Model 3689-A Precision Pressure Standard System Features
• 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.

• Displays direct reading measurements in: psig, psia, in-Hg, mm-Hg, kPa, kg/cm2, bar, mbar, in-H2O, ft-H2O, ft/seawater, feet (barometric), and meters (barometric).

• Three measurement modes available: Absolute mode, Gauge mode, and Vacuum mode.

• Integral IEEE-488/GPIB interface enables automated calibration of the KNC Model 3666 Automatic Pressure Calibration System and transmits test data to a remote PC compatible computer.

• Microprocessor control and front panel display prompts the operator through the standardization and calibration process.

• Built-in printer generates convenient hard copies of measurement data.

• Includes a liquid trap, male and female quick-disconnect adapters from 1/8" to 1/2" diameter, a MIL-I-18997C adapter, and a packing kit for field maintenance of the pressure standard and liquid trap.
