HM Digital QC-1 Quick Check TDS Monitor, 1/4" Push-In

The HM Digital QC-1 is a simple push-button TDS and conductivity monitor that uses a green/red LED to indicate whether water quality is within an acceptable range or the system needs service. Eight programmable set points are selected via internal dip switches, and the unit ships factory calibrated to 100 ppm NaCl. The 1/4" push-in connection installs directly into 1/4" tubing.

Installed on residential and commercial reverse osmosis and deionization systems where a clear pass/fail indication is more useful than a numerical readout. Used in RO storage tank outlets, drinking water dispensers, and DI polishing loops to alert users when membrane or resin replacement is due.
