Double Junc. Ph Probes and APEX

Salty1962 · Nov 18, 2017

I saw a while back that APEX was having trouble recognizing double junction Ph probes. Does anyone know if this has been rectified?
Thx

?? a little more back ground please

I saw a post where @"Sabellafella" had posted an issue with getting the APEX to read the double junc. Ph properly. And I believe some other people had mentioned it elsewhere. I didn't know if APEX found an issue and if it's been corrected?

There is no issue with double junction probes. All Apex Systems (2016) now ship with DJ DJ will often take a bit longer to adjust (two junctions after all) to changes but this is a matter of seconds and not an issue in our application where ph values do not change rapidly.

The electrical signal from a single junction probe is exactly the same as a double junction probe, which is why they're 100% interchangeable. This wouldn't be an issue for ANY device reading the probes, not just Apex.

Got it, when I replace my probe this spring I went with the double junction with issue.
