Hello,

I recently obtained a 1984 era Combo C Lector unit. It is a unit that helps determine the most favorable/visible colors based upon water visibility. It is more of a "toy" so to speak, to help learn more about color selection.

My unit is the one that has temp and pH options as well.

The manual was in rough shape, and the pages were stuck together. It looks like it got wet.

I've seen some older threads with links to download the manual, but they are older threads, and the links are no longer valid. If anyone has a copy they could share, I would greatly appreciate it.

Thanks!
