Two important measurements in one instrument. The PCTestr tests conductivity and pH while the PTTestr tests TDS and pH. They feature easy-to-read displays, push-button calibration, HOLD function, and error messages. Valox® housing and stainless steel electrodes offer good chemical compatibility and durability, and are designed to float,. All waterproof Testrs have replaceable sensors.
Frequently Asked Questions
Q: Why are PPM, TDS, pH and EC important?
A: 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 (electro conductivity) is another form of measurement for TDS. PH is a measure of acidity or alkalinity which dictates plant uptake of particular elements
