Keller LEX1 Digital Precision Manometer (300bar)
The Keller LEX1 Digital Precision Manometer is an advanced industrial pressure gauge that can also be used for calibration and laboratory applications. It has an absolute pressure measurement range of 0 to 300bar, accuracy of ±0.05% FS and a resolution of 10mbar. A piezoresistive pressure transducer in the oil-filled casing and a G ¼” male connector are used to take readings.
The Keller LEX1 has a clear digital screen that displays readings in a number of different units. The pressure gauge boasts a zero function and a min/max display whilst digital calibration with a zero point and an end point helps ensure accuracy.
An RS485 Fischer connection means that the Keller LEX1 can work with up to 127 other instruments as part of a Keller-Bus protocol. Free Keller CCS30 software is available to download from the Keller website and can be used to coordinate a Keller-Bus protocol. A Keller K114A cable adaptor is needed to connect the RS485 connection to a USB port.
The Keller LEX1 is operated using just two buttons and has an IP65 ingress protection rating so it is ideal for use in difficult conditions. A 2000-hour battery life adds a further level of practicality.
