pH Meter – pHSense

• Remote Sites
• Cooling Towers
• Food Preparation
• Paper Mills

Anywhere you have a requirement to measure pH is a suitable application for the pHSense. The pHSense online pH meter range is particularly suited to working in sites where reliability and ease of use are most important.

AutoFlush – As described elsewhere, the pHSense can come equipped to automatically clean itself at user defined intervals with all the benefits of no operator intervention. The AutoFlush is particularly useful in food preparation, pulp and paper, and many applications where there is likely to be a build up of solids in the sample.

Multi-Sensor Systems – The whole range of pHSense pH meters can be fitted with additional sensors such as chlorine or ORP. Please ask your local distributor for more details.

The sensor at the heart of the Process Instruments online pH meter is a patented gel filled glass electrode. This pH electrode is far superior to many online process pH electrodes on the market and is designed for a long life, low drift and high reliability.

Unlike many pH analyzers, you don’t need to search through hundreds of pH electrodes to find one that works in your process as the pHSense electrode works in all environments from pH 2 to 12 and in conductivity from 0µS upward. Although they command a higher price in the market place these sensors are more than cost effective with their longer life and considerably lower maintenance requirements, typically only needing calibration once per two or three months. Despite the superior functionality that the pHSense has to offer, the purchase costs are less than or comparable to, its competitors!

The pHSense online pH meter takes away the requirement for continual calibration and re-calibration of the pH meter by operators as it utilises an extremely stable pH electrode. The pHSense will calculate a ‘degree of confidence’ in its own calibration and let you know if its confidence is low. If the pH meter detects a fault in the pH sensor then it gives instructions on the display as to what the fault may be, with full on board fault diagnostics.
