M500 Megohmmeter Insulation Meter by Caviartool 500V 1000MΩ

Description

Product Overview

The M500 Megohmmeter is a purpose‑built insulation resistance meter designed for accurate, high‑voltage testing in industrial and field environments. Engineered by Caviartool, the device offers a measurement range from 20 MΩ to 1000 MΩ, allowing technicians to verify the integrity of cables, transformers, motors, and other electrical components with confidence. The built‑in 500 V test voltage provides a safe yet powerful excitation source, while the dual‑C‑battery power system ensures long operational life without frequent recharging. Its rugged housing meets IP‑rated protection standards, resisting dust, moisture, and accidental drops. The back panel is removable, providing dedicated storage for two 6‑inch test leads, which are included in the package along with a soft carrying case and a comprehensive operating manual. Dimensions of 1 × 6 × 6.9 inches and a weight of just 10.86 oz make the M500 easy to carry in a tool belt or toolbox, while the intuitive digital display presents clear readings in megohms, eliminating guesswork and reducing the chance of human error.

Usage

The M500 excels in a variety of real‑world scenarios. Electrical maintenance crews use it to perform routine insulation checks on HVAC systems, ensuring that coils and windings remain free of moisture and contamination. Power plant operators rely on the meter for pre‑shutdown verification of generator windings, where accurate megohm readings are critical to prevent costly equipment failures. Field service engineers appreciate the portable design when troubleshooting motor failures on remote sites, where quick access to a reliable insulation tester can mean the difference between a fast repair and prolonged downtime. Safety inspectors also benefit from the device’s ability to quickly assess grounding integrity in commercial buildings, confirming that protective earth paths meet regulatory standards. The removable back panel and included test leads simplify set‑up, while the soft case protects the instrument during transport between job sites.
