Microprocessor Potentiometer

Microprocessor Potentiometers Model 120, 121, 122 are solid state instruments designed to provide the precise potentiometric measurements. The instrument uses the latest microcontroller technology and advanced engineering techniques so as to give enhanced accuracy and reproducibility. The system has 3 soft touch keys for ease of operation. The calibration is retained even after the instrument is switched OFF. Provision for internal standard is provided. Provision is also available for attachment of two burette systems(in model 122) and single burette system(in model 121). The system has built-in magnetic stirrer which operates at fixed RPM. It is extremely useful for titration in pharmaceutical and chemistry labs.
