GFUVE GF112B 120A 300V 0.02% Handheld Single Phase Reference Standard Meter
SINGLE PHASE REFERENCE STANDARD METER- SPRS The Single Phase Portable Reference Standard (GF112B) from GFUVE is a hand- held device that helps to calibrate the error present in the single phase energy meter i.e. the meter under test (MUT). The GF112B supports both static and electro-mechanical types of meters.
Single Phase Reference Standard Meter. GF112B is high precision Single Phase Reference Standard Energy Meter and it has high speed DSP as the main processor. It uses the advanced technology and latest electronic components for higher accuracy measurement of power, energy, voltage, current, phase angle, frequency and better stability.
Established in 2005, GFUVE is well-known as one of the leading and professional manufacturers and suppliers of high performance-price ratio 0.1 accuracy class stationary single-phase reference standard meter with measurement current range 1ma – 120a, test of voltage 0v - 480v , with large size lcd display screen in China.
