LC-pH-3LT Touchscreen Benchtop pH Meter for Strong Acids and Bases, ±0.01 pH (CAT#: STEM-BC-3991-ZJF)

The LC-pH-3LT is a touchscreen benchtop pH meter configured for strong acidic and alkaline sample measurement. It is intended for research, quality-control, chemical-processing, biotechnology, and titration laboratories. The instrument provides pH, ORP, and temperature measurement through a digital microprocessor platform. Its color TFT touchscreen offers clear parameter display and responsive operation. Automatic calibration and selectable automatic or manual temperature compensation simplify method setup. A compatible acidity electrode and temperature probe support measurement under demanding chemical conditions. Digital filtering and sliding-difference algorithms improve signal response and result accuracy. The system recognizes fifteen standard buffers and supports one-, two-, or three-point calibration under three selectable buffer standards. Measurement records can be stored internally, exported by USB, printed wirelessly, or transferred through compatible Bluetooth functions.
