LC-pH-4T Touchscreen Benchtop pH Meter, 0.001 pH Resolution (CAT#: STEM-BC-3993-ZJF)

The LC-pH-4T is a high-resolution touchscreen benchtop meter for precise pH analysis of aqueous solutions. It is designed for scientific research, biotechnology, quality control, fine chemicals, and acid-base titration. The instrument measures pH, ORP, and temperature with enhanced pH and millivolt resolution. Its color TFT touchscreen provides an intuitive interface for measurement, calibration, and data review. The internal microprocessor supports automatic calibration and automatic or manual temperature compensation. Digital filtering and sliding-difference technology improve response speed and measurement precision. Fifteen buffer solutions are recognized automatically, with European and US, NIST, and Chinese calibration series available. The instrument stores 500 result sets and supports USB export, Bluetooth printing, and optional mobile-device connection. Intelligent electrode-status evaluation and IP54 construction improve measurement reliability and protection during laboratory use.
