Product Description

GF333 Portable smart three phase reference standard

(Accuracy class 0.02%/0.05%) 


GF333 multi-function standard meter, its core part uses the DSP 32 bit and16 bit low power and high speed DAC consists of high accuracy AC collector. Not only it can be used as a calibration device standard meter, but also it can be used as a testing calibrator. Using 6.5 inch TFT color LCD screen, character display clear chart. Have the advantages of wide measuring range, high precision, stable and reliable operation, simple operation etc.


It is suitable for Grid Corporation measurement test center, the power company and power plant measurement department, national levels of measurement mechanism, quality inspection departments, research institutes, tertiary institutions, industrial and mining enterprises, electric energy meter and electrical instrument production enterprises etc.

Functions and Features 

1. Measure the AC voltage, current, active power, reactive power, frequency, phase angle and power factor etc;

2. Measure the AC voltage, current 2-31 harmonic content and waveform distortion degree;

3. Measure active power energy error, reactive power energy error, the maximum output pulse frequency is to 2 MHZ;

4. Measure calibration device of voltage, current, power stability;

5. Measure calibration device the standard deviation of estimate;

6. Measure the voltage of the calibration device three-phase symmetric degrees, the current of three three-phase symmetric degree;

7. Measure calibration device of the magnetic induction;

8. Measure DC voltage and DC current;

9. Transducer measurement;

10. With RS232 interface, it can be controlled by PC operation;
