OVERVIEW

🧪 The VIKING-ISE510 pH/Ion Meter is a portable, IP65-rated analyzer for pH, ISE, ORP/mV, and temperature. A bright 4.3″ touchscreen with simple menus keeps daily work fast. As a result, setup and calibration are quick and consistent. In addition, built-in GLP tools keep your data organized and traceable. For related instruments, see our Water Quality collection on COLO.Science.

The instrument features a smart OS with user, calibration, electrode, method and data management (GLP) plus logs. It supports multiple reading modes: auto-read, timed-read, and continuous-read. Temperature compensation is available as ATC or MTC, and the Auto-Hold function locks the endpoint for easy recording.

With IP65 waterproof housing, the ISE510 is built for demanding field and outdoor measurements. It stores up to 1000 data sets per parameter (GLP-compliant) and offers USB communication for data export. Whether you’re monitoring drinking water, wastewater, or industrial processes, the VIKING-ISE510 delivers reliable performance.
