Digital ohmmeter IPR-2

bench-top

Product overview

• Fast and accurate measurement of synthetic resistance for underground lines
• Co-developed with Tokyo Electric Power Grid Co., Ltd.

Overview
Instrument designed to measure synthetic (artificial) resistance for management of grounding where maintaining single-point grounding resistance is difficult. Applying synthetic resistance management can reduce the need for grounding renovation works.

Improvements over IPR-1

• Expanded measurement range to increase applicable cases
• Measurement time reduced by approximately half
• Improved LCD display legibility
