New Megger(R) Insulation Tester


Designed to maximize the features that are of real benefit to the electrical contractor or service engineer, the new MEGGER BMM503 triple voltage Insulation/Continuity Tester comes with a unique Instant Response 'ZAP' Buzzer and Intelligent Safety System.

The buzzer, with an instant response 80 times faster than its competitors that can take up to 1 second to respond, has 7 user selectable thresholds, below which the buzzer will sound continuously. The instrument is frequently used for checking for correct polarity in installed circuits and for point-to-point connectivity in servicing where an instant response is vital.

Another unique feature is the product's Intelligent Safety System, designed to provide additional protection, and containing a live circuit warning, safe contract detector, test lockout, default voltmeter and auto discharge. This eliminates damage to the instrument and the operator from being exposed to danger due to occasional mistakes that may occur as a result of tests being performed in time-pressured situations.

The BMM503 is microprocessor controlled, easy to operate, has a large clear backlit display, and ensures outstanding performance. For ultimate reliability it is waterproof and dustproof to IP54 and supplied with a 3-year warranty.

The product has a wide variety of applications for testing electrical installations and gives the electrical contractor a highly functional tool for testing/commissioning fixed installations. Within the service industry it offers a comprehensive range of features in a single unit where the insulation ranges are useful for establishing the integrity of the internal parts such as motors, timers and transformers, while the continuity range can verify the correct earth bonding within areas such as case metalwork.
