Page 4: Introduction
Introduction Description The 7191 is a hand operated pressure pump designed to generate either vacuum to -0.95 bar (-14 psi) or pressures to 4 bar (60 psi). A high-quality screw press is designed for fine pressure adjustment, with adjusting resolution up to 0.0001 mbar (0.01 Pa). To reach the pressure stability as high as possible during the pressure calibration, an isothermal bellows chamber is designed for reducing the possible heat effects such as environmental temperature change. -
