Electroscope Polarity Detecting Manufacturer,Supplier and Exporter in India

Product Code : SCL-PLE-11866

The Electroscope Polarity Detecting by Scientifc Equipment is an educational physics laboratory apparatus designed to demonstrate static electricity, electric charge detection, charge polarity, electrostatic induction, charge transfer, and repulsion or attraction between charged bodies. It is suitable for school physics laboratories, college science labs, electrostatics practicals, STEM classrooms, teacher demonstrations, and supervised student experiments.

This polarity-detecting electroscope helps students observe whether an object carries positive or negative charge when compared with a known reference charge. It supports practical learning of charge separation, conductors, insulators, induced charge, grounding, electric fields, and basic electrostatic measurement concepts.

Product Description

An electroscope is a classic instrument used to detect the presence of electric charge. A polarity-detecting electroscope is used not only to show that charge is present, but also to help compare the type of charge using a known charged reference. When a charged object is brought near or touched to the terminal, the movement of the indicator leaf, foil, or pointer helps demonstrate charge behaviour.

The Scientifc Equipment Electroscope Polarity Detecting may include a metal terminal, conducting rod, indicator leaf or pointer, transparent protective case, polarity reference scale, grounding terminal, insulated support, base, and demonstration accessories depending on product configuration. It is designed for supervised educational and laboratory demonstration use only.

How to Use

1. Place the Electroscope Polarity Detecting apparatus on a stable, clean, dry, and level laboratory bench.
2. Inspect the terminal, enclosure, indicator leaf or pointer, grounding point, base, and accessories before use.
3. Ensure the electroscope is clean, dry, and free from dust or moisture for better sensitivity.
4. Charge a known reference object, such as an acrylic or ebonite rod, using the recommended rubbing material.
5. Bring the known charged object near the metal terminal and observe the indicator movement.
6. Charge the electroscope by contact or induction as directed by the teacher.
7. Bring the unknown charged object near the terminal without touching it and compare the response with the known charge.
8. Observe whether the indicator movement increases, decreases, or changes to help identify the relative polarity.
9. Discharge the electroscope by grounding it safely before repeating the experiment.
10. Repeat with different materials and record charge source, indicator movement, and polarity comparison results.
11. After use, discharge the electroscope, clean gently if required, and store it safely.

Safety and Handling Instructions
