YSI 6920 Multiparameter Water Quality Meter

YSI 6920 Multiparameter Water Quality Meter

Pine Item #51680

The YSI 6920 is an economical logging system for long-term, in situ monitoring and profiling. It will log all parameters at programmable intervals and store 150,000 readings. At 15-minute intervals, it will log data for about 30 days.

A cost-effective logging unit rated at 200 feet, the YSI 6920 can monitor up to 14 parameters simultaneously, including oxygen with the YSI Rapid PulseTM stirring-independent sensor and turbidity sensor not affected by variations in ambient light that has a self-cleaning feature. A self-cleaning chlorophyll sensor may be installed instead of the turbidity sensor.


Non-volatile flash memory (384K) prevents data loss
