LC-pH-2B Keypad Benchtop pH Meter, -2.00-18.00 pH (CAT#: STEM-BC-3994-ZJF)

The LC-pH-2B is a keypad-operated benchtop meter for measuring pH, ORP, and temperature in aqueous solutions. It is suitable for scientific research, quality control, biotechnology, fine chemicals, and acid-base titration. A 6.5-inch LCD and long-life tactile keys provide clear display and reliable operation. The internal microprocessor supports automatic calibration, automatic or manual temperature compensation, data storage, and configurable settings. Digital filtering and sliding-difference processing improve response speed and reading stability. The instrument automatically recognizes fifteen buffer solutions from European and US, NIST, and Chinese standards. One-point or two-point calibration can be selected according to the measurement procedure. Up to 300 results can be stored and exported by USB for spreadsheet review. Standard Bluetooth connectivity supports a wireless printer, while an optional mobile application and IP54 enclosure improve operating flexibility.
