The Yamato WQC40-0-1B is a portable, high-performance multi-parameter water quality meter built around a 45 mm-diameter standard sensor module. It measures up to 9 items simultaneously and continuously — pH, electrical conductivity, turbidity, temperature, salt content, TDS (total dissolved solids), dissolved oxygen, seawater specific gravity, and ions including F⁻, Cl⁻, NO₃⁻, Ca²⁺, K⁺, and NH₄⁺. Rated for continuous measurement at water depths up to 100 m, it carries a 9999-data memory and is Modbus-compatible for integration into monitoring systems.

Application Profile
Water quality is inherently multivariate — pH, dissolved oxygen, conductivity, turbidity, and ion concentrations all move together, and reading them one probe at a time misses the correlations that tell the real story of a water body. A multi-parameter meter that logs up to 9 items simultaneously captures the full picture in one deployment, which is what makes it useful for environmental monitoring across diverse water environments — rivers, lakes, coastal and seawater, groundwater, and process or effluent water.
The 100 m depth rating and continuous-measurement design open up profiling applications: lowering the 45 mm sensor through a water column to map how oxygen, temperature, and conductivity stratify with depth — central to limnology, oceanography, and reservoir management. The onboard 9999-data memory supports unattended logging, and Modbus compatibility lets the meter feed a larger telemetry or SCADA system. Dissolved oxygen and turbidity in particular are workhorse indicators of aquatic health and pollution events, so a single portable unit covers a lot of field-monitoring ground.
Frequently Asked Questions
How many parameters can the WQC40-0-1B measure at once? Up to 9 items simultaneously and continuously — pH, EC, turbidity, temperature, salt content, TDS, dissolved oxygen, seawater specific gravity, and selected ions. (Some sensor configurations extend the parameter set further.)
Which ions can it measure? F⁻, Cl⁻, NO₃⁻, Ca²⁺, K⁺, and NH₄⁺, depending on sensor configuration.
How deep can it measure? It supports continuous measurement to a water depth of 100 m, enabling depth-profiling of a water column.
How much data can it store, and can it integrate with other systems? It has a 9999-data memory for logging and is Modbus-compatible for integration into telemetry or monitoring systems.
What sensor does it use? A 45 mm-diameter standard sensor module carrying the multi-parameter sensor set.
What is it used for? Environmental monitoring across rivers, lakes, coastal/seawater, groundwater, and process water — including depth-profiling for limnology, oceanography, and reservoir management.
