UNI-T UT511 Heavy-Duty Insulation Resistance Tester – 1000V, 10GΩ

The UNI-T UT511 is a robust, bench/field-style insulation resistance tester. Delivering test voltages up to 1000V, it accurately measures insulation up to 10GΩ. It features a massive 9999-count display with a 30-segment analog bar graph, automated PI/DAR calculations, and a built-in timer. Housed in a heavy-duty casing, it is the standard for testing large transformers and high-voltage motors.

Deploy industrial-grade durability with the UNI-T UT511 Heavy-Duty Insulation Resistance Tester. For heavy manufacturing facilities, textile mills, and WAPDA substations in Pakistan, handheld meters can sometimes be too fragile or difficult to read when resting on a transformer casing. The UT511 utilizes a rugged "lunchbox" style design, providing a highly stable base and a massive 9999-count display that can be read from a distance.

Outputting selectable test voltages of 100V, 250V, 500V, and 1000V, it measures insulation resistance up to 10GΩ. It is specifically engineered to measure the insulation of large transformers, generators, and industrial motors. The meter completely automates predictive maintenance by calculating the Polarization Index (PI) and Dielectric Absorption Ratio (DAR). The built-in 30-minute timer allows operators to initiate a test and walk away, perfectly suiting long-duration testing protocols.

Frequently Asked Questions (FAQs):

Q: What is the price of the UNI-T UT511 in Pakistan?

A: Visit Kamadi.pk for B2B pricing. We regularly supply the UT511 series to massive industrial factories and utility contractors.

Q: Does it have a PC connection?

A: No. The UT511 has an 18-group internal data logger but lacks a USB PC connection. If you need PC software reporting, you must upgrade to the UT512.

Q: What batteries power the UT511?

A: It is powered by 8 large 1.5V (LR14/C-size) alkaline batteries, providing extended runtime for heavy continuous testing.
