pHin chemicals are compatible with the Sutro monitor. They can be selected by scanning the bar code of the chemicals while setting up your chemical profile in the application. If for any reason the chemicals cannot be scanned in, the equivalent chemical from the default chemicals can be selected.
Both methods will give the same recommendations, however, the name of the chemical will be the one that was selected.
The recommendations for pHin chemicals are not fully converted due to pHin's pre-measured pod design. Full support for pre-measured chemicals may come at a later date if additional companies continue exploring this method of treating water.
In the near term, please use the following tables to convert from the Sutro recommendation to the number of pods required. If the number is not even, it is safer to round down to the nearest whole pod so as to not over treat. The Sutro monitor will test again within 8 hrs to make any corrections.
