Digital Water Quality Tester - TDS Meter

Part Number: TDS-METER
Availability: Out of Stock.
Quick, Easy Test for TDS (Total Dissolved Solids) Impurity Level
Fast & Easy Testing

Accurately measure your pool or spa's water quality / hardness instantly. This tester measures the total amount of impurities dissolved in the pool water from 0 - 9999 parts per million (PPM) and displays it on an easy-to-read digital LCD screen.

Knowing how much your TDS level differs from your salinity level will show you the level of unwanted impurities are present in the pool water. Knowing your TDS also allows you to calculate your Langelier Saturation Index (LSI) , which is the part of your swimming pool water chemistry which prevents pool water from being excessively scale forming (high LSI) or aggressively corrosive (negative LSI). That way you can keep you pool water as pure, clean, and safe as possible!

super easy
Very useful, gives a reading in just a second. I use it to check after I get a lot of kids swimming and after storms to help me get ahead of pool problems.
