Calibrate a wide range of pressure gauges and sensors from very low pressure to 3000 psi with this reliable, easy-to-maintain pressure calibrator
Unsurpassed rangeability in one pressure controller / calibrator: install up to five measurement modules with uncertainty as good as 0.01% reading from 30% to 100% of the modules span.
Configure for todays requirements, expand later as your needs change and grow. Add modules to increase the pressure range or accuracy in seconds, without needing to return the instrument to the factory.
Optional contamination prevention system helps you avoid risk of contaminating your pressure standard when calibrating hydraulic devices.
The 6270A features pressure ranges from low differential pressure to 20 MPa (3000 psi), which covers the requirements of most gauges and sensors. Three levels of accuracy, 0.02 % FS, 0.01 % reading from 50% to 100 % or 0.01 % reading from 30 % to 100 %, let you balance your need for accuracy with the limits of your budget.
Thanks to its modular design, the 6270A is flexible enough that you can install modules with different accuracy classes within the same chassis. You can buy the highest level of accuracy for the pressure ranges that require it and a lower, more economical level of accuracy where applicable.
