PH-100 Pen-Type pH Meter, 0.01-14.00 pH (CAT#: STEM-BC-3983-ZJF)

The PH-100 is a compact pen-type acidity meter for precise water-quality measurement in laboratories and field environments. It can be used for tap-water monitoring, aquaculture, environmental protection, printing and dyeing, electroplating, beverages, and research applications. The LCD simultaneously displays pH and temperature values. Its 0.01 pH resolution supports more detailed measurement than basic portable testers. Automatic temperature compensation corrects readings within the specified temperature range. The data-hold function preserves a stable result for convenient observation and recording. Users can switch the temperature display between Celsius and Fahrenheit. A replaceable three-in-one composite electrode incorporates a blue-sensitive bulb and ceramic temperature element. The waterproof enclosure and internal flotation structure help protect the instrument during accidental immersion.
