The Multiparameter Waterproof Meter offers professional-grade versatility for analyzing water quality in field and laboratory environments. Designed for environmental monitoring and educational use, the instrument measures pH, oxidation-reduction potential (ORP), conductivity, dissolved oxygen, salinity, resistivity, and temperature with precision and stability. Its digital multi-sensor probe transmits data directly to the handheld meter, minimizing electrical interference for consistently reliable results. A 20 m (65.6 ft) cable allows access to wells, reservoirs, and large field sampling sites, while automatic calibration and temperature compensation ensure fast, dependable measurements. Built to withstand rigorous field use, the system's IP-rated waterproof housing and impact-resistant design make it ideal for hydrology, limnology, and environmental testing applications. Data can be stored internally and easily exported via USB, supporting long-term monitoring or coursework-based research.

To maintain sensor accuracy, the Spare Dissolved Oxygen Membrane Caps (sold separately) provide easy, tool-free replacement of worn membranes. Each pre-tensioned cap maintains consistent oxygen diffusion, ensuring stable and precise DO readings across multiple testing sessions. These accessories simplify maintenance and extend the lifespan of the dissolved oxygen probe, helping educators and researchers sustain high-quality data collection year after year. Together, the Multiparameter Waterproof Meter and its compatible maintenance accessories deliver a comprehensive water-analysis platform that combines durability, precision, and ease of use for both professional fieldwork and science education.

Accessories information: Spare dissolved oxygen membrane caps (set of 5). Replacement membranes designed for the meter's dissolved oxygen probe. Each cap features a pre-tensioned, oxygen-permeable surface for accurate readings and quick, tool-free installation during maintenance.
