Benchtop Ion / pH / mV Meter, Five-Point Calibration

Benchtop ion meter that reads ion concentration directly from an ion-selective electrode over two to five calibration points, and also measures pH, ORP and temperature.

Typical applications

  • Fluoride in drinking water and toothpaste
  • Nitrate in water, soils and fertilisers
  • Environmental monitoring
  • Food and pharmaceutical testing
  • pH and ORP measurement

Worth knowing before you order

The most important line in the accessories list is what is not in it: the meter ships with a pH electrode, stand, ATC probe and pH buffers, but no ion-selective electrode. The fluoride and nitrate ISEs are catalogued as optional accessories, and until one is fitted this is a pH and mV meter. Order the ISE, its standard solutions and its ionic strength adjustment buffer (TISAB or ISAB) at the same time — all three are consumables, and the ISE membrane has a service life that is shorter than the meter's by a wide margin. Ion calibration runs low concentration to high, over two to five points, so buy standards that bracket the concentration you expect.
