Yosemitech Y4000 Multiparameter Sonde for Water Quality Monitoring adopts multi-in-one structure design, each single parameter sensor is RS485 digital probe and tightly inserted with the parent water surface, calibration data is stored in the single parameter sensor, which can be easily calibrated or replaced on site. Online monitoring of conventional 5 parameters (water temperature, pH/ORP, dissolved oxygen, conductivity, turbidity), can also monitor chlorophyll, blue-green algae, oil in water, etc., up to support a mother insert 6 probes, detect 7 parameters.
This Multi-Parameter Water Quality Probe also comes with a clean scraper, which can effectively clean the measurement end face, scrape out bubbles, prevent microbial attachment, and can calmly meet the monitoring needs of various water environment conditions such as sewage treatment, surface water, ocean and groundwater.
- Digital sensor with RS485 output and standard MODBUS protocol
- All calibration parameters are stored in the sensor, and each probe is equipped with a waterproof connector for easy plug-in and replacement
- Equipped with a self-cleaning brush for regular cleaning at set intervals to eliminate errors caused by bubbles or contamination, suitable for long-term unattended online monitoring
- The main unit can be connected to up to 6 probes, allowing for the use of various sensors such as dissolved oxygen, conductivity (salinity), turbidity, pH, ORP, chlorophyll, blue-green algae, and oil in water
- Each sensor can be replaced, calibrated, and maintained on site, providing flexibility and convenience to users
- Efficient acquisition algorithm with a whole machine response time of ≤30s, main unit integrated voltage abnormal shutdown, communication abnormal alarm, and cleaning brush abnormal alarm for convenient operation and maintenance judgment.
