Probewell MT-1/NT3 Meter Tester The third generation of
our very popular MT-1/NT with 3-phase capability!

It is an ideal tool for field-testing and periodic sampling. The meter under test is entirely controlled by the test socket. No setup wiring is needed. A complete test is done within a few minutes!

The MT-1/NT3 can test forms 12S, 14S, 15S and 16S self-contained 3-phase Wh meters along with single-phase forms 1S and 2S.

The MT-1/NT3 can be set to test all 3 phases simultaneously in one step (Mode Preset-quick) or set to do a full test consisting of 3 phases simultaneously followed by each element separately (Mode Preset-full). The MT-1/NT3 has also reverse flow testing capability for solid-state Wh meters.

  • Comes with a complete calibration report certifying measurement accu-racy over its entire 36-point operating range using a primary standard traceable to NIST.

  • A specially designed removable tab with a twist and lock mechanism can be easily moved by hand at 5, 6 or 9 o'clock.

    In addition to standard test results and answers to personalized questions, NTDataOne automatically transfers such fields as: Standard's serial number, remote serial number, meter forms, Kh, and much more. The main advantage of using .CSV files is that column width can be automatically set in seconds. Data can be viewed on Excel only seconds after coming in from the field. This format can then be transferred to any data management software.
