PH-100A Backlit Pen-Type pH Meter, 0.01-14.00 pH (CAT#: STEM-BC-3984-ZJF)

The PH-100A is a portable pen-type pH meter with a backlit LCD for use in bright or low-light environments. It is intended for water-source monitoring, aquaculture, environmental analysis, industrial water testing, beverages, and scientific research. The display presents pH and temperature readings simultaneously. A backlight improves visibility during fieldwork and poorly illuminated laboratory procedures. The instrument provides automatic temperature compensation from 0 to 50°C. A data-hold function keeps the measured value on screen for convenient documentation. Celsius and Fahrenheit units can be selected according to user preference. The replaceable three-in-one electrode head includes a sensitive glass bulb and ceramic temperature sensor. Its waterproof body, built-in flotation design, and durable waterproof buttons support reliable portable operation.
