In-Line TDS Monitors

HM Digital TDS Monitors can be installed on any water supply or water filtration system including reverse osmosis systems, coolers and more, to measure and display the TDS levels of the purified product water and/or incoming feed water.

HM Digital TDS Monitors are available in single and double monitor configurations:

• Dual TDS monitors display the TDS levels on two water lines.  These are most commonly used on the feed and product water lines of an RO system to monitor the performance of the system as well as the quality of the product water being used.
• Single TDS Monitors display the TDS level on a single Water Line. These are most commonly used on the product water line of an RO system to monitor the quality of the product water being used.  

Note:  Clean Tap Monitor CT-1 has been discontinued by the manufacturer and is no longer available.   Please choose from the new Filter Monitors below.
