Model 3689-A Precision Pressure Standard System

Model 3689-A Precision Pressure Standard System
Description:

The model 3689-A Precision Pressure Standard system by King Nutronics Corporation is based on a digital pressure transfer standard that is unmatched in the industry for its accuracy: ± 0.0025% IV (read.) or 0.001 psi, whichever is greater. Auto-ranging circuitry incorporated in the Model 3689-A Precision Pressure Standard enables stepless readings from vacuum to 10,000 psi without input form the operator, preventing damage to the instrument due to the over-pressurization of the transducers. The Model 3689-A Precision Pressure Standard displays direct reading measurements using a wide range of units, including psi, in-Hg, kPa, bar, in-H20, and ft./seawater. Three measurement modes are available: absolute mode, gauge mode, and vacuum mode.

Model 3689-A Precision Pressure Standard System
Features:
  • Unmatched in industry for its accuracy: ±0.025% IV (read.) or 0.001 psi, whichever is greater.
  • Auto-ranging circuitry enables stepless readings from vacuum to 10,000 psi, preventing damage to the instrument due to the over-pressurization of the transducers.
  • Displays direct reading measurements using a wide range of units including psi, in-Hg, kPa, bar, in-h2O, and ft/seawater.
  • Three measurement modes are available: absolute mode, gauge mode, and vacuum mode.
  • A microprocessor control and front panel display prompts the operator through the calibration and standardization process and performs the necessary calculations, saving time and effort.
  • An integral IEEE-488/GPIB interface enables automated calibration and standardization of the KNC Model 3666 system and can be used to transmit data to a remote computer.
  • A built-in printer conveniently generates permanent records of measurement data.
  • Includes a liquid trap, a kit containing 12 male and female quick-disconnect adapters from 1/8 to ½-inch diameter, a MIL-I-18997C Adapter, and a packing kit containing back-up rings, seals and other supplies necessary for field maintenance of the pressure standard and liquid trap.
