MT-1/NT5
Portable Single Phase Watthour Meter Tester



The MT‐1/NT5 can test two phases simultaneously or separately, for commercial dual phase meters (5S, 12S, 35S and 45S). The meter under test is entirely controlled by the test socket. No wiring setup needed.

Perfect for Single-Phase
A complete tester for all your single-phase watthour testing needs, the MT-1/NT5 also has bi-directional testing capability for net-metering installations.

Uncompromised accuracy
Three built-in 50A current synthesizers (phantom load) simulate active and reactive load.
Its built-in single-phase Wh/VARh standard will offer you a typical NIST traceable accuracy of ±0.02%.

Easy Setup
Fast setup with no wiring and a dead-front design means your operation is quicker and safer.
Setting-up your test has never been easier.
