What are the pressure range and test medium of the device to be tested?

Once you know which categories of instruments will meet your measurement uncertainty needs and will operate in your environment, you can determine which models in those categories can be used to calibrate your pressure devices, based on pressure measurement mode (absolute, gauge, differential), test medium (gas, oil, water…) and pressure measurement range.

Pressure mode and test medium	Calibration standards typically used	Pressure range covered by calibration standards
Absolute pressure (relative to vacuum) i.e. barometers, altimeters, vacuum sensors, capacitance diaphragm gauges, depth sensors Gas medium, unless otherwise noted	FPG8601 force-balance piston gauge	0.001 to 2.2 psi (5 Pa to 15 kPa)
	PG7601 and 2465 absolute piston gauges	0.2 to 1000 psi (1.5 kPa to 7 MPa)
	PPC4 and 7250 pressure controllers	<1 to 3000 psi (<7 kPa to 20 MPa)
	RPM4 and 7050 gas pressure monitors	<1 to 15k psi (<7 kPa to 100 MPa)
	* PG7102, PG7202 and 2470 piston gauges	0.2 to 15k psi (1.5 kPa to 100 MPa)
	** PPCH-G and 7350 pressure controllers	15 to 15k psi
	*** PG7302 and 2485 hydraulic piston gauges	15 to 75k psi (100 kPa to 500 MPa)
	** PPCH and 7615 hydraulic pressure controllers	15 to 40k psi (100 kPa to 280 MPa)
	** RPM4 hydraulic pressure monitors	15 to 40k psi (100 kPa to 280 MPa)
	Fluke handheld process calibration tools	<1 to 100 psi (<7 to 700 kPa)
	Absolute pressure by adding barometer reading to gauge pressure – cannot measure below atmospheric pressure. High pressure controllers and hydraulic pressure monitors available with absolute pressure measurement, but cannot control below atmospheric pressure. **Use hydraulic medium, absolute pressure by adding barometer reading to gauge pressure – cannot measure below atmospheric pressure.
Gauge pressure (relative to atmospheric pressure) Gas medium	PG7601, PG7102, PG7202 and 2465, 2468, 2470 gas piston gauges	0.2 to 15k psi (1.5 kPa to 100 MPa)

Gauge pressure (relative to atmospheric pressure) Fluid/hydraulic medium	PG7302 and 2485 piston gauges	<15 to 75k psi (<0.1 to 500 MPa)

	Fluke handheld process calibration tools	<15 to 10k psi (<0.1 to 70 MPa)
	NOTE: Zero gauge pressure on all standards by venting system.
Negative and bidirectional gauge(relative to atmospheric pressure, includes measurement below atmospheric pressure) Gas medium	FPG8601 force-balance piston gauge	±2.2 psi (±15 kPa)
	* PG7601 and 2465, 2468 piston gauges	-15 to 1000 psi (-100 kPa to 7 MPa)
	PPC4 and 7250 pressure controllers	-15 to 3k psi (-100 kPa to 20 MPa)

	Fluke handheld process calibration tools	-15 to 300 psi (-100 kPa to 2 MPa)
	NOTE: Zero gauge pressure on all standards by venting system. Where -15 psi (-100 kPa) is indicated, actual minimum negative gauge pressure depends on atmospheric pressure. *Requires differential mode – consult Fluke Calibration product application specialist
Differential pressure (relative to identified line pressure, devices typically have a reference and test pressure ports)	FPG8601 force-balance piston gauge, gas line pressure near vacuum or atmosphere	<±0.0001 to ±2.2 psi (<±1 Pa to ±15 kPa)

	NOTE: Zero differential pressure on all standards by bypassing high and low pressure lines.

Note: Fluke Calibration also offers fluid separators and differential pressure cells. These devices may require additional work or introduce greater reference uncertainty, but can often be utilized to allow different mediums in the reference standard and device under test.
