Profile:

The KDJD-D is an intelligent SF6 density relay calibrator designed for on-site testing. It uses high-precision pressure sensors and a 32-bit microcontroller to automatically convert pressure to 20°C standard values, eliminating manual calculations. It measures alarm/lock values, supports single/dual-point testing, and includes pressure gauge calibration. With a 320×240 LCD, one-knob operation, built-in printer, and USB data transfer, it streamlines calibration workflows while ensuring 0.2-class accuracy and reliability.

Features:

  • High-precision imported core components for stable, repeatable measurements.
  • No constant temperature room required; automatic pressure-temperature compensation.
  • Tests 1 group of alarm signals and 2 groups of lock signals simultaneously.
  • Intuitive Chinese LCD interface with one-knob operation for easy parameter adjustment.
  • Multiple adapter heads enable non-disassembly testing of most SF6 density relays.
  • Low SF6 gas consumption during testing, reducing costs and environmental impact.
  • Built-in data storage (50 groups) and USB transfer for historical data access.
  • Supports Chinese report printing and PC software for data analysis.
  • Online clock modification and fault auto-detection for convenient maintenance.
