Whether it's the single sensor BetaGauge 311 or the dual sensor BetaGauge 321, you'll have everything you need for calibrating pressure anywhere. Gas custody transfer is the ideal application for the accuracy and capabilities of the BetaGauge 321.

• 0.025% f.s. accuracy
• Two isolated, stainless steel, pressure sensors with ±0.025% f.s. accuracy (one on 311)
• 27 available pressure ranges
• Temperature-compensation ensures accuracy in field applications
• External pressure module connection supports all BETA Port-P pressure modules (29 ranges) for even more measurement capability
• Pt100 RTD input for temperature measurement, accurate to 0.01 °C
• Measures 4-20 mA input
• Internal 24 V loop power supply can power a transmitter under test
• ideal for gas flow calibration (custody transfer) applications
• Switch test on Pressure 1, Pressure 2, or external pressure module.
• Supplied with a soft carrying case, NIST Traceable Certificate, batteries and test
