PH-100pro+ Rechargeable Pen-Type pH Meter, -2.00-16.00 pH (CAT#: STEM-BC-3987-ZJF)

The PH-100pro+ is a rechargeable pen-type pH meter for water-quality testing in field and laboratory environments. It is applicable to municipal water monitoring, aquaculture, environmental protection, industrial processing, beverages, and research work. The VA black-film display presents white characters on a black background for high visual contrast. Its backlight remains continuously illuminated during operation. The meter measures pH and temperature simultaneously and provides automatic temperature compensation. Users can select single-point or multi-point calibration and choose Chinese, US, or European buffer standards. A manual reading-lock function allows stable values to be retained for recording. The automatic shutdown period can be configured according to user preference. Electrode-condition monitoring provides an indication of electrode wear and supports timely replacement planning.
