The exhibitor C. Gerhardt (A1.529) developed the N-Realyzer, a device for fully automated analysis of nitrogen caracterized by high throughput rates. The realibilty of these analysis is guaranteed by the high leak tightness of the media separated solenoid valves VYKA delivered by Festo (B2.507). In this press meeting we would like to demonstrate how the automation partner Festo could contribute to the successful development of the N-Realyzer.
