LC-pH-3T Touchscreen Benchtop pH Meter, -2.00-19.99 pH (CAT#: STEM-BC-3990-ZJF)

The LC-pH-3T is a touchscreen benchtop meter for high-precision analysis of aqueous solutions. It is suitable for scientific research, quality control, biotechnology, fine-chemical processing, and acid-base titration. The instrument measures pH, oxidation-reduction potential, and temperature. A color TFT touchscreen provides direct access to calibration, measurement, storage, and system settings. The built-in microprocessor supports automatic calibration and automatic or manual temperature compensation. Digital filtering and sliding-difference processing improve response speed and measurement stability. The meter recognizes fifteen buffer solutions and supports one-, two-, or three-point calibration using European and US, NIST, or Chinese buffer series. Internal memory stores up to 500 result sets, which can be exported by USB and opened in spreadsheet software. Electrode-condition evaluation, Bluetooth connectivity, and an IP54 dust- and splash-resistant design support reliable routine operation.
