Description
Accurate Electrical Supply Testing
The Neutral Supply Tester uses microprocessor-controlled technology to deliver accurate and reliable test results. Testing is carried out over four full 50Hz cycles, while the easy-to-read two-line LCD displays the measured results. Three status LEDs clearly indicate Power, Pass and Fail, with an audible alarm providing an additional indication when a test fails.
The unit is powered directly through the user’s electrical connection, removing the need for batteries or battery replacements. It can also withstand accidental connection across three phases at 415V, adding protection against common connection errors during testing.
Durable Design and Digital Results
Built for demanding trade environments, the NST features a high-strength plastic enclosure with a shatterproof decal designed to withstand a 6 m drop. An automatic lock-out function protects the instrument if its internal reference resistor overheats during repeated testing. Bluetooth functionality allows the NSTLINK App to save and email test results, making it easier to retain testing records and share results when required.
Built for Professional Electrical Work
The Dewar NST M1121-V2-B combines clear test indication, durable construction and digital record-keeping in a compact instrument suited to professional electrical work. Its protective features and direct-connection power design help minimise maintenance requirements while supporting efficient testing on site.
