The device is designed to measure the total amount of all substances dissolved in water. The reading range is 0-9999, for results greater than 999 ppm, the symbol [x10] appears on the display. The measuring device is installed on RO filters, allowing for constant observation of water contamination values in the range of 0-9990 ppm.

Characteristics:
- The meter is equipped with a switch for reading the current TDS value (in/out).
- The package includes cables, probes, and tees that allow connection to standard 1/4 inch pipes (typical for home water filters).
- To save battery, the device automatically turns off after 10 minutes of inactivity.
- Sensors are placed in tees with John Guest quick connectors, allowing hoses to be connected quickly without the need for any additional sealing.
- The Dual TDS Meter is mounted on two self-adhesive Velcro strips, making both installation and removal very quick and hassle-free.
- After disconnecting the TDS tees, it can be used as a regular portable meter, i.e., single TDS-Meter.
