Martel BetaGauge 301 Pressure Calibrator

The BetaGauge 301 is a general purpose, valueoriented pressure calibrator. With one internal pressure range and available adapter for external BetaPort-P pressure modules, the possibilities are extensive. Available Ranges and Engineering Units. The available internal sensor ranges are: 1, 5, 30, 100 and 300 PSIG Note: 30 and 100 PSI ranges are calibrated from -12 PSI to full scale. Pressure may be displayed in the user's choice of engineering units, which include:

• PSI • Bar • mBar
• kPa • MPa • kg/cm2
• cm H2O @ 4 Deg C • cm H2O @ 20 Deg C
• cm H2O @ 60 Deg F • m H2O @ 4 Deg C
• m H2O @ 20 Deg C • m H2O @ 60 Deg F
• in H2O @ 4 Deg C • in H2O @ 20 Deg C
• in H2O @ 60 Deg F • ft H2O @ 4 Deg C
