GHL Conductivity and Redox Probes Used

[ingchr1]

Probes have been used for ~22 months. The conductivity probe BNC connector is sensitive, movement of the wire at the connector causes the reading to change.

$75 shipped for both. Not looking to split. Would make good spares for someone.

Here's the charts showing when I just took them offline today.
