David R Posted December 17, 2012 Report Share Posted December 17, 2012 So my trusty API pH test kit has nearly run out as I've been using it a lot since switching to rainwater for the tank, and I'm considering spending up to get something like this for the sake of both accuracy and convenience; http://www.amazon.com/Hanna-Instruments ... =hannah+ph I do have a TDS meter already but having the all-in-one unit is quite appealing. Any feedback from someone using this kinda thing would be greatly appreciated, I believe Hanna is a fairly reputable brand but certainly not the only one out there. I see there is an AquaOne electronic pH tester available, but I'm a bit sceptical of buying precision electronics from a "cheap" brand like that...

F15hguy Posted December 18, 2012 Report Share Posted December 18, 2012 http://www.getbluelab.com/shop/Bluelab+pH+Meter.html made in NZ, designed in NZ... Very high quality and 5 year garrantee. and shouldn't be too much of a price difference to that one. Quote Link to comment Share on other sites More sharing options...

Godly3vil Posted December 19, 2012 Report Share Posted December 19, 2012 But the Hanna also measure conductivity and TDS which is a big bonus. Quote Link to comment Share on other sites More sharing options...

Rabbit Posted December 19, 2012 Report Share Posted December 19, 2012 I used the below unit for years with no issue, tested against a pen probe and two liquid tests. You can perform a water change and watch the ph swing (depending how you do your water change). http://www.ebay.com/itm/Digital-pH-Meter-Water-Tester-pH-Monitor-for-Aquarium-Replaceable-BNC-probe-ATC-/400315316022?pt=LH_DefaultDomain_0&hash=item5d34a6f736 Quote Link to comment Share on other sites More sharing options...

Rabbit Posted December 19, 2012 Report Share Posted December 19, 2012 How often did you have to replace the probes and how much do they cost dude? Mine ran for 4 years straight with no probe replacement simply calibrated when it went outside the 1 degree accuracy. I was very happy with it.
