YSI 6600V2 Multi Parameter Water Quality Monitoring Instrument

Multi parameter water quality monitoring instrument: small in size, strong in function, suitable for multi-point sampling, fixed-point data acquisition, long-term continuous online monitoring, and profile analysis of different water bodies
Fast pulse dissolved oxygen sensor: YSI unique technology, readings are not easily affected by contamination, effectively extending maintenance cycles, and 30 day calibration drift is less than 5%
Dissolved oxygen sensor has no flow rate dependence, does not require stirring, and can truly reflect the supersaturation phenomenon of static ecological water bodies
The optical sensor comes with a cleaning brush, which effectively eliminates bubbles, reduces the impact of contamination on measurement, and is not affected by external light interference
The on-site monitoring provided by chlorophyll sensors can detect the chlorophyll status of phytoplankton, which is used to predict algal growth and water nutrition status
Except for the depth sensor, all other probes can be replaced, calibrated, and maintained on site
Non volatile memory: data will not be lost due to power failure and can store up to 150000 readings
RS-232 and SDI-12 interfaces: can connect to most data recording and acquisition platforms, water quality automatic monitoring stations, and telemetry systems
EcoWatch data analysis software: real-time monitoring, data processing, statistical analysis, report generation, both Chinese and English versions are free and randomly gifted
