VIKING-M510A Portable Multi-Parameter Meter
Overview
VIKING-M510A by COLO.Science measures pH, ion-selective electrodes (ISE), conductivity (EC) and temperature. It also supports mV/ORP and pX, and it calculates resistivity, TDS and salinity. In short, it is easy to use, fast and highly precise.
Moreover, the 4.3″ color touchscreen speeds up configuration and daily work. Therefore, routine testing becomes quicker and more consistent. In addition, the IP65 housing enables reliable field operation.
General Features
- Multi-reading: auto-read, timed-read, continuous-read.
- Automatic/Manual temperature compensation (ATC/MTC).
- Auto-hold endpoint lock; clear Reading / Stable / Locked prompts.
- GLP data: up to 1000 sets per parameter, with data review/compare/recalculate.
- User, calibration, electrode, method and log management.
- USB communication; auto power-off; factory reset.
- IP65 portable design for field/outdoor measurements.
