GF312B 120a clamp on ct Three Phase Portable Electric Energy Meter
Calibration Device With Printer
GF312B Portable Electric Energy Meter Calibration Device 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%.
GFUVE Electronics is a recognized world leader of Energy Reference
Standards, Meter Test Boards, CT / PT Meter Field Testers, DC / AC
Transfer Standards, Energy Meter Testing and our Automated
Laboratory Energy Reference Systems. GFUVE Electronics is 100%
committed to exceeding the requirements of its Customers through
continual improvement of all our products and services.
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.
