Online pH and ORP Meter CRIUS® 100
Online pH meters and pH controllers are one of the most common analysers in use today in water treatment and process plants and yet online pH meters cause continual problems for their operators. What is needed is a stable, reliable, online pH meter for a reasonable cost. That is exactly what you get with the CRIUS® 100 and CRIUS® 100 automatic calibrator.

The sensor at the heart of the Process Instruments online pH/ORP meter is a patented polymer filled glass electrode. This pH or ORP 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 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 upward.
Good pH meters are few and far between and they often have limitations or command extraordinarily high prices. The CRIUS® 100 pH monitor takes away the requirement for continual calibration and re-calibration of the pH/ORP meter by operators as it utilises an extremely stable pH electrode. The CRIUS® 100 pH analyser 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 or 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 pH meter is capable of full PID control and is equipped with process control options, datalogging, relay outputs, serial comms, (TCP, Ethernet, ModBus are available now with Profibus available soon). Remote Access of the pH and ORP meters (including remote access to all control options) is available via the internet, and via a LAN. In fact the CRIUS® 100 has all the options you could want in a pH meter and ORP meter whilst maintaining a low cost and great value for money.
