Yosemitech Self-cleaning Sensor for Drinking Water
Hello, everyone! In this video, we will introduce our Portable Multi Parameter Meter. It can monitor water quality standard 5 parameters(water temperature, pH/ORP, dissolved oxygen, conductivity, turbidity), also can monitor chlorophyll, blue-green algae, oil in water and more.
Yosemitech Y4000 multiparameter water quality sonde 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 multiparameter meter 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.
