Description
MT-1/NT9
Portable 3-phase watthour meter tester
The MT-1/NT9 is an all-in-one portable meter tester with advanced features such as VARh testing, kW demand test, THD consumer line monitoring and bi-directional testing for Net Metering installations. No other equipment needed.
A fast and accurate test is done within a few minutes! No setup wiring necessary. The MT1/NT9 is a full-featured tester at a budget-friendly price!
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.
Uncompromised accuracy
Three built-in 50A current synthesizers (phantom load) simulate active and reactive load.
Its built-in three-phase Wh/VARh standard will offer you a typical NIST traceable accuracy of ±0.02%.
Highly Compatible
You can test commercial and industrial three-phase meters along with residential meters.
Easily configurable with twist & lock removable tabs, you will be able to test both solid state and electromechanical meters.
