UNI-T UT501A Digital Insulation Resistance Tester – 1000V, 5.5GΩ

The UNI-T UT501A is a highly reliable, entry-level digital insulation resistance tester. Offering test voltages of 100V, 250V, 500V, and 1000V, it accurately measures insulation resistance up to 5.5GΩ. Designed for straightforward operation, it features a 2000-count backlit LCD, auto-discharge safety functions, and AC voltage measurement up to 750V, making it a staple tool for general electrical maintenance.

Equip your electrical toolkit with the industry standard: the UNI-T UT501A Digital Insulation Resistance Tester. For independent electricians and building maintenance teams in Pakistan, complex diagnostics aren't always necessary—you just need a fast, accurate tool to ensure cables and small motors are safely insulated. The UT501A is designed for maximum simplicity and rugged reliability.

Delivering standard test voltages up to 1000V, it measures resistance up to 5.5GΩ, easily identifying degraded building wiring, water-damaged motor windings, or failing electrical switches. It features an integrated AC Voltage Tester (up to 750V), allowing you to confirm that a circuit is dead before applying the high-voltage test. The automatic discharge function ensures that dangerous trapped voltage is safely bled off the circuit immediately after the test button is released.
