2006 YSI will continue to release upgraded versions of other multiparameter sondes in its 6-Series line.
