killiguy Posted October 14, 2011 Share Posted October 14, 2011 Im wondering what pH +- conductivity sensor is best and long lasting.Ive had several of those small hand held type and a larger version with separate probe and recorder box both types had only one calibrating solution 7.0.Each of these was around $70-120 but none were accurate and some way off and very quickly.All were purchased from Age Of Aquariums.As some may know I have 110 tanks and breed fish which need water from 4.0(blackwater Apistos ) to 8.0(Rift lake cichlids)and many in between(rainbows etc)Im happy to spend a couple of hundred dollars but need to to be accurate long lasting and easy to useAny suggestions?????

Elapid Posted October 14, 2011 Share Posted October 14, 2011 I also use a cheapy $10 handheld and it is accurate. Also came with 7.0 and 4.0Only problem is it can take a minute or so before it stabilizes, that could become a problem with 110 tanks!! Link to comment Share on other sites More sharing options...
