Keller LEO1 Digital Manometer (3bar)

The Keller LEO1 Digital Manometer has a pressure measurement range of -1bar to 3bar with accuracy of ±0.1% FS and a resolution of 1mbar. This makes it suitable for a range of industrial applications where very accurate and precise pressure measurement is required. Pressure readings are taken via the G ¼” pressure connection that is suitable for hoseless connection, thus minimising fluid loss.

The Keller LEO1 has two measurement modes depending on the application. Firstly, ‘MANO’ mode takes a reading twice every second and shows the current pressure alongside the minimum or maximum pressure since the ‘RESET’ button was last pressed. ‘PEAK’ mode, meanwhile, takes readings 5,000 times per second and shows the actual pressure and the peak or trough pressure recorded.

A zero function is very useful for negating atmospheric conditions and taking relative measurements. The Keller LEO1 displays pressure in a number of different units (bar, mbar, hPa, kPa, MPa, PSI, kp/cm3) and is operated using just two buttons, making it very easy to use.

The Keller LEO1 weighs just 210g and is very compact and durable, with an IP65 ingress protection rating. It has a battery life of 1000 hours (in ‘MANO’ mode) and operates from a CR2430 3V battery.
