GF312D1 0.05% Accuracy 576V 120A Portable Three Phase Electric Meter Calibrator With 100A clamp on ct
GF312D1 Portable Three Phase Electric Meter Calibrator With 100A clamp on ct is a precision AC energy meter testing instrument, mainly used to test three phase energy meter error on site and measure all various of AC parameters.
Calibration of electricity meters An electricity meter or a watthour meter measures the electrical energy passing through the meter and may be single-phase or poly-phase.
Application
The devices used to calibrate electricity meters must be routinely verified themselves. That’s the only way to protect consumers. Laborelec’s working standards are well suited to the task. We can carry out calibration on your site, minimising disruption to your calibration routine.
Laborary has a fully equipped calibration equipment with the most accurate energy standard. It can furnish an extensive accreditation portfolio that is recognised internationally.
