Keller LEO1 Ei Intrinsically Safe Digital Manometer (1000bar)

The Keller LEO1 Ei Intrinsically Safe Digital Manometer measures pressure up to 1000bar with a resolution of 200mbar and accuracy of ±0.1% FS. This makes it suitable for heavy-duty, industrial applications where accurate pressure measurement over a broad range is required. Measurements are taken via the gauge’s G ¼” male connector.

The intrinsically safe Keller LEO1 Ei is suitable for use in hazardous setting where there is a risk of explosion. It has an intrinsically safe classification of Ex II 1 G and EEx ia IIC T5 or T6 and the certification file is LCIE 01 ATEX 6001 X.

‘MANO’ mode on the Keller LEO1 Ei has a measurement rate of two per second and displays minimum and maximum measurements alongside the current pressure reading. The ‘PEAK’ mode, meanwhile, takes 5000 readings per second and shows a peak or trough reading alongside the current pressure reading.

The Keller LEO1 Ei has a zero function that enables relative pressure measurements, thus cancelling out variable barometric pressure. The clear digital screen shows pressure readings in multiple units and it is operated using just two buttons.

Keller part number: 303005.0010
