Digital Ohmmeter 20K?

Product Code : SCL-EAE-12251

The Digital Ohmmeter 20KΩ is a laboratory resistance-measuring instrument used for checking resistance values up to 20KΩ in school and college physics or electronics circuits. It is suitable for physics labs, electronics classrooms, STEM labs, technical institutes, distributors, and educational procurement buyers.

Product Description

The Digital Ohmmeter 20KΩ from Science Lab Supplies is intended for practical electrical measurement where students and teachers need to measure resistance in ohms or kilo-ohms. The supplied product name confirms a 20KΩ measuring range; exact display type, resolution, accuracy, test-current method, lead type, power source, case material, and certification must be confirmed before publication.

This ohmmeter supports classroom work on resistance, continuity checking, resistor identification, circuit testing, and Ohm’s law demonstrations. It should be used only on de-energized circuits or isolated components, according to the final supplied model instructions.

Key Features

• 20KΩ resistance range: identified from the supplied product name; final operating details must be verified.
• Digital resistance reading: supports easier observation and recording during laboratory practicals where display details are confirmed.
• Physics and electronics use: suitable for resistance measurement, circuit checking, and component testing in supervised labs.
• Ohm’s law support: helps students connect resistance values with voltage, current, and circuit behaviour.
• Reusable measurement instrument: suitable for repeated school, college, STEM, and vocational electronics sessions.
• Safety-led use: designed for resistance checks on non-live circuits and isolated components.
• Honest specification handling: no accuracy, calibration, protection, or certification claim is made without documentation.

How to Use the Digital Ohmmeter 20KΩ

1. Confirm the resistance range, power source, lead type, and operating instructions before use.
2. Switch off the circuit and disconnect external power before measuring resistance.
3. Discharge capacitors and isolate the component if the experiment requires it.
4. Connect the test leads or terminals as specified for the supplied model.
5. Select the correct range if the ohmmeter has range selection.
6. Touch the probes across the resistor, wire, coil, or circuit section being tested.
7. Read the value on the digital display and record it with the correct unit, such as Ω or kΩ.
8. Remove the probes and switch off the instrument after use.

Safety note: Use only under trained supervision. Do not measure resistance on a live circuit, do not exceed the verified range, do not use damaged leads, and do not open the instrument while connected to any circuit.

Care & Maintenance

• Store the ohmmeter in a dry, dust-free laboratory cabinet after use.
• Inspect the display, leads, probes, terminals, and case before each practical session.
• Clean the outer body with a soft, dry cloth; avoid liquid cleaners unless approved.
• Arrange qualified service support for display faults, loose terminals, battery leakage, or calibration issues.
