Megger LTW335 Loop Tester

The Megger LTW335 Loop Tester is designed for professionals who need reliable, accurate, and efficient earth loop impedance testing. Equipped with built-in memory, this model allows users to store and download results, eliminating the need for manual recording. It supports two-wire testing, enabling fast and safe measurements without disconnecting the supply. Its compact and durable design makes it an excellent choice for frequent on-site testing, ensuring accuracy in various electrical environments.

Advanced Non-Trip Testing and Noise Filtering

This tester features a full non-trip loop test, ensuring it does not trip RCDs of 30mA or greater. The Megger LTW335 Loop Tester also includes a high-current loop test for situations where RCDs are not present. Its advanced noise detection circuitry filters out electrical interference, improving measurement accuracy. The auto-start function further enhances efficiency by initiating tests as soon as the probes are connected.

Built for Versatility and Ease of Use

Designed to work with voltages ranging from 50V to 440V, this tester supports phase-to-phase testing and is three-phase safe. It is rated for CAT IV 300V, ensuring high safety standards for various applications. The device also features an auto-start loop test, backlit display, and IP54-rated weatherproof casing for use in demanding environments. The Megger LTW335 Loop Tester provides fast and precise measurements, helping electricians diagnose electrical faults with confidence.

The Megger LTW335 Loop Tester is ideal for electricians and engineers performing regular loop testing across multiple sites. Its compact design, rechargeable battery compatibility, and included test leads make it ready to use straight out of the box.
