Choose the modules
The 2271A is now available with two types of pressure measurement modules, giving you even more choices to balance accuracy and workload coverage with expense.
Compare the PM200 and PM500 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.

Compare the measurement ranges
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 of pressure gauges and sensors.
Better: PM500 Pressure Measurement Modules
46 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.
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’ll spend more for this module but you’ll get a significant boost in accuracy and flexibility. Choose the solution that best fits your workload and budget.
