Insulation testers are used to measure the electrical resistance of insulation in electrical equipment and systems. These testers play a crucial role in ensuring the safety and reliability of electrical systems by checking the integrity of the insulation, identifying weak spots or faults, and determining if the insulation is adequate to protect against electrical shock, fire, and other hazards.

REED Instruments electrical insulation testers are widely used in the electrical maintenance and repair, manufacturing, and quality control industries and are backed by a 1-year manufacturer's warranty.
