In today’s high-tech meter shops and high-output manufacturing plants getting an accurate meter test fast increases overall workflow, keeping your company operating in the black. Watthour Engineering’s line of premier test equipment combines a quarter century of meter industry experience with a vision of innovation to bring you industry leading test solutions.

The Model 2350 sets the benchmark for precision and functionality in today's meter testing industry. This versatile testboard provides fully ANSI compliant testing using either a single, or three-phase voltage and current up to 50 amps. Three-phase power combined with the file/graph capabilities of WECO's Winboard™ software gives you the power to test today's meters with any combination of voltage phase angles, current imbalances, phase angle imbalances and frequencies in .001Hz steps. With the revolutionary Turbo Test™ option, you can run simultaneous series and element tests, and increase the productivity of your meter shop five-fold*.

WECO's advanced laser optics system is safe but powerful enough to drive through the dirtiest covers while still delivering the precision you demand. Coupled with three removable Radian Research™ digital standards, the Model 2350 boasts unparalleled traceability, reliability, and accuracy. This testboard package is rounded out with WECO's Smart Socket™ technology, KYZ inputs, optional barcode scanner, optional Optic Coupler system, plus a two-year warranty†. The Model 2350 is the ideal tool for today’s cutting-edge meter shops or manufacturing environments.
