The Bluelab Combo Meter is a conductivity, pH and temperature meter all in one. It comes with a pH probe and conductivity and temperature probe, which are simply placed into the solution and the selected reading is displayed on screen. The Bluelab Combo Meter is portable and does not require a power supply. Calibration of the pH is very easy, using the push buttons on the meter and fresh Bluelab calibration solutions. Conductivity and temperature do not need to be calibrated as this is locked in during manufacture. Select display options for C or F and EC, CF or ppm.
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.
