MT-1/NT9

Ultimate All-in-one

The MT-1/NT9 is the ultimate 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. The test socket weighs only 6.4 lb!
A fast and accurate test is done within a few minutes! No setup wiring necessary. It is an ideal tool for field testing and periodic sampling and can also be used instead of a test board in the metershop.
The MT-1/NT9 can test commercial and industrial 3-phase meter forms 6S, 8S, 9S, 12S, 14S, 15S and 16S along with residential meter forms 1S, 2S, 3S, 4S and 12S(N).
The MT-1/NT9 comes with a complete calibration report certifying accuracy for both Wh and VARh scales over the entire operating range using a reference standard traceable to NIST.
Full-featured tester at a budget-friendly price!
