MODEL & PARAMETERS
| Model | Measured parameters | Display & operation |
|---|---|---|
| VIKING-PH310F | Measures pH, mV and temperature. Supports 1–5 point calibration with automatic standard recognition and selectable buffer groups (NIST, DIN, GB, USA). Automatic electrode diagnostics display pH slope and offset, helping the user decide when cleaning, reconditioning or replacement is required. |
Equipped with a 3.5″ backlit LCD and intuitive menu structure. Offers Auto-Read (Fast/Medium/Slow), Timed-Read and Continuous-Read modes with Auto-Hold endpoint detection. IP65 protection, 500 data sets per parameter with GLP-ready logging, USB output and configurable auto power-off make the VIKING-PH310F a compact, reliable pH/mV meter for routine and field applications. |
