TDS-3 Handheld TDS meter


Ideal for commercial use, the TDS-3 includes a carrying case with belt clip. It is highly efficent and accurate due to its advanced microprocessor technology. It features a measurment range of 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1 ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking image.

Why are PPM, TDS, pH and EC important?

PPM and TDS are abbreviations that represent the concentration of elements in a solution or atmosphere. PPM is short for Parts Per Million and TDS for Total Dissolved Solids. EC (electroconductivity) is another form of measurement for TDS. pH is the measure of acidity or alkalinity which dictates plant uptake of particular elements.

What is the suggested pH range for my hydroponic system and soil plants?

Hydroponic and soil gardens differ in the fact they both need different pH ranges for nutrients to be made available for plant absorption. Maintain a pH between 5.0 and 6.5 for hydroponic gardens and 6.0 to 7.0 for soil applications.
