Introduction
This portable meter features a 4.3-inch high-contrast LCD touchscreen and an intelligent operating system for full management of users, calibration, electrodes, methods, data, and logs. It supports automatic, timed, and continuous measurement modes, with both automatic and manual temperature compensation for precise results. The auto-hold function detects and locks stable readings for reliability. GLP-compliant storage allows up to 1,000 data sets per parameter, with built-in tools for reviewing and recalculating measurements. Designed for field use, the instrument offers IP65 waterproof protection, USB connectivity, automatic power-off to conserve battery, and dissolved oxygen capabilities including calibration with air-saturated or zero-oxygen water, automatic barometric pressure compensation, manual salinity adjustment, and selectable pressure units.
