| Portable Wh Meter Tester
Three-Phase and Single-Phase Wireless High-Accuracy Field Tester
Safe and fast results, no “strings” attached…
The latest generation of portable meter testers with built-in Wi-Fi technology provides precise data measurement. Our wireless socket-type device, with its dead-front design, attaches quickly and securely to the meter base.
- Powered by a built-in 3-phase phantom load of synthesized 50 A current and an integrated, highly precise watthour standard
- 3-phase reference standard at 0.02% accuracy
- NIST-traceable
- Autodetects various meter forms
- Control the MT-1/WT3 wireless meter tester with the Probewell Connect 2.0 app via the built-in private WiFi network
SKU: WT3
Big technological leaps come in small packages…
Weight: 6.4 lb. | Size: 6.9″ X 6.7″
MT-1/WT3 | Description
