ORPSense

The ORPSense range of ORP Meters from Pi utilise the very latest and best ORP sensors available in the world today for measuring the online Redox potential of any aqueous solution. They are platinum ball based sensors with integral reference electrodes which use no reagents, are extremely stable, and have reduced maintenance and reduced whole life costs.

ORP Sensor ORP Sensor

Online ORP meters and ORP controllers are one of the most common analysers in use today in water treatment and process plants and yet online ORP meters cause continual problems for their operators. What is needed is a stable, reliable, online ORP meter for a reasonable cost. That is exactly what you get with the ORPSense and the ORPSense Automatic Calibrator.

The ORPSense sensors and flow cells are available with different controllers giving you the same great performance with different communication, display, and control options. With the ORPSense range of ORP meters, you get everything that you need – and nothing that you don’t.

The sensor at the heart of the Process Instruments online pH/ORP meter is a patented polymer filled glass electrode. This ORP electrode is far superior to many online process ORP electrodes on the market and is designed for a long life, low drift and high reliability. Unlike many ORP analysers, you don’t need to search through hundreds of ORP electrodes to find one that works in your process as the ORPSense 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 all of the additional functionality that this unit has to offer, the purchase costs are less than or comparable to, its competitors!

The ORPSense ORP monitor takes away the requirement for continual calibration and re-calibration of the ORP meter by operators as it utilises an extremely stable pH electrode. The ORPSense 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 ORP sensor then it gives instructions on the display as to what the fault may be, with full on board fault diagnostics.

The online ORP meter is capable of full PID control and is equipped with process control options, data-logging, relay outputs, serial communications, (TCP, Ethernet, Modbus are available now with Profibus available soon). Remote Access of the ORP meter (including remote access to all control options) is available via the internet, and via a LAN. In fact the ORPSense has all the options you could want in an ORP meter whilst maintaining a low cost and great value for money.
