VIKING-ISE300 Benchtop pH/Ion Meter
VIKING-ISE300 is a benchtop pH / ion meter for pH, mV, pX and ion concentration with a 7″ display, up to 5-point calibration, GLP memory, USB and RS-232 for routine ion analysis. It combines a 7.0″ backlit LCD, pH −2.00 to 20.00 (±0.01 pH), ion concentration from 1.000e-9 to 9.999e+9 (±0.5 %), ion calibration in up to 5 points, a 500-result memory (GLP), USB and RS-232 connectivity and IP54 protection.
Overview
Applications

Configuration checklist
- Ions: which ions and at what concentration (mg/L, ppm, mol/L).
- Sample matrix: interferences decide between direct reading and addition methods.
- Electrodes: combined ISE or half-cell with reference, plus pH / temperature.
- Documentation: GLP records, USB export or printer.
