    Keller LEO1 Digital Manometer (30bar)

    With a pressure measurement range of -1bar to 30bar, the Keller LEO1 Digital Manometer is well suited to a range of industrial applications. It provides readings that are accurate to ±0.1% FS and precise to 10mbar. It has a G1/4” pressure connector as standard.

    There are two measurement modes on the Keller LEO1. ‘MANO’ mode provides standard min/max measurements at a sampling rate of twice per second whilst ‘PEAK’ mode takes 5,000 measurements per second in order to capture peak or trough pressure. Both modes simultaneously display the current pressure reading alongside the user’s chosen extreme measurement.

    The Keller LEO1 has a zero function that is useful when relative measurements are required because it allows the user to cancel out any effects of barometric pressure. Measurement readings are shown in bar, mbar, hPa, kPa, MPa, PSI, or kp/cm3 on the clear digital screen and operation is carried out using just two simple buttons.

    The lightweight, compact design of the Keller LEO1 makes it easy to transport around a site and it has a battery life of up to 1000 hours in MANO mode. The IP65 casing ensures it is well protected against dust and water ingress.
