Fonctionnement
A glass pH electrode (BNC/Q9 input) is immersed in the sample solution; the electrode generates a potential proportional to H+ activity. The instrument amplifies this mV signal, applies temperature compensation from a 4-pin aviation connector temperature probe (ATC) or manual setting (VTC), and converts to pH using the slope and offset derived from the most recent buffer calibration. Auto-hold senses signal stability and locks the reading; results stream to the on-board GLP-compliant 500-record memory and out via USB or RS-232.
