BetaGauge 321A Pressure Calibrator

The BetaGauge 321A Pressure calibrator provides 0.025% FS accuracy on 2 internal, isolated,
stainless steel pressure sensors, while external connection supports all BetaPort-P pressure modules.
Accurate to 0.2°F, Pt100 RTD input is provided for temperature measurements, and product also measures
4-20 mA loop current and up to 30 Vdc.
Unit supports up to 3 simultaneous measurements in any combination.
It is available in 15 psi/1,500 psi or 30 psi/3,000 psi ranges or customized with any two ranges selected
from 5, 15, 100, 300, 500, 1000, 3000, 5000, or 10,000 psi..
