761 LLPD   With a built-in high performance electronic pump and precision pressure controller the 761 series portable automated pressure calibrators provide for calibration of gauges, transmitters and switches both in the field and in the laboratory. In a portable package this calibrator can automatically generate pressures from 95% vacuum to 15 psi (1 bar) with 0.02% FS accuracy.
