The 8370A measures and controls pressures from atmosphere to 107 MPa. It can be configured with ranges as low as 700 kPa.
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. For example, an 8370A with a 70 MPa high range module and a 700 kPa low range module will be able to control pressures below 700 kPa to within ±0.014 kPa without reducing the supply pressure.

Flexible configuration options
The 8370A are modular system 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.

Safety is the top priority in the design and manufacture of our pressure products, especially high-pressure pneumatic controllers. The 8370A meet all appropriate safety standards. Each unit is equipped with over-pressure protection as well as a frontpanel 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 8370A with the available accessories, you have safe operation with a clean pressure media.

Calibrate without risk of contamination
The 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 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 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 lines
Whether you manufacture large batches of low cost pressure sensors or customized, expensive pressure sensors for aerospace and other mission critical applications, the 8370A  are ideal for use in your production line.
