Monitors, Meters, & Controllers

Reverse Osmosis Systems can be upgraded in many ways and a couple of those upgrades are almost essential. TDS (Total Dissolved Solids) and Pressure gauges are found on a lot of RO Systems because they simply let you know how your RO/DI System is performing but also helps you troubleshoot any possible problems you may encounter. Ultimately we want the cleanest water we can get and a TDS meter will let you know in a whole number how many dissolved solids are in your water and if the number is higher than zero, it is a good sign that your DI Resin should be changed or a possible problem with your Reverse Osmosis Membrane.
