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).
100:1 control turndown
A pressure range 100 times smaller than the full scale will meet the control specifications without reducing supply pressure. For example, an 8370A with a 70 MPa (10 000 psi) high range module and a 700 kPa (100 psi) low range module will be able to control pressures below 700 kPa (100 psi) to within ±0.014 kPa (0.002 psi) without reducing the supply pressure.
Flexible configuration options
The 8270A and 8370A are modular systems that can be configured with up to five measurement modules at the same time, so they can handle high pressure, low pressure, and everything in between. Three families of modules provide three levels of performance that let you set up a system matching your needs for accuracy and value.

Modern replacements for hydraulic deadweight testers and comparators
Safety: the number one priority
Safety is the top priority in the design and manufacture of our pressure products, especially high-pressure pneumatic controllers. The 8270A and 8370A meet all appropriate safety standards. Each unit is equipped with over-pressure protection as well as a front-panel abort button. Pressing the abort button vents the test pressure and returns the unit to a safe condition. Additionally, an abort valve accessory allows for faster, directed vent, as well as automated venting at loss of power. High-pressure gas does have more stored energy than high-pressure oil, but it is a safe option under the right conditions. By using the 8270A or 8370A with the available accessories, you have safe operation with a clean pressure media.
Calibrate oil or gas devices without risk of contamination
The 8270A and 8370A, coupled with the optional CPS, can calibrate both gas-filled and liquid-filled devices without concern of contamination. With its wide pressure range coverage, one controller can accomplish the task that used to require two separate standards.
Easiest to use high-pressure standards available
Automated pressure controllers are some of the simplest, easiest-to-use pressure standards. Controlling and measuring pressure is as simple as typing in the required pressure and pressing Enter. Unlike deadweight testers, you do not need to spin weights at a particular speed or calculate gravity or temperature corrections. Unlike pressure comparators, the process can be fully automated and stability is achieved and maintained in a fraction of the time.
Flexibility to handle a wide variety of applications and workloads
The 8270A and 8370A can be configured with different classes of modules with different pressure ranges. This gives you flexibility to handle a variety of applications and workloads. Uncertainties as good as 0.01 % reading are available across the vast majority of the range, making it an ideal replacement for deadweight testers.
An affordable solution that can grow as your requirements do
With their wide pressure range coverage, the 8270A and 8370A can replace multiple standards at once. Thanks to the modular design, pressure ranges and capabilities can be added at any time, allowing for lower cost of entry in favor of future expansion, growing with your needs.
Ideal for characterization or calibration in production processes
Whether you manufacture large batches of low cost pressure sensors or customized, expensive pressure sensors for aerospace and other mission critical applications, the 8270A and 8370A are ideal for use in your production line.
Robust design provides unsurpassed control performance
The 8270A and 8370A make use of our unique pressure control technology, first developed to handle some of the harshest pressure calibration applications. This technology provides unsurpassed control performance over a wide pressure range over an extended life cycle, reducing your downtime and maintenance costs.
Modularity makes maintenance a snap
The 8270A and 8370A make use of Fluke Calibration’s modular platform design. Measurement and control modules can be easily removed through the front panel to simplify maintenance or re-ranging requirements.
Control speed meets the demands of a manufacturing environment
With times to setpoint as low as 30 seconds, the 8270A and 8370A can control pressures faster than traditional high-pressure controllers can.
Support for remote communication and automation
The 8270A and 8370A support remote communication over RS-232, GPIB, USB, and ethernet connections. Using either the native SCPI protocol or a variety of emulation modes, these controllers can be used in a wide range of automated processes.
Clean operation to 100 MPa (15 000 psi)
The wide pressure range control allows you to use the same test station for low, medium, or high-pressure work. By using a pneumatic pressure controller in your production process, you can provide your customers with a clean product, free of oil contamination.
Automate with COMPASS® software
COMPASS for Pressure software enables you to automate the 8370A and 8270A and run complete pressure calibration sequences on single or multiple devices under test (DUTs). The 8270A and 8270A feature a full remote interface that also lets you use it with custom software or other data acquisition equipment.
Support and services when you need them
Fluke Calibration offers testing, repair and calibration services to meet your needs quickly and at a fair cost while maintaining the high level of quality that you expect. Our pressure calibration laboratories are accredited for conformance to ISO Guide 17025 and we maintain global calibration and repair facilities.
