Easy to understand Portal

You don’t need to be an expert to be able to use our portal as our unique AI will analyse risks 24/7. No need to go through thousands of lines of data or try to interpret hard to understand line graphs. With our clear traffic-light style risk displays and easy to understand charts you can be confident that you will be alerted quickly and be able to deal with any issues as they arise.

Checklist

Increase Compliance

It’s very simple - With manual water monitoring it is common to take only 12 readings per year per outlet and trying to understand how often an outlet is used is virtually impossible. Angel Guard’s digital water-monitoring system can capture over 157 million data points a year per outlet and analyses the data for you – only Alerting when a risk is discovered. Which do you think is more accurate
