Features
Equipped with an LCD display that presents all data on a single screen. Features a user-friendly interface with button-operated settings, ensuring clear visibility and intuitive operation.
Complies with IP65 protection rating through sealed enclosure design, effectively preventing liquid ingress that could corrode internal circuits and ensuring operational safety.
Supports data storage, deletion, and review functions for comprehensive record management.
Incorporates parameter memory function to automatically recall previous settings upon repowering, streamlining operational procedures. Features power-off protection and factory reset functionality.
Enables automatic recognition of three pH calibration buffers (GB4.00, 6.86, 9.18). Supports electrode calibration with up to 3-point calibration (PH30-3/4 Models).
Offers dual measurement modes: Continuous Measurement and Stable Measurement (PH30-3/4 Models).
Provides both manual and automatic temperature compensation options (PH30-3/4 Models).
Supports data printing and PC connectivity for data export (PH30-3/4 Models).
