About This Item Hanna Waterproof Pocket pH Tester: The HI98107 pHep® is an easy-to-use pH water tester that makes monitoring water quality simple. This accurate pH tester features 0.1 resolution with automatic two-point calibration and temperature compensation in a single, portable, pocket device. The 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 of ±0.1 pH. The pH range of the HI98107 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 startup alerting the user to the remaining battery power that is available. The pH electrode 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 value is recognized and stability is reached, the meter automatically accepts and stores the calibration value. Setup options include automatic shut off timing and temperature unit displayed. Automatic shut-off options are to turn the water pH meter off after 8 minutes, 60 minutes, or disabled. To enter the setup mode the user presses a button located in the battery compartment. Downloadable Manual
