saczel Posted December 26, 2012 Report Share Posted December 26, 2012 I have just bought a "Eutech eco testr pH2" meter and it seems like a good bit of kit. I can't believe the ease of checking compared to the 2 variable reading chemical type kits i used to use. The meter says it is at least .4 different. I checked with some old calibration fluid and the factory calibration is pretty close. This seems like it's giving me a consistent quick reading. I used to have a proper "Milwaukee" brand tester a few years back when i was into a "Hydro" phase and i could never trust it, it was all over the place. I used to think my fish where all excited because i was giving them fresh water but after testing that my tap water was pH 7 and the charcoal linear filter i put it through was 6.7 and the tank pH 7.4-7.6 i will start doing more smaller and regular changes from now on. How do people rate the cheaper ebay ones? Maybe we should do a reliability test to see how they hold up over time? Link to comment Share on other sites More sharing options...
The Tech Den Posted December 26, 2012 Report Share Posted December 26, 2012 I bought two cheapies and calibrated them the same as you do with all Ph sensor meters and when I check I use both at the same time. If I get the same read cool - if they differ - back to calibration. Link to comment Share on other sites More sharing options...
