Martel BetaGauge 330-30 PSI Absolute

Integral Electric Pump Pressure Calibrator

The 330 is now available with a 30 PSIA (2 barA) or a 150 PSIA (10 barA) internal sensor.

Coupled with the 330’s built-in electric pump, this allows calibration down to about 20% of barometric pressure. If needed an external high vacuum source can be connected to achieve lower absolute pressures. The new ranges offer the same +/-0.025% of full scale accuracy (6 month specification) as the previously offered gauge ranges (30, 150 & 300 PSI).

Other useful features of the 330:
Built-in loop calibrator (input and output)
Large multi-variable display
24 VDC instrument power supply
Automatic pressure switch test
Available gas custody meter calibration kit
17 engineering unit displays
External pressure module compatible

For a surprisingly low cost in a surprisingly small and lightweight package, the BetaGauge 330 has a lot to offer.
