Pressure Calibrator

The BETA 311/321 range of pressure calibrators offers the highest precision and accuracy available in a hand-held instrument. Features: two isolated, stainless steel, pressure sensors with ±0.025% FS 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; and switch test on Pressure 1, Pressure 2, or external pressure module. The instrument is supplied with a soft carrying case, NIST Traceable Certificate, batteries and test leads.
