M500 Megohmmeter Insulation Tester MetalBee 20‑1000 Megohms Soft Case

Description

Product Overview

The MetalBee M500 Megohmmeter is engineered for high‑precision insulation resistance testing across a broad range of industrial applications. Capable of measuring from 20 megohms up to a remarkable 1,000 megohms at a safe 500 V AC, this instrument delivers reliable data for diagnosing the health of motors, transformers, HVAC compressors, and related equipment. The device features a rugged ABS double‑sided housing that combines impact resistance with abrasion‑proof performance, ensuring it can survive the rigors of daily field use. A clear, intuitive LCD display incorporates a resistance grading system that instantly categorises results as Good, Normal, or Risk, allowing technicians to make rapid, informed decisions. The M500 includes six‑foot test leads, a soft‑carrying case for secure transport, and a rear panel that opens easily for battery replacement, providing a complete, ready‑to‑use solution for electrical maintenance professionals.

Usage

Designed with versatility in mind, the M500 Megohmmeter excels in a variety of real‑world environments. In HVAC service bays, it quickly assesses compressor windings, detecting insulation breakdown before costly failures occur. Electrical technicians working on motor rewinds rely on its high‑range capability to verify that insulation meets specification after rewinding or repair. Transformer maintenance crews use the meter to perform routine insulation checks on primary and secondary windings, ensuring long‑term reliability of power distribution assets. The portable, battery‑operated design means the device can be taken onto rooftops, into confined plant spaces, or on the road to remote sites without the need for external power sources. Its soft carrying case protects the instrument and accessories during transport, while the ergonomic layout reduces user fatigue during extended testing sessions.

FAQ

What types of equipment can I test with the M500 Megohmmeter?

The M500 is suitable for testing insulation resistance on HVAC compressors, motor windings, transformer windings, control panels, relays, and other electrical components where insulation integrity is critical.

How does the resistance grading system work?

After each measurement, the meter compares the resistance value against predefined thresholds and displays a status of Good, Normal, or Risk, allowing technicians to quickly assess whether the insulation meets safety standards.

What batteries are required and how long do they last?

The M500 uses standard AA batteries (not included). Under typical usage, a fresh set of batteries provides up to 200 hours of continuous operation, depending on test frequency and environmental conditions.

Is the device calibrated before shipping?

Yes, every M500 Megohmmeter is calibrated at the factory to meet industry accuracy specifications. Calibration certificates are available upon request for quality‑controlled environments.

Can I use the M500 for DC insulation testing?

The M500 is designed for AC insulation testing at 500 V. For DC testing, a dedicated DC megohmmeter is recommended to ensure accurate results and safety compliance.
