The Martel BetaGauge 301 is a single sensor pressure calibrator offering great performance at a great price. The BetaGauge
301 combines pressure with milliAmp and Voltage measurement capabilities, as well as a built-in loop power supply to
power transmitters under test.
The BetaGauge 301 is available in pressure ranges of 1, 5, 30, 100, or 300 psi. With the optional BPPA-100 adapter, the
Martel 301 can be configured for an even wider range of pressures using industry standard BetaPort–P high performance
pressure modules. Accuracy across all ranges is ±0.05%. The BetaGauge 301 utilizes temperature-compensation to ensure
accuracy in all conditions.
The Martel BetaGauge 301 features a large backlit display that can be configured to show one, two or three variables.
Another advanced feature not normally seen in this price range is the ability to easily perform pressure switch tests.
The calibrator automatically captures and displays set and reset values. Pressure readings can be displayed in a number
of engineering units including PSI, inches of water, Bar, mBar, cmH2O, kPa and others including a user defined option.
Other features of the BetaGauge 310 include remote operation via the RS-232 serial port; % Error and damping functions.
Setting up the BetaGauge 310 is simple and five frequently used setups can be stored. The last setup is automatically
recalled on power-up.
