Keller LEO1 Ei Intrinsically Safe Digital Manometer (3bar)

The Keller LEO1 Ei Intrinsically Safe Digital Manometer is suitable for measuring pressure in hazardous ATEX environments. It has a pressure range of -1 to 3bar and an accuracy of ±0.1% FS alongside a resolution of 1mbar. It has a G1/4” male connector that minimises fluid loss.

The pressure meter is suitable for use in hazardous environments where there is a risk of explosion as it is certified as intrinsically safe. It is classified as Ex II 1 G and EEx ia IIC T6 or T5, with a certification file of LCIE 01 ATEX 6001 X.

The Keller LEO1 Ei has two measurement modes. The MANO mode takes two readings per second and produces the current reading alongside the minimum or maximum reading on screen. The PEAK mode takes 5000 readings per second and shows either the peak or trough reading on screen with the current pressure.

Relative measurements are facilitated by the Keller LEO1 Ei’s zero function that negates the effects of variable barometric pressure. The clear digital screen shows pressure in bar, mbar, hPa, kPa, MPa, PSI, kp/cm2 whilst operation is conducted using just two buttons.

The Keller LEO1 Ei has an IP65 ingress protection rating and a 1000-hour battery life as well as a compact, lightweight design.
