Keller LEX1 Digital Precision Manometer (3bar)

The Keller LEX1 Digital Precision Manometer is a useful industrial pressure gauge with an oil-surrounded piezoresistive transducer that can measure absolute pressure from 0 to 2bar and relative pressure from -1 to 3bar with an accuracy of ±0.05% FS and a resolution of 0.1mbar. It takes measurements via a G ¼” male connector. It is suitable for applications including laboratory use, calibration and certain industrial uses.

The clear digital screen on the Keller LEX1 shows readings in a number of different units. It has a zero function for relative measurement and a min/max display which is easy to rest as required. Digital calibration with a zero point and end point can be used to help safeguard accuracy.

The Keller LEX1 can be connected to a recording system via the RS485 Fischer connection and an optional Keller K114A Cable Adaptor. As part of a Keller-Bus protocol – coordinated with a free CCS30 software package from the Keller website – the gauge can work with up to 127 other instruments to carry out extensive monitoring.

Two-button operation makes the Keller LEX1 very simple to use despite its complex functionality and it has an IP65 ingress protection rating. It has a 2000-hour battery life and can also be powered from an external power supply.
