Hannna pHep

pHep(r), the standard in pH measurement with 0.1 pH accuracy, has 2 point calibration, large LCD, pull out replenishable junction and 700 hour battery life. The pHep(r) pH tester features a casing that is more rugged and has been ergonomically enhanced to better fit your hand. The pHep(r) comes with a protective cap that can be used as a measurement vessel. The electrode is replaceable by the operator. With the latest innovation of a non-clogging fiber junction the new pHep(r) meters last much longer. Calibrates on 7.0 and 4.0 solutions.

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.

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

A: 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.
