POTENTIOMETER with built in Variable speed Magnetic Stirrer

Provides stable and accurate endpoint detection due to continuous stirring

POTENTIOMETER with built in Variable speed Magnetic Stirrer

1. Application

  • Used for potentiometric titrations (acid–base, redox, precipitation)

  • Measurement of EMF of electrochemical cells

  • Suitable for:

    • Undergraduate (UG) and Postgraduate (PG) labs

    • Research laboratories

    • Industrial and pharmaceutical analysis

  • Variable stirring ensures:

    • Uniform mixing

    • Accurate and stable endpoint detection

2. Compliance / Standards

  • Designed as per standard laboratory instrumentation norms

  • Built-in standard reference cell (1.018 V) for calibration traceability

  • Operates on 230 V AC ±10%, 50 Hz supply

  • Uses μP (microprocessor) technology for accuracy and stability

  • Certified technology (e.g., Quantum Zuerkst) depending on manufacturer

3. Product Description

  • Microprocessor-based digital potentiometer

  • Integrated features:

    • Variable speed magnetic stirrer (50–500 RPM)

    • Inbuilt standard cell (1.018 V)

    • 10 μA constant current source

  • User-friendly:

    • Feather-touch controls

    • Digital LED display

  • Advantages:

    • High input impedance (no current drawn from test cell)

    • Smooth titration due to adjustable stirring

    • High precision measurements with minimal manual error
