PR9120Y Full Automatic Hydraulic Pressure Comparator


  • Fast control speed,the pressure reaches a set point less than 20 seconds;
  • Pressure generation for the quickness, stability and non—overshoot,comply with the relevant vertification regulation of pressure instruments.
  • Complete protecting function:When setting pressure above standard,software system will indicate input error,when system pressure accidentally beyond 10% of the standard schedule,the device will stop to pressurize,meanwhile depressurize immediately,to protect the safety of the instrument;
  • Equipment with emergency stop button,quickly depressurize;
  • The data collection,calculation and preservation will be carried out automatically by a computer,The result generated will be printed out as the certificate and report.
  • Mainframe can change more than one range PR9112 smart pressure calibrator to improve the measurement accuracy,convenient for periodic calibration.
  • 14 inch touch screen,built-in windows7 system and the control software,enabling the equipment operating stability, also supporting remote monitoring & maintenance, and software upgrade.
