Say goodbye to uncertainty – this meter provides clear and concise data to help you maintain optimal water quality.

Designed for convenience, this meter features an auto-off function that conserves battery power by shutting off automatically after 3 minutes of inactivity. Plus, with diagnostic error messaging and shielded sensor cables, troubleshooting and maintenance are a breeze.

Powered by two AA batteries, this TDS meter boasts long-lasting performance to keep you informed around the clock. 

What sets the DM-3 apart from the DM-2 is its all-new slim design and extra large backlit screen, allowing you to effortlessly read measurements in low-light conditions.

Installation

This DM-3 meter can be configured in a variety of different ways depending on your needs. Typically, the IN line is connected to the source water and the OUT line is connected to the product water.

1. Start by inserting the two sensors fully into the bottom of two T-fittings (sold separately).
2. Orient the sensor pins so that they are perpendicular to the direction of the T-fitting. The water should flow over both pins equally.
3. Disconnect the water source.
4. Snip the source water tube at a point between the source and the filter. Insert both ends of the tube into the top of the IN line sensor's T-fitting.
5. Snip the product water tube at a point between the filter and a dispenser. Insert both ends of the tube into the top of the OUT line sensor's T-fitting
6. The DM-3 meter can be attached anywhere on or near your pure water system using the included mounting bracket, which can be secured by screws or adhesive tape.
7. Reconnect the water source.

Now you are ready to start using your TDS meter!

*This TDS Meter is not fully waterproof. Only the testing tip should be submerged.
