LC-pH-3S Keypad Benchtop pH Meter, -2.00-18.00 pH and ±0.01 pH Accuracy (CAT#: STEM-BC-3995-ZJF)

The LC-pH-3S is a keypad benchtop meter for accurate pH, ORP, and temperature measurement. It is designed for research, quality-control, biotechnology, fine-chemical, and titration laboratories. The 6.5-inch LCD presents measurement values and operating information clearly. Long-life tactile buttons provide direct access to calibration and system functions. A built-in microprocessor supports automatic calibration, manual or automatic temperature compensation, and result storage. New pH and temperature electrodes enable automatic temperature correction and manual salinity compensation. Digital filtering and sliding-difference algorithms improve response speed and measurement accuracy. The instrument recognizes fifteen buffer solutions and supports one-, two-, or three-point calibration. It stores 300 measurement sets and supports USB export, Bluetooth printing, and optional mobile application connection.
