Keller LEO1 Ei Intrinsically Safe Digital Manometer (700bar)

With a pressure measurement range of 0bar to 700bar, the Keller LEO1 Ei Intrinsically Safe Digital Manometer is capable of measuring the high pressures found in many industrial environments. It has an accuracy of ±0.1% FS and a resolution of 200mbar and takes measurements through a G ¼” male connector.

The Keller LEO1 Ei is classed as intrinsically safe for use in conditions where there is a risk of explosion such as mines and oil rigs. It has a classification of Ex II 1 G and EEx ia IIC T5 or T6 and a certification file of LCIE 01 ATEX 6001 X.

The Keller LEO1 Ei has two measurement modes. Firstly, ‘MANO’ mode takes two measurement per second and displays the minimum or maximum pressure alongside the current pressure reading. Secondly, ‘PEAK’ mode takes up to 5000 readings per second and shows trough and peak measurements with the current pressure reading.

A zero function on the Keller LEO1 Ei enables relative pressure measurement that is not affected by changes in barometric pressure. Readings are shown in multiple units on the clear digital display and the pressure gauge is operated using just two buttons.

The Keller LEO1 Ei has a battery life of 1000 hours in MANO mode and has an IP65 ingress protection rating so it is ideal for use on large sites.
