Portable 3-phase wireless watthour meter tester
for instant results
Our wireless socket-type device, with its dead-front design, attaches quickly and securely.
- Powered by a built-in 3-phase phantom load of synthesized 50 A current source and an integrated highly precise watthour standard
- 3-phase reference standard at 0.02% accuracy
- Autodetects various meter forms
Like all our wireless products, the meter tester can be paired with a mobile device in seconds by scanning its QR code while using the Probewell Connect app.
SIZE: 6.9″ X 6.7″
WEIGHT: 6.4 lbs
Speed up your 3-phase testing
Wh & VARh testing, kW demand test, line monitoring with THD analysis and bidirectional testing
for Net Metering installations directly on your mobile device or laptop.
No wires, no problems
Fast twist & lock tab setup with no wiring and a dead-front design means your operation is quicker and safer.
Setting-up your test has never been easier; you’ll be testing in no time.
You can test residential, commercial and industrial single & three-phase meters. Easily configurable with twist & lock removable tabs, you will be able to test both solid state and electromechanical meters.
