761 LMHA
With a built-in high performance electronic pump and precision pressure controller the ADT761LA*/MA*/HA* series portable automated pressure calibrators provide for calibration of gauges, transmitters, and switches both in the field and laboratory. In a portable package, this calibrator can automatically generate pressures to 600 psi (40 bar) or 615 psia(41 bara) with 0.005% FS.
