    Keller LEO2 Ei Intrinsically Safe Digital Manometer (300bar)

    The Keller LEO2 Ei Intrinsically Safe Digital Manometer is an industrial pressure gauge that is capable of providing pressure readings from 0bar to 300bar with accuracy of ±0.1% FS and a resolution of 100mbar. The readings are taken via an internal piezoresistive pressure transducer working through a 7/16” UNF connector.

    The Keller LEO2 Ei is an intrinsically safe instrument, meaning that it is suitable for use in hazardous, combustion-prone environments. It is certified as Ex II 1G and EEx ia IIc T6 or T5 with a certification file of LCIE 01 ATEX 6001 X.

    The pressure gauge has a clear, digital screen that shows pressure readings in a number of different units. There is a min/max display option that shows the current pressure reading alongside the highest or lowest pressure measurement recorded. There is also a helpful zero function for relative measurements.

    The Keller LEO2 Ei comes supplied with an O-ring swivel seal and G 1/4” adaptor that can be used to create a strong seal on which the gauge can rotate over 360˚. A battery life of 1000 hours and IP65 rating ensure it is suitable for tricky conditions on site.
