OVERVIEW

📱 VIKING-ISE310 Portable pH/Ion Meter is a rugged, field‑ready instrument designed for accurate measurement of pH, ion‑selective electrodes (ISE), mV, pX and temperature. Combining a 4.3″ color touchscreen with low‑drift electronics and intuitive operation, it is ideal for environmental monitoring, industrial water testing, and on‑site analysis.

The meter supports up to 5‑point calibration for pH and ISE with automatic buffer recognition (NIST, GB, USA, DIN). Ion measurement includes direct reading, standard/sample addition and GRAN methods, with units in mol/L, mmol/L, g/L, mg/L, μg/L, ppm and ppb. Built‑in methods cover common ions (F⁻, Cl⁻, Br⁻, NO₃⁻, NH₄⁺, K⁺, Na⁺, Ca²⁺, Cu²⁺, Pb²⁺, Ag⁺, etc.) plus user‑defined options.

With GLP‑compliant data storage for 1000 groups, multiple reading modes (auto, timed, continuous), and an IP65 splash‑proof enclosure, the ISE310 is built for demanding fieldwork. It is supplied with a pH electrode, temperature probe, calibration buffers, silicone protective case, and wrist strap – a complete solution ready to use.
