Digital manifold gauges ammonia

[Harper]

Hey!

I´m searching for digital manifold gauges the are compatible with R717.

I´ve found the CPS BlackMAX on the chillventa fair an the salesman told me that I can use the CPS also with R717. But I can´t find any specifications in the CPS documents.

Is there anybody who has experiences with digital ammonia gauges?

Thanks!
