Digital Ohms Meter – 20K
Product Code : SCL-PLE-11692
The JLab India Digital Ohms Meter (20KΩ) is a dedicated, high-stability laboratory instrument engineered for the empirical study of electrical resistance and circuit components. Optimized for Secondary and Technical Vocational (TVET) curricula, this meter provides a focused 0–20,000 Ω measurement range, eliminating the complexity of multi-function multimeters for foundational physics experiments. It facilitates the quantification of Ohm’s Law and the verification of series/parallel resistor networks within institutional laboratory environments.
