Yosemitech’s Y4003 deep water multi-parameter sensor is designed with a sturdy and pressure-resistant structure and a self-developed titanium alloy watertight connector, and is specially tailored for deep water/well, ocean and other working conditions. Up to 6 sensors can be connected at the same time, and Yosemitech dissolved oxygen meter, pH/ORP, conductivity (salinity), turbidity, chlorophyll, blue-green algae, and oil in water sensors can be freely selected. The sensor probes are all made of titanium alloy and have good corrosion resistance.
The Y4003 multi-parameter machine with a cleaning brush can effectively clean the measuring end face, remove bubbles, and prevent microbial attachment. It can withstand up to 20 bar water pressure and work stably, and can handle the monitoring needs of various water environment conditions such as deep water lakes, ocean monitoring, underground drilling, and harsh wastewater effectively.

-RS485 output, standard MODBUS protocol, convenient for connecting to data acquisition platform and automatic water quality monitoring station.
-The main unit is equipped with 6 sensor interfaces of the same specification and 1 cleaning brush center interface, allowing for flexible connection to Yosemitech's probes.
-The main unit can be connected to up to 6 probes, which can freely choose sensors such as dissolved oxygen, conductivity (salinity), turbidity, pH, ORP, chlorophyll, blue-green algae, and oil in water.
-Equipped with a self-cleaning brush, this system conducts regular cleaning at set intervals to eliminate errors caused by bubbles or contamination. It is suitable for long-term unattended online monitoring.
-All calibration parameters are stored in independent sensors, and each sensor can be replaced, calibrated and maintained on-site.
-The multi-parameter whole machine is designed to withstand water pressure of up to 20 bar and operate reliably. It is specifically tailored for use in deepwater wells, oceans, and other challenging working conditions.
