Product Introduction
MOEORW‑WRY73 is a high‑performance digital insulation diagnostic instrument engineered for power‑sector technicians, industrial maintenance groups, data‑center operators, oil‑site teams and quality‑control laboratories. This high‑voltage megohmmeter generates test voltage up to 5000 V DC. It autonomously computes DAR dielectric absorption ratio and PI polarization index, while supporting bulk data logging plus PC‑side data export. Operators can quickly spot insulation dampness, ageing defects or hidden faults, improving test throughput and workplace electrical safety. It fits equipment acceptance procedures, routine industrial upkeep, oil‑field on‑site surveys as well as lab‑based quality assessment tasks.
This rugged tester integrates large backlit LCD, onboard record storage & recall, and auto‑timed data capture for timestamps of 15 s, 30 s, 1 min and 10 min. High resolution readings, simplified wiring workflows and strong electromagnetic noise immunity make it equally suitable for bench‑lab environment and harsh outdoor field assignments. Adopting high‑precision micro‑current measuring circuitry, it features auto test sequencing and persistent measurement logging. Adjustable DC test voltages range 250 V‑5000 V; its resistance measuring envelope stretches 0.01 MΩ‑5.00 TΩ. In parallel, it captures DC voltage (0‑1000 V) and AC voltage (0‑750 V). Common end‑uses cover insulation verification for insulating substrates, power transformers, motors and multi‑core power cables within power, telecom, colocation data hall and oil‑industry domains.
