Intelligent Electrical Equipment Calibration Measuring CT Variable Ratio Long Lifespan
Electric Meter Calibration Equipment With Printer Accuracy 0.05 for Check of Electricity Meters
GF312B portable three phase Energy Meter Calibration Equipment with printer is used to calibrate three phase, single phase, active and reactive watt meters. And it also can be used as voltage, current and power meter to measure AC parameters of three phase power line.It can measure wave distortion factor and 2nd to 63th harmonic wave. it is high precision 0.05%, measurement current 0-24A directly, 0-120A or 0-3000A with clamp on ct. 100A clamp on ct has software compensation, the precision can reach 0.05%.
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.
