Hello,

I was thinking of upgrading from a P3Ex to a P4 and then only the controller. This is because i bought the KHD a year ago and now the difference on looks is bothering me and when the ION is available I will buy that one to.
So to make it all look the same i have a question: Can I use the probes (PH/Temp/Cond/Redox), viewer 1, RS232 SMS module and the rest I have hooked of my P3Ex on a P4.

Thanks.

Regards,
Manuel.
