StemAids Conductivity Tester is an educational science laboratory instrument designed to test whether a material or solution can conduct electricity. It is suitable for school chemistry laboratories, physics classrooms, general science practicals, STEM labs, and teacher-led demonstrations on electrical conductivity, circuits, electrolytes, conductors, and insulators.
The conductivity tester helps students compare the conducting ability of different samples such as metals, graphite, salt solution, tap water, distilled water, sugar solution, and other approved classroom materials. It provides a simple visual indication through a bulb, LED, meter, buzzer, or indicator system depending on the supplied model.
Product Highlights
- Educational conductivity tester for science and STEM practicals
- Useful for testing conductors, insulators, electrolytes, and non-electrolytes
- Suitable for chemistry, physics, electrochemistry, and general science lessons
- Helps students compare conductivity of solids and liquids
- Supports classroom demonstrations of circuits, ions, and current flow
- Recommended for teacher-supervised educational laboratory use
Product Description
The StemAids Conductivity Tester is designed to demonstrate the basic principle of electrical conduction. When the tester probes are placed in contact with a conducting material or dipped into a conducting solution, the circuit is completed and the indicator responds. If the sample does not conduct electricity, the indicator remains off or shows little response.
This tester is useful for explaining why metals conduct electricity, why ionic solutions such as salt water conduct current, and why substances such as sugar solution or distilled water may show weak or no conductivity. It helps students understand the difference between conductors, insulators, electrolytes, and non-electrolytes through direct observation.
StemAids provides educational laboratory instruments that support hands-on science learning, safe classroom demonstrations, and concept-based teaching. The StemAids Conductivity Tester is suitable for school science labs, college practical rooms, STEM activity centers, and institutional laboratory procurement.

Frequently Asked Questions
1. What is the StemAids Conductivity Tester used for?
The StemAids Conductivity Tester is used to check whether a material or solution conducts electricity during chemistry, physics, general science, and STEM practicals.
2. Is this conductivity tester suitable for school laboratories?
Yes, it is suitable for school science labs, college chemistry labs, physics classrooms, STEM labs, and teacher-supervised practical demonstrations.
3. What samples can be tested with this instrument?
Approved classroom samples such as metals, graphite, salt solution, tap water, distilled water, sugar solution, and selected acid or alkali solutions can be tested under supervision.
4. How does a conductivity tester show that a sample conducts electricity?
The tester completes a circuit through the sample. If the sample conducts electricity, the indicator such as a bulb, LED, buzzer, or meter responds according to the supplied model.
5. Why does salt solution conduct electricity?
Salt solution conducts electricity because it contains mobile ions that allow current to pass through the liquid between the tester probes.
6. Does sugar solution conduct electricity?
Sugar solution usually shows little or no conductivity because sugar dissolves as neutral molecules and does not produce mobile ions in water.
7. Can students use the Conductivity Tester independently?
Students should use the tester under teacher or laboratory supervisor guidance, especially when testing liquid samples, acid/alkali solutions, or electrical circuits.
8. Can this tester be used on wall sockets or live electrical wiring?
No, this tester is intended only for educational low-voltage conductivity demonstrations. It must not be used on mains electricity, wall sockets, live wiring, or high-voltage circuits.
9. How should the tester be cleaned after use?
After use, wipe the probes clean, rinse and dry them if used with solutions, switch off the tester if applicable, and store it in a clean, dry place.
10. Is this product suitable for certified electrical testing?
No, StemAids Conductivity Tester is intended for educational laboratory and classroom learning. For certified electrical or analytical testing, use calibrated professional instruments and approved standards.
