CH-11 high-accuracy standard capacitors

  1. CH-11 high-accuracy standard capacitor is a high-stability, low-loss capacitor which is made of the well-selected, high-quality quartz and nanometer ceramics materials through special processing. The capacitor is installed in a thermostatic chamber with excellent thermo insulation, and the temperature is accurately controlled through microelectronics automatic control technology to keep the capacitor at a very stable temperature. Therefore, the capacitor has achieved extremely high accuracy, high stability, and resistant to environment change.
  2. CH-11 high-accuracy standard capacitor can be used for verification and calibration of various high-accuracy LRC measuring instruments and digital capacitance bridges. It is an ideal standard capacitance measuring instrument for metrology institutes, research institutes, factories, universities, and etc.
