1500-8.5I Pressure Indicator Gauge


  • Test, laboratory, and production applications

Product features

  • These gauges have capsule-type pressure elements up to and including the 150-psig ranges of 200 psig and above have Bourdon tubes
  • The pressure to be measured is applied to the capsule or Bourdon tube through a single connection in the case
  • The case has a tempered-glass dial cover, solid-front dial and a blow-out plug on the back
  • Readings are referenced to atmospheric pressure in the case
  • Available in 26 standard ranges (including vacuum and compound ranges), these gauges combine precision-liquid-column accuracy with aneroid convenience
  • They make excellent secondary standards and are rugged enough to maintain accuracy in many test and process applications
