Keller LEO1 Ei Intrinsically Safe Digital Manometer (300bar)

The Keller LEO1 Ei Intrinsically Safe Digital Manometer has a pressure measurement range of 0bar to 300bar with a resolution of 100mbar and an accuracy of ±0.1% FS. It takes pressure measurements through a G ¼” male connector.

The Keller LEO1 Ei’s intrinsically safe classification is Ex II 1 G and EEx ia IIC T5 or T6 and its certification file is LCIE 01 ATEX 6001 X. This means that it is therefore suitable for use in hazardous environments where there is a risk of combustion.

In MANO mode, the Keller LEO1 Ei takes two readings per second and provides a minimum or maximum reading alongside the current pressure reading. The PEAK mode takes 5000 readings per second and allows the user to see peak and trough measurements alongside the current reading.

The zero function on the Keller LEO1 Ei allows relative measurements, thereby negating the effects of variable atmospheric pressure. The clear digital screen has a range of different units of pressure and operation – conducted through two push buttons – is extremely simple.

With a battery life of 1000 hours in MANO mode, the Keller LEO1 Ei is ideally suited to high-intensity use across multiple sites. It is small, compact, and has an ingress protection rating of IP65.
