Hi,
So I'm curious about digital readout testers such as the LaMotte ColorQ series vs the classic reagent testers like the Taylor 2006K and the new(ish) Australian brand that I was directed to from a previous post which ships to NZ, ClearChoiceLabs...
It seems on this forum that most (if not all) people prefer the classic colour testers, what's the reason for this, cost, reliability, accuracy, ease of use etc?
The digital readouts give easy to read numbers like pH 7.4 which one would hope were accurate whereas the classics require colour matching on a chart? Surely the singular digital number is easier to interpret?
I'm not colour blind (yet) that I know of and admittedly using a very basic model at the moment, Aussie Gold 4 in1, but I find it pretty hard to read it accurately along with the litmus tests due to the large range between colours on the chart. I haven't seen the Taylor or ClearChoice comparison charts in person so guessing they possibly come in smaller incremental matching between colours or I just need to refine my eye somewhat?
Ps.......Actually I did only buy the Aussie Gold 3 weeks ago and took it back today because the alkalinity was showing 160 (16 drops of solution 3 to turn clear or slightly yellow) and the litmus was showing what I determined to be approx 100ish. The pool shop SpinTouch confirmed Alk at 106 and tested the AG themselves (they sold it to me) but were at a loss to explain why it's so far out. The side of the bottle says "Lotq 02 17" which we all assumed was either the packing or manufacture date and not the expiry date.....
Excuse my ranting and drawn out ramblings...it's just how I am...but love to hear thoughts/reasons for reagents over digital.
Also I know the digital readouts use reagents, just simplifying for the discussion.
Cheers
Phil
