Product Introduction

The MOEORW‑W1350A is a compact, high‑precision digital insulation resistance tester built for field inspection and routine maintenance across power, telecom, oilfield, electromechanical, and data center environments. It delivers multi‑level high‑voltage insulation testing, AC/DC voltage measurement, and automatic PI/DAR analysis to quickly judge insulation health, prevent leakage and breakdown risks, and secure electrical safety during installation, handover, and upkeep tasks.
