LC-pH-3WT Touchscreen Benchtop Pure-Water pH Meter, -2.00-19.99 pH (CAT#: STEM-BC-3992-ZJF)

The LC-pH-3WT is a touchscreen benchtop meter configured for pH measurement of pure-water samples. It is suitable for research, water-quality control, biotechnology, fine chemicals, and analytical laboratories. The system measures pH, ORP, and temperature using high-input-impedance electronics. A color TFT touchscreen provides clear access to measurement data and instrument settings. The microprocessor supports automatic calibration, temperature compensation, data storage, and configurable operating functions. A dedicated pure-water measurement configuration improves suitability for low-conductivity samples. Digital filtering and intelligent signal processing improve response stability and result accuracy. The instrument automatically recognizes fifteen buffer solutions and supports three selectable calibration standards. Up to 500 measurement records can be stored and transferred by USB, Bluetooth printer, or a compatible mobile application.
