  • The 7191 is a hand operated pressure pump designed to generate either vacuum to -0.95 bar (-14psi) or pressures to 4bar (60psi). A high-quality screw press is designed for fine pressure adjustment, with adjusting resolution up to 0.0001mbar (0.01Pa). 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. The 7191 is designed without a non-returning valve meaning minimal maintenance is required. Two finger-tight connectors installed on the pump allow the user using fingers to connect and disconnect the reference gauge and devices under test quickly and easily without the need for PTFE tape or wrenches.

    The 7191 is ideal for applications requiring accurate low pressure testing and calibration. It can be used in calibrating low pressure gauges, transmitters, or other pressure measuring instruments. Also available is the 7190 micro pressure calibration pump that provides an excellent solution to precision pressure generation between -400mbar to 400mbar.

    To accompany the pump a wide range of digital pressure gauges are available. The TEG-CV4b covers the full range of the pump (-1 to 4bar) with accuracies of either 0.2%, 0.1%, 0.05%, or 0.025% of full scale.
