Fluke 8270A and 8370A Modular High-Pressure Controllers / Calibrators

Widest workload coverage in an automated high-pressure controller

The 8270A and 8370A are automated pneumatic high-pressure controllers that calibrate a wide workload of pressure sensors, covering twice the pressure ranges at twice the speed of other high-pressure controllers.  Two models let you balance price and performance:
  • The 8270A measures and controls pressures from vacuum to 44 MPa (6400 psi).  It can be configured with ranges as low as 100 kPa (15 psi).
  • The 8370A measures and controls pressures from atmosphere to 107 MPa (15 500 psi).  It can be configured with ranges as low as 700 kPa (100 psi).
Fluke Calibration’s unique control technology enables you to use these calibrators at low or high pressures, all in the same instrument. Control precision is 0.002% of active range.
Expand workload coverage to both gas and liquid filled devices by using the optional Contamination Prevention System (CPS).
