You would probably need a good colour detector and a PH chart that came with
the paper strips. It may then be possible to compare the desired PH colour
on the chart with that obtained from the paper test strip. I don't know if
anyone has ever done this with a colour detector but it would seem feasable.

Subject: [access-uk] Hot Tub P H meter
Hi folks, just bought a hot tub and the system relies on dipping a litmus
paper type strip in the water to check for the balance of various chemicals.
I can get my wifey to do that bit - and it sounds like a good excuse to get
out of the job, but, mug that I am, I feel that I should do it!
Has anyone found a system for doing this that is V.I. accessable?

The RNIB were demonstrating a talking security system at Sight Village this
year. Perhaps a call to Customer Services might be useful if the
information has been shared with them.
