Waterproof Handheld pH Meter - These handheld pH meters make testing easier and more reliable. All information is displayed on an LCD that gives you the complete picture at a glance. At startup, they perform a self-check and then display the remaining battery level to assure proper working condition. The stability indicator tells you when to take the reading and the hold button freezes the display for easy and accurate recording. In addition, the Battery Error Prevention System (BEPS) avoids erroneous reading caused by low-voltage level by automatically turning off the meter.
