Every CRIUS®4.0 controller comes with the capability of connecting remotely to any internet enabled device. It does this using the MQTT Internet of Things communications protocol, the first analyzer in the world to do so. This gives full, live remote access to the analyzer, the data and the setup.
Additionally in Jan 2021, Pi launched a cloud based Data Acquisition Reporting and Storage application called Data Insite® capable of live streaming data from CRIUS®4.0 and any other internet capable device.
Pi is known to make the best water quality analyzers on the market – so it’s not surprising that other companies want to sell them as their own under Private Label agreements. As well as the original design and manufacture, Pi provides all the training that their customers need. Our Private Label customers save a fortune on Research & Development by selling our products under their own branding, and so could you. We even do custom programming to enable the analyzers to perform specialist control based on our private label customers’ requirements. From controlling ozone generators to managing monochloramine generators to controlling a chlorine dioxide generator, Pi has done it all before so ask us about your specialist requirements.
The many innovations brought to market by Pi, such as the patented turbidity meter “TurbSense®” and the patented suspended solids monitor “SoliSense®” are the result of years of working together with prestigious educational institutions such as The University of Manchester, The University of Lancaster and The University of Warwick. This continual product development has led to Pi being awarded numerous honors over the years, including the International Achievement and Editor’s Choice Award at the Red Rose Awards, the Technology Award at the Lancashire Telegraph Business Awards, and the Innovation Award at the Burnley Business Awards. In 2021, Pi was awarded two Queen’s Awards for Enterprise; for Innovation (for the CRIUS®) and for International Trade.
More importantly, it has meant that Pi can add value to our customers’ processes and products by developing products that really satisfy a need. Recent examples include CRIUS®4.0, the world’s first MQTT enabled instrument controller, and CoagSense, a fully automatic coagulation controller for any size of municipal water treatment plant.
With the exception of 2020, Pi has attained growth of more than 20% year-on-year since the launch of its products and continues to heavily invest in Research & Development. So you can always rely on us to deliver the most technologically advanced water analyzer and controller systems on the market.
What the future holds for Pi...
Ever-expanding, ever-adapting, ever-enhancing. With numerous ongoing product developments constantly underway, it’s a safe bet that Pi will always be at the top of the water quality analyzing industry.
