Residual Ozone Analyser CRIUS®4800
Residual Ozone Analyzer from Pi for the measurement of ozone concentration in water, is designed to be simple to install and operate and offers unrivalled stability, accuracy and precision, while offering excellent value for money.

The CRIUS® 4800 Residual Ozone Monitor suffers no interference from other oxidants such as Chlorine. Coupled with its excellent zero and calibration stability it is extremely well suited to the monitoring of the Residual or Dissolved ozone concentration in water in clean or harsh environments.
The Residual O3 Monitor is bufferless and reagent free, meaning it has a low total cost of ownership and with maintenance intervals at 3 or even 6 months, the bufferless Ozone Monitor is fast becoming the instrument of choice for the engineer who wants the best chlorine monitor at the best price.
The CRIUS® 4800 Ozone Monitors are equipped with process control options, datalogging, relay outputs, serial comms, (TCP, Ethernet, ModBus are available now with Profibus available soon). Remote Access of the ozone monitors (including remote access to all control options) is available via the internet, and via a LAN. In fact the CRIUS®4800 ozone analysers have all the options you could want in a Ozone Analyser whilst maintaining a low cost and great value for money.
The maintenance interval is typically only twice per year thereby keeping operating costs to a minimum.
Anywhere you have a requirement to measure Ozone in water is a suitable application for this ozone monitor. The CRIUS®4800 Residual Ozone Analyzer is particularly suited to working in sites where reliability is paramount.
