GENERAL FEATURES

LCD display screen, clear display.
It is suitable for laboratory potentiometric titration.
Support three titration modes: Auto Titration (Preset Endpoint Titration), Manual Titration and Control Titration.
Auto Titration allows to set the endpoint, range and delay time.
Manual titration allows to add continuously or add small amount.
Controlled titration allows to set the endpoint and switch titration speed with manual titraion.
pH calibration and measurement are supported.
pH supports automatic or manual calibration.
1-2 points calibration for pH with standard recognition.
Automatic/Manual temperature compensation ensures pH accurate results.
Automatic electrode diagnosis with pH slope.
An external 10mL or 25mL glass burette can be used for volume measurement (prepared by user).
