The 0 to 8 bar visual indicator makes very easy to monitor the pressure state inside the circuit. It can be use on its own or can be coupled with another device. - It can be use on its own or can be coupled with another device. - on DIN rail using the relevant adaptor kit (see accessories) - With 90° bracket (see accessories) - directly on the support plate thanks to two through holes on the body Technical characteristics Fluid Filtered air.
