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.
