How Your TDS Meter Works
How Your TDS Meter Works
Dissolved minerals are invisible until they dry into spots and streaks. Your TDS meter tells you exactly how much is in your water — in seconds, before you ever pick up a hose.
01
Dip the probe
Insert the tip into any tap, tank, or reservoir. No calibration, no setup.
02
Instant digital reading
Get a precise PPM reading in seconds, right on the LCD display.
03
Know your number
Decide if your water needs the Spotless DI treatment for a 0 TDS finish.
One Meter. Every Water Source.
Wherever water quality matters, check it before you commit. Same meter, same instant accuracy.
Luxury Car Care
Test rinse water before it ever touches paint.
Residential Windows
Confirm a streak-free finish before the squeegee comes out.
Solar Panels
Keep every cell clear of mineral haze that blocks the sun.
Glass Balustrades
Spot-check hard water before it marks the glass for good.
