Keller LEX1 Digital Precision Manometer (31bar)
The Keller LEX1 Digital Precision Manometer has a relative pressure measurement range of -1bar to 31bar and an absolute pressure range of 0bar to 31bar with excellent accuracy of ±0.05% FS and high 1mbar resolution. Measurements are taken via the G ¼” male pressure connector and an oil-cased piezoresistive transducer. It has numerous applications in specialist industries, calibration and laboratories.
Readings are shown on the Keller LEX1’s clear digital screen in a large range of different units. The zero function enables relative measurement and the min/max function records extreme measurements. Onboard digital calibration with an end point and a zero point can be used to ensure accuracy.
The Keller LEX1’s RS485 Fischer data connector allows it to be linked up to a Keller-Bus protocol – a comprehensive monitoring system with up to 128 instruments. An optional Keller K114A cable adaptor is required to connect to a computer USB port in order to enable this feature, but free Keller CCS30 software can be used to coordinate the system.
With just two buttons, the Keller LEX1 is surprisingly easy to use despite its many functions. The ingress protection rating and 2000-hour battery life make it ideal for challenging conditions.
