The Keller LEO1 digital pressure gauge offers an accurate and convenient replacement to standard analog pressure gauges. Available in five standard ranges, these test gauges can display a variety of pressure units including bar, mbar, kg/cm², psi, and MPa.

A compact instrument, the LEO1 digital pressure gauge is ideally suited as a master test gauge for operation with Keller’s pneumatic or hydraulic pressure pumps, enabling simplified and efficient calibration.

The measuring element of the pressure gauge is a fully isolated piezo-resistive pressure transducer chosen for its stability, high accuracy, and reliability. The Keller LEO1 digital pressure gauge is well-suited for both static and dynamic applications and is capable of capturing transient pressure pulses with durations of only microseconds.

The Keller LEO2 is also available as a standard or intrinsically safe version, 94/9/CE. Classification: EX II 1 G EEx ia IIC T6 or T5. The EEx ia version of LEO1 Digital Pressure Gauge incorporates an additional protection switch. Functions, ranges, and accuracy are identical to the standard version.
