LaMotte TRACER Pocket Water Quality Testers (Dissolved Oxygen, EC, TDS & Salinity)
The LaMotte TRACER series represents a breakthrough in handheld water analysis, offering laboratory-grade digital precision in a rugged, pocket-sized format. Designed for professionals who require rapid results in the field, these meters utilize sophisticated sensor technology to deliver fast, numerical results directly on a high-contrast LCD without the subjectivity of colour matching. The Dissolved Oxygen (DO) TRACER is particularly notable as the world’s first pocket ISE with integrated temperature compensation, delivering accurate mg/L or % saturation readings in less than 60 seconds. For multi-parameter monitoring, the EC/TDS/Salt TRACER provides a versatile 3-in-1 solution, allowing users to toggle between conductivity, total dissolved solids, and salinity measurements with a single sensor.
Built to withstand the rigours of field work and industrial testing, every TRACER meter features a waterproof, submersible housing and an ergonomic design that fits comfortably in the hand. The series is engineered for maximum efficiency, featuring a high-contrast LCD that simultaneously displays the primary parameter alongside sample temperature, an analogue bar graph for trend visualization, and an internal memory for up to 25 labelled readings. Whether you are managing aquaculture health, monitoring industrial cooling towers, or performing environmental research, the LaMotte TRACER series ensures that "Quick, Accurate, and Digital" professional-grade water testing is always portable and accessible.
