Neutral Supply Tester NST M1120-V2-B (VIC, SA, NT, QLD, TAS) – Dewar MET-D-M1120-V2-B

Description

Dewar Neutral Supply Tester for Professional Electrical Testing

The Dewar Neutral Supply Tester NST M1120-V2-B (MET-D-M1120-V2-B) is designed to help electricians determine whether an electrical supply presents a safe or unsafe condition. It measures voltage, impedance and polarity in relation to Active, Neutral and Earth connections, making it suitable for industrial, commercial and domestic applications.

Designed specifically for use in Victoria, South Australia, Northern Territory, Queensland and Tasmania, the NST provides a practical solution for professionals who need dependable supply testing equipment on the job. Testing is performed over four full 50Hz cycles, while the microprocessor-controlled system is designed for high accuracy and reliability.

Clear Testing Results and Practical Operation

The tester provides straightforward results through its two-line LCD and three status LEDs for Power, Pass and Fail. An audible alarm also alerts the user when the unit fails a test, helping make test outcomes easier to identify in busy work environments.

The NST is powered directly by the user’s connection to the instrument, eliminating the need for batteries or battery replacements. Bluetooth functionality through the NSTLINK App allows test results to be saved and emailed for convenient record keeping.

Built for Electrical Trade Conditions

The high-strength plastic enclosure features a shatterproof decal and is designed to withstand a 6m drop. The unit also incorporates automatic lockout protection if its internal reference resistor overheats during repeated testing.

It can withstand accidental connection across three phases at 415V and includes a CAT IV 1kV probe, double-insulated flexible test probes and a 32mm-jaw crocodile clip. The tester is designed and manufactured in Melbourne, Australia.
