Benchtop pH/mV/°C Meter LMPH12 is a high-precision laboratory instrument designed for accurate pH, mV, ORP, and temperature measurement across research, pharmaceutical, environmental, and industrial testing applications. The instrument combines advanced calibration capability with intelligent diagnostic functions to deliver reliable analytical performance.
The system features a large backlit LCD display with user guidance prompts for simplified operation and efficient sample analysis. Automatic temperature compensation ensures accurate measurement across the entire operating range, while automatic electrode diagnostics display electrode slope after calibration for improved monitoring of electrode condition.
The meter supports up to five-point push-button calibration with automatic buffer recognition and selectable buffer standards. It also includes calibration due reminders, helping laboratories maintain measurement accuracy through scheduled recalibration routines.
The instrument supports both absolute and relative millivolt measurement for precise ORP analysis. Automatic endpoint detection freezes stable measured values for consistent recording and improved repeatability during testing.
An expanded internal memory allows storage of up to 500 readings with date and time stamping to support GLP-compliant laboratory documentation. The setup menu enables users to customize calibration points, buffer standards, resolution, temperature units, stability conditions, and operational settings according to laboratory requirements.
LMPH12 is suitable for laboratories requiring advanced pH analysis with high accuracy, flexible calibration, and comprehensive data management capability.
