GDFR-D series Integrative digital high-voltage meter

GDFR-D series Integrative digital high-voltage meter

General introduction

GDFR-D series digital HV meter is designed by integrating RC voltage divider and high resistance digital meter, realizing high voltage measurement and display. Customer can choose different accuracy as per the precision requirements of testing voltage.The highest accuracy are AC:0.5% DC:0.5%. If higher accuracy is needed, please choose our AC/DC calibration standard with high accuracy and stability;Adopted with potential shielded HV measuring device, its our newly developed product. Compared with other similar products, it uses American imported filling materials and various patent shielded technology inside, which makes this series products have longer life time and higher stability. It occupies the majority of market share and wins a wide user recognition.

Features

  • Adopt balanced equal potential shielding structure
  • The completely sealed insulating cylinder adopts high-quality electronic components, which makes the whole device have accurate testing results and good linearity.
  • With high precision, high linearity, high stability and strong anti-interference ability;
  • Display instrument and high-voltage cylinder are integrated into one, and theres no need to connect instrument. People can read data at a long distance, which is more safe and convenient.
  • Small volume and light weight, is easy to carry. It is suitable for on-site inspection.
  • Inner shielding anti-interference system, omnibearing voltage-sharing measurement;
  • Can choose to increase peak value;
  • With infrared data transmission function, makes HV measurement and control are isolated completely (its optional)
