The BetaGauge 321 Dual Sensor Pressure Calibrator provides unmatched pressure measurement flexibility over any competitive unit, setting a new standard over the venerable BetaGauge 320. The BetaGauge 321 provides 0.025% FS accuracy on both internal, isolated, stainless steel pressure sensors. An external pressure module connection supports all BetaPort-P pressure modules for even greater measurement capability. A Pt100 RTD input is provided for temperature measurements accurate to 0.1 Deg C (0.2 Deg F). In addition, the BetaGauge 321 measures 4-20 mA loop current and up to 30 VDC. An internal 24 V Loop Power Supply can power a transmitter under test.  The BetaGauge 321 supports up to  three simultaneous measurements in any combination, including three pressure measurements. With simultaneous display of two pressure and an RTD temperature measurement, the BetaGauge 321 is ideal for gas flow calibration (custody transfer) applications. The BetaGauge 321 is available in two standard configurations – 15 psi/1500 psi or 30 psi/3000 psi ranges – or customized with any two ranges selected from 5, 15, 100, 300, 500, 1000, 3000, 5000, or 10,000 psi.

The Beta 320 series is available in a Kit, which includes the BetaGauge 321 Pressure Calibrator, Pt100 RTD Probe, batteries, manual, NIST-traceable certificate, test leads, and hard-sided carrying case.
