What’s new with
C+ Cassettes

3 white cassettes

Longer life

10% longer life from 29 days to 32 days, allowing for extra “measure now” readings.

Improved Measurements

More consistent measurements within and between cassettes.

Better Accuracy

More accurate measurements on every measurement.

New Alerts

Alerts and advice are now provided for CYA, Total Alkalinity, and Hardness.

Custom Temperature Alerts

Our App can now be configured so you can set alerts for low and high temperature. So you can get an alert when the water is warm enough to swim in or to know if the pool heater may have been left on.

What’s the same, and still the
only solution in the market that:

Measures 5 Chemistry Parameters

Provides automatic measurement of five critical chemistry parameters, pump flow, and temperature.

Measures Free Chlorine

Provides automatic measurement of Free Chlorine over 10 ppm. Most manual measurements also do not measure Free Chlorine above 10 ppm. Water over 10ppm is over-chlorinated and not healthy for people or equipment.

Measures True PPM

Measures actual chlorine levels in true ppm, not indirect millivolt readings like ORP systems. ORP systems estimate sanitizer strength instead of directly measuring free chlorine, and their readings can be affected by things like pH, temperature, stabilizer levels (CYA), swimmer waste, and other water conditions. They also often require frequent calibration and probe maintenance.
