Keller LEO2 Ei Intrinsically Safe Digital Manometer (31bar)

The Keller LEO2 Ei Intrinsically Safe Digital Manometer has a pressure measurement range of -1bar to 31bar, an accuracy of ±0.1% FS and a resolution of 10mbar. The pressure meter has a piezoresistive pressure transducer and a 7/16” UNF male connector.

The Keller LEO2 Ei is certified as intrinsically safe and is therefore usable in hazardous environments where there is a risk of combustion. It is classified as Ex II 1 G and EEx ia IIC T6 or T5 and the certification file is LCIE 01 ATEX 6001 X.

The digital screen on the Keller LEO2 Ei shows pressure measurements in a number of different units and it is also possible to view minimum or maximum readings alongside the current pressure reading. A zero function enables relative measurement that negates the effect of variable barometric pressure.

The Keller LEO2 Ei comes supplied with an ‘O’ ring seal swivel and a G ¼” adaptor. The IP65 ingress protection certifies that the pressure gauge is suitable for challenging environments and it also benefits from a 1000-hour battery life.
