Keller LEO2 Ei Intrinsically Safe Digital Manometer (700bar)

The Keller LEO2 Ei Intrinsically Safe Digital Manometer has a pressure measurement range of 0bar to 700bar with accuracy of ±0.1% FS and a resolution of 200mbar. Pressure is measured through the gauge’s 7/16” UNF connector and piezoresistive pressure transducer.

As an intrinsically safe pressure meter, the Keller LEO2 Ei can be used in hazardous conditions such as those found on oil rigs, down mines and in certain types of factory. It has a classification of Ex II 1G and EEx ia IIC T6 or T5 and the certification file is LCIE 01 ATEX 6001 X.

The Keller LEO2 Ei has a digital screen that clearly displays readings in a number of different units. Min/max recording is available and the pressure gauge also has a zero function that allows relative measurement, thus negating any effects of variable barometric pressure.

The Keller LEO2 Ei is supplied with a G1/4” adaptor and an O-ring swivel seal that allows the gauge to rotate through 360˚ and maintains a seal capable of withstanding up to 300bar. A battery life of 1000 hours and IP65 ingress protection rating make it ideal for tricky conditions.
