The Martel BetaGauge 330 pressure calibrator is a small, lightweight hand held calibrator that generates pressures up to 150 PSI using a high performance integral electric pump or 300 PSI with a manual pump. The BetaGauge 330 provides ±0.025% of full scale accuracy on its internal, isolated pressure sensor. It also features temperature compensation on its internal sensor, which ensures accuracy in field applications and an external pressure module connection that supports all 29 ranges of BetaPort-P pressure modules for even greater measurement capability

Other features of the Martel BetaGauge 330 pressure calibrator include switch test, which can be performed on internal or external pressure input, percent (%) error and damping functions, and up to five frequently used setups which can be stored and retrieved with one button recall. The compact, rugged design operates on eight (8) standard AA Alkaline batteries. Due to the power saving design incorporated in the BetaGauge 330, it can perform approximately 300 calibration cycles on one set of batteries.

The BetaGauge 330 comes in ranges of -12 to 30 PSI (gauge or absolute), -12 to 150 PSI (gauge or absolute) and -12 to 300 PSI (gauge only). The 300 PSI version uses a manually operated handpump.
