The pHep® tester is for users that require the greatest accuracy and features while staying economical. Contains user-selectable automatic shut-off, replaceable pH electrode cartridge, stability indicator and automatic calibration.

It features a large multi-level LCD which displays both pH and temperature readings simultaneously. The pH readings are displayed with a 0.1 pH resolution and with an accuracy of +/- 0.1 pH. The pH range of the HANHI98107 is from 0.0 to 14.0 pH. An exposed temperature sensor allows for rapid automatic temperature compensated pH measurements. Temperature can be set to display in °C or °F. The LCD screen has stability and calibration tag indicators. The battery percent level is displayed at start up alerting the user to the remaining batt ery power that is available.

The pH electrode uses a unique reference cell design that utilizes an extractable cloth junction. A clogged junction will typically exhibit erratic readings that will not stabilize. Simply extracting a small portion of cloth from the water pH tester will clear any clog by exposing a fresh, clean surface. The ability to clear any clogging wille xtend the life of the pH electrode.

Calibration is performed by pressing the dedicated calibration button. Once in calibration mode, the pH electrode can be calibrated to 1 or 2 points using the pre-programmed standard buffers (pH 4.01, 7.01, 10.01). When the standard value is recognized and stability is reached, the meter automatically acceepts and stores the calibration value.

Set up options include automatic shut off timing and temperat ure unit displayed. Automatic shut-off opt ions are to turn the water pH meter off affter 8 minutes, 60 minutes, or disabled. To enter the setup mode the user presses a button located in the battery compartment.
