The HANNA pHep pH Tester (HI98107) 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 of0.1 pH. The pH range of the HANNA pHep 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 ? or ?. The LCD screen has stability and calibration tag indicators. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available. The pH electrode of the HANNA pHep uses a unique reference cell design that utilizes a cloth junction that provides a larger surface area than a standard ceramic junction. 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
