OpH218 Benchtop pH Meter – Ag / AgCl Non-Combined Pack

This non-combined pack is composed of the OpH218 pH meter from OrigaLys, a non-combined pH electrode, an Ag / AgCl reference electrode and two cables to connect the electrodes to the pH meter.

The use of the OpH218 has been specially designed for teaching. With a 5-year warranty (excluding consumables), it will adapt perfectly to an existing fleet of pH meters because its interface is similar to those of the old Radiometer pH meters.

Elements included in the non-combined Calomel Pack:

  • An OpH218 pH meter
  • One uncombined pH electrode
  • BNC-S7 cable (pH electrode)
  • BNC-S7 cable (pH electrode)
  •  A Banana-S7 cable (reference electrode)

OrigaSens – Temperature Sensor

pH Electrodes

The pH measurement of an acidic, neutral, basic solution is based on the potential difference between a glass electrode and a reference electrode (Hg, Hg / HgO or Ag / AgCl). This signal is proportional to the activity of the H + ions, according to Nernst’s law.

The combined pH electrode brings together, in one body, a glass electrode and a reference electrode.

Reference Electrodes

A reference electrode has a constant potential regardless of the measurement conditions. The main difference between reference electrodes is the nature of the reference element and the type of electrolytic junction. OrigaLys offers you reference electrodes with Calomel (Hg), Mercuric Oxide (Hg / HgO) and Silver / Silver Chloride (Ag / AgCl).

Temperature Probe

For pH and ionic concentration measurements by selective electrodes and for conductivity measurements, the use of a temperature probe is recommended because the result depends on the measurement temperature.
