I've just received my Scuba II. So far I've tested Free and Total chlorine / pH with it and the results tally with my AquaChek strips I've been using for the last few years (not the same bottle!!! )
My pool is a 6000 gallon, 26,500 Litre above ground permanent vinyl pool.
Cl - 1.8
pH - 7.0
Now I came to testing TA with it and got an odd result. I followed the instructions and got a reading of 0 (I checked twice, using 2 different sections of pool water - both were 0). My AquaChek strips said 40 (which seem more plausible). 40 seems low to me too, for those Cl / pH levels?
Does anyone know if the Scuba II can measure as low as that? What are peoples experiences of the Scuba II?
