There are two versions of the Chemistry Board: the Legacy and the Professional. You can refer to the images below to see the physical differences between the two.
Functionally, both versions support pH and ORP sensing, so if you’re only installing standard chemistry probes, either board will work the same.
The Professional Chemistry Board is only required if you’re installing FlowVis Digital Flow Meters, as it’s the only version equipped with 4–20mA input ports.
To confirm what version you have, check the product packaging – look for a label that says “Professional Chemistry Board Included” on the box or on the outside of The Attendant system.
