Total Dissolved Solids Monitor RO-CHECK™ POU TDS Monitor from Myron L Company

RO-CHECK,POU,TDS,Monitor,Myron L CompanyTotal Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water, expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm). Total Dissolved Solids (TDS) is directly related to the purity of water and the quality of water purification systems and affects everything that consumes, lives in, or uses water, whether organic or inorganic, whether for better or for worse.

The innovative Myron L RO-CHECK (U.S. Patent # 4,762,611) reliably monitors total dissolved solids 24 hours a day. A quick glance at the display assures RO users of their water TDS quality. Should membrane failure or other problems cause TDS to rise above the set point, the words "CHECK SYSTEM" flash in the LCD. This silent indicator alerts, rather than alarms, the user that service may be required.

Easily installed on most popular faucets, the RO-CHECK features 16 set point choices and is ideal for monitoring water of almost any TDS quality.

Two display modes:


TDS is below set point
