The pHep is used by millions of people around the world to control pH in laboratories and industrial applications, as well as in agriculture, aquaculture, food production and quality control, swimming pools and the printing industry.

With a renewable cloth junction, the pHep has a longer lifespan than typical pH testers. An ordinary junction will become clogged with use and a tester should normally be discarded once the junction becomes contaminated. The junction is 2 cm long and can be pulled out when contaminated to expose a new section to effectively extend the life of the tester.

Automatic calibration

If calibration is required, simply submerge the electrode tip in the calibration solution and the meter will calibrate automatically!

Exposed temperature sensor

These testers feature exposed temperature sensors for faster response times.

Water resistant

An easily removable cover provides access to the battery compartment.
