YSI 6-Series Water Quality Monitors

6-Series V2 Multiparameter Sondes for Long-term Monitoring

All Version 2 (V2) sondes accept the V2 optical sensors and have a rugged design for long term monitoring. Seven V2 sondes are offered with sensor payloads ranging from 5-9 sensors and multiple memory and power options to accommodate many different applications. In addition to the sensor options, YSI software calculates up to five additional parameters.

YSI 600 V2 sondes are designed for specific applications where a fewer number of parameters is required and size, ease-of-use, and price are of primary concern. All five 600 sondes offer a small and economical package for water quality monitoring, sampling and logging.
