Why Choose Viking ISE300?
🧪 Viking ISE300 pH/Ion Meter is a professional benchtop analyzer for high-accuracy measurement of pH, ion-selective electrodes (ISE), oxidation–reduction potential (ORP), mV and temperature. Built for laboratories, water utilities and research institutions, the ISE300 combines multi-parameter versatility with an intuitive touchscreen interface and GLP-compliant data handling.
Key benefits at a glance
With a high-contrast 7.0″ display for easy navigation and real-time data, the Viking ISE300 supports 1–6 point ISE calibration using methods such as direct reading, standard/sample addition and Gran plot. Multiple ISE units are supported (µg/L, mg/L, g/L, mmol/L, pX). Smart system tools simplify daily work: user/electrode/method/data management, audit trails and calibration reminders.
For applications from fluoride analysis and ammonium testing to routine pH stability checks, the Viking ISE300 pH/Ion Meter delivers outstanding accuracy and usability across drinking-water, wastewater and industrial labs. For related water analytics, see our Water Quality category on COLO.Science.
