pH meters are one of the most common analysers in use today on water treatment and process plants and yet online pH meters cause continual problems for their operators. What is needed is a reliable, self-cleaning, self-calibrating pH meter for a reasonable cost. That is exactly what you get with the CRIUS 100 and CRIUS 100+ process pH analysers.

The pH sensor at the heart of the Process Instruments online pH meter is a K-series polymer filled glass electrode. This pH electrode is far superior to many pH electrodes on the market and is designed for a long life, low drift and reliability. Unlike many pH analysers, you don't need to search through hundreds of pH electrodes to find one that works in your process as the K-series electrode works in all environments from pH 2 to 12 and in conductivity from 0µs to 10,000µs.

Auto-calibrating pH meters are few and far between and often have limitations or command extraordinarily high prices. The CRIUS 100 self-calibrating pH meter takes away the requirement for continual calibration and re-calibration of the pH meter by operators as it utilises the K-series pH electrode and it can auto-calibrate at user defined intervals using 3 buffer solutions at pH 4, 7 and 10. Not only will the CRIUS 100 pH meter clean itself and auto-calibrate, but will calculate a degree of confidence in its own calibration and let you know if its confidence is low.

Self-cleaning is a becoming a pre-requisite for many online analysers and online pH analysers are no exception. Self-cleaning and self-calibrating online pH meters can often pay for themselves very quickly through less operator time and greater up-time.
