Keller LEO1 Ei Intrinsically Safe Digital Manometer (31bar)

The Keller LEO1 EI Intrinsically Safe Digital Manometer is an industrial pressure meter with a pressure measurement range of -1bar to 31bar, accuracy of ±0.1% FS, and resolution of 10mbar. Measurements are taken via the G1/4” male connector.

As an intrinsically safe pressure gauge, the Keller LEO1 Ei is suitable for use in an environment where there is a danger of combustion. It has a classification of Ex II 1 G and EEx ia IIC T5 or T6 and there is a certification of LCIE 01 ATEX 6001 X.

The two measurement modes of the Keller LEO1 Ei provide flexibility for the user. The ‘MANO’ mode provides minimum or maximum pressure readings alongside the current pressure reading whilst taking readings twice per second. The ‘PEAK’ mode takes 5000 measurements per second and offers peak or trough measurements.

The Keller LEO1 Ei’s zero function allows relative measurements where variable barometric pressure is negated. Readings are shown in several different units of pressure on the clear digital screen and the operation is conducted via just two buttons.

The Keller LEO1 Ei is extremely resistant to water and dust ingress, as certified by an IP65 rating. The 1000-hour battery life makes it extremely practical for use on large sites.
