| Three-Phase Wh Meter Tester
High-Accuracy Portable Field Meter Tester
Perform an accurate meter test in just a few minutes!
Probewell’s MT-1/NT9 has a built-in 3-phase phantom load made of synthesized 50 A current sources and a 3-phase electronic standard with an accuracy of ±0.02% typical, ±0.05% guaranteed.
Net metering-enabled
The MT-1/NT9 is a bidirectional meter tester and can perform reverse power flow testing in solid-state meters devices meaning that it can perform net metering tests on the installation.

MT-1/NT9 | Description
Probewell’s MT-1/NT9 is among the most advanced portable three-phase watthour meter tester
The MT-1/NT9 test socket adapter weighs only 6.4 lb, an ideal tool for testing in the field and in the meter shop. Within a few minutes, a residential, commercial or industrial electricity meter can be accurately tested on site by meter shop technicians. The MT-1/NT9 can be set to test all 3 phases simultaneously in one step (Mode Preset-quick) or set to do a full test consisting of the 3 phases simultaneously followed by each element separately (Mode Preset-full).
Furthermore the MT-1/NT9 is a portable three-phase meter tester that tests self-contained and CT rated meters forms, such as 1S, 2S, 3S, 4S, 6S, 8S, 9S, 12S, 14S, 15S and 16S.
