Some time ago there was discussion of pH meters, with a recommendation
for one sold by a Quebec firm.

I've lost the reference - can anybody help me?

As for that, probably I should ask a broader question (now that the
Canadian dollar has gained strength, and US products don't cost us 1.5
times the posted figure!) - what should I consider for a reliable pH
meter for testing my acidity?

I'm partially colour blind in red-greens, and have a real problem seeing
the end-point in reds with the TA test kits.

Thanks.

Jack.
