From June 4th to 6th, 2025 WieTec will take place at NECC, Shanghai. Yosemitech will be at booth 5.1H707, showcasing a range of water quality monitoring sensors, handheld meters, universal controllers, and more. Looking forward to meeting you here!

Yosemitech Products:

Y4003 Multi-parameter Sonde for Deep Water

Y4003 online deep-water multi-parameter sensor is designed for marine and deep-water monitoring. It features a robust, pressure-resistant structure with a self-developed Ti connector. The main unit has 6 uniform sensor interfaces, supporting up to 6 sensors (e.g., DO, pH/ORP, conductivity, turbidity, chlorophyll, BGA, OIW, depth). Y4003 sonde can withstand up to 20bar of water pressure and operates stably in various water environments, including marine, deep lakes, underground drilling, and harsh wastewater.

Y507-A Handheld Dissolved Oxygen Meter

Y507-A dissolved oxyegn meter uses internationally advanced fluorescence lifetime technology.   Based on the principle of quenching active fluorescence, it measures dissolved oxygen without consuming oxygen, has no flow rate limit, requires no preheating or electrolyte, and needs minimal maintenance or calibration.   Its response time (T90) is just 20 seconds, exceeding national standards.

Y551-B/C Self-cleaning COD Sensor

Y551-B/C UV254 COD sensor, based on ultraviolet absorption principles and improved from its predecessor, is more compact and integrates a built-in cleaning brush for easier installation and operation. It requires no reagents, avoids pollution, and supports long-term online water quality monitoring while being economical and environmentally friendly. Featuring an internal turbidity detection light source, it automatically compensates for water turbidity interference and ensures stability during extended use with its automatic cleaning brush.

Y560-A Online Ammonium Sensor

Y560-A ammonium sensor requires no reagents, is environmentally friendly, and supports real-time online monitoring. It includes an ammonium ion electrode, a pH electrode, and a reference electrode (optional potassium ion electrode). During measurement, it automatically compensates for pH and temperature for improved accuracy. Y560-A can be directly installed via immersion, offering cost-effective, fast, and convenient operation compared to traditional analyzers. Equipped with a self-cleaning brush, it prevents microbial adhesion, extends maintenance intervals, and ensures reliability. It features RS485 output with Modbus support for easy integration.

Y4000 Online Multi-parameter Sonde

Yosemitech Y4000 online multi-parameter sonde features a compact, integrated design. Each single-parameter sensor is an RS485 digital probe connected to the main unit, with calibration data stored locally for easy on-site calibration or replacement. It supports real-time monitoring of up to 7 parameters, including temperature, pH/ORP, DO, conductivity, turbidity, chlorophyll, BGA, and OIW. The sonde can connect up to 6 probes and includes a built-in cleaning brush to remove bubbles, prevent microbial adhesion, and ensure accurate measurements. Suitable for various water environments such as wastewater treatment, surface water, marine, and groundwater.
