It is great being able to monitor 3 stages of filtration By mfief on 6/26/2014mfief would recommend this product to a friendBeing able to monitor the TDS after the carbon blocks, ro unit, and after the DI resin is great. No need for un necessary filter changes. You can check three phases of filtration in seconds and replace only the necessary filters. This will save money in the long run.
