Choose the modules
The 6270A is now available with three types of pressure measurement modules, giving you even more ways to balance accuracy and workload coverage with expense.
Compare the PM200, PM500 and PM600 Pressure Measurement Modules
Good: PM200 Pressure Measurement Modules
0.02 % FS specification makes it ideal for calibrating or testing pressure dial gauges, lower accuracy transmitters, or pressure switches.
Better: PM500 Pressure Measurement Modules
0.01 % reading measurement uncertainty from 50% to 100% for most ranges provides 2x the accuracy at full scale and 4x the accuracy at mid-scale compared to the PM200.
Best: PM600 Pressure Measurement Modules
0.01 % reading measurement uncertainty from 30 % to 100 % of the modules’ span allows for extremely wide workload coverage.

Compare the measurement range options
Good: PM200 Pressure Measurement Modules
21 measurement ranges from -100 kPa to 20 MPa (-15 to 3000 psi) enable you to cover a basic workload or pressure gauges and sensors.
Better: PM500 Pressure Measurement Modules
More than 45 ranges, from -100 kPa to 20 MPa (-5 to 3000 psi) to choose from. More ranges give you more flexibility to match pressure range to device under test.
Best: PM600 Pressure Measurement Modules
14 ranges from -100 kPa to 20 MPa (-5 to 3000 psi) including modules that are inherently absolute mode and gauge mode.
The absolute mode modules include an onboard barometer to provide dynamic compensation of changes in atmospheric pressure, so you can use the modules in both absolute and gauge mode.
Compare the prices
Good: PM200 Pressure Measurement Modules
Economic price point means you can afford more modules, including backup modules that you can swap out to avoid downtime during module calibration.
Better: PM500 Pressure Measurement Modules
You can get the improved accuracy and flexibility of the PM500 for almost a third of the price of a PM600 module.
Best: PM600 Pressure Measurement Modules
The PM600 modules are premium solutions for calibration professionals who need the best uncertainties.
