Automatic Pressure
Calibration System

  • Accurate: 0.1% IV from vacuum to 10,000 psig.
  • Built-in 65 to 250 VAC electrical tester

Model 3689-A
Precision Pressure
Standard System

  • Auto-ranging circuitry permits stepless readings from vacuum to 10,000 psi without operator input.
  • Unparalleled accuracy: 0.025% IV (reading) or 0.001 psi, whichever is greater.

Model 3731
Pressure Calibrator

  • Portable, self-contained calibration system includes all required instruments, hoses, and tools.
  • Calibrates pneumatic gauges from 28.5 in-Hg vacuum to 600 psig (40 Bar).
