Wholesale Megger MOM3 Handheld micro-ohmmeter Manufacturer, Supplier

Overview

The Megger MOM3 Handheld Micro - ohmmeter is a high - performance instrument designed for low - resistance measurement. Here is an overview:

Product Design

Portable and Durable: Weighing 1.15 kg, it has a compact size of 230 × 108 × 98.5 mm. The rubber - coated body provides good drop resistance, and it has an IP54 protection level, making it suitable for fieldwork in various environments.

Battery - powered: It is equipped with a 19.8Wh lithium - ion battery, which supports 2000 tests at 50A, 1500 tests at 100A, or 500 tests at 300A. The battery can be fully charged in 3 hours at 25°C, and the charger input is 100 - 240V AC, 50/60Hz.

Technical Features

Measurement Range and Accuracy: The measurement range is 0.1 μΩ to 3000mΩ with an automatic - ranging function. The accuracy is ±0.1% of the reading ±0.05% of the range, ensuring high - precision measurement results.

Output Current: It can output a maximum DC current of 300A (when the load resistance is ≤2mΩ), which is generated by two built - in ultracapacitors. The ultracapacitors can store a large amount of energy and deliver a high - current output instantaneously due to their low internal resistance.

Measurement Time: The measurement time is as short as 5 seconds, which can avoid the heating of the measured object and eliminate the need for bidirectional measurements commonly used in micro - ohm measurements.

Data Management

Data Storage: It can store more than 2000 groups of data, including test results and related parameters.

Data Transfer: Data can be transferred to a PC via a USB - C interface for further analysis and processing. Additionally, Wi - Fi functionality will be available from Q4 2025, enabling more convenient data transmission.

Safety and Compliance

Safety Design: The instrument has a V0 - grade fire - proof shell, which meets safety requirements. It also complies with IEEE and IEC standards and has CE certification, ensuring its reliability and compliance in various applications.

Application Scope

Electrical Equipment Testing: It is mainly used for measuring the resistance of key electrical components, such as circuit breaker contacts, busbar joints, switches, grounding devices, welds, fuses, and cables. It is applicable to the inspection and maintenance of low - voltage, medium - voltage, and high - voltage electrical equipment.
