Description
The M310F is a portable multi‑parameter water quality analyzer designed for field and on‑site water measurement. It integrates testing for pH, ion, conductivity and dissolved oxygen(DO) in one handheld unit. Built with IP65 waterproof housing, this meter adapts to complex outdoor test environments.
Equipped with a 3.5‑inch LCD screen, it supports auto‑read, timed‑read and continuous‑read measurement modes. Automatic temperature compensation delivers stable and accurate test results. It can store up to 500 sets of measurement data for each parameter and supports USB data communication for convenient data export and traceable records complying with GLP standards.
Multiple calibration options are available: up to 5‑point calibration for pH and ion, 1‑3‑point calibration for conductivity, plus air‑saturated water & zero‑oxygen calibration for dissolved oxygen. It features automatic electrode diagnosis, selectable buffer groups and measuring units, and supports advanced measurement modes including standard addition, sample addition and GRAN mode.
Suitable for environmental monitoring, water treatment plants, aquaculture, laboratory field sampling, river & reservoir water quality inspection and other water‑analysis scenarios.
