Product Details

Keller LEX1 Digital Precision Manometer (1000bar)

The Keller LEX1 Digital Precision Manometer is capable of measuring pressure from 0 to 1000bar with accuracy of ±0.05% FS and a resolution of 100mbar, which makes it suitable for use in calibration facilities, laboratories and specialist industrial applications. It takes measurements with a piezoresistive transducer in oil-filled casing via a G ¼” male pressure connector.

The Keller LEX1 has a clear digital screen that can show pressure readings in a number of different units. There is a min/max recording function and a zero function that enables relative measurement. A digital calibration feature with an end point and zero point helps maintain accuracy.

An RS485 Fischer data connection allows the Keller LEX1 to act as part of a wider monitoring system. An optional Keller K114A Cable Adaptor can be used to adapt the connection to a USB port. Free Keller CCS30 software is available to download from Keller’s website and can be used to coordinate a Keller-Bus monitoring protocol with up to 128 instruments.

With just two buttons, the Keller LEX1 is surprisingly easy to operate and it also has an excellent 2000-hour battery life. The IP65 ingress protection rating certifies that it is suitable for challenging environments.
