I have been looking at various web sites/stores/ads, about different PH METERS, A little knowing advise would be appreciated. I Don't want too spent more than necessary too get a quality tester that will last. I have noticed that there are ones that test for chlorine and ppm( parts per million )and a few others as well..Dry Storage or WET STORAGE IN A PH 4.0 SOLUTION. HELP PLEASE
