pH Probe - Neptune Systems

  • Love this pH probe By Kyle on 12/24/13

    I have tried and used several different pH probes and this one is definitely the best. This is my 4th Neptune pH probe and I always get what I expect...............a probe that is accurate and lasts a long time. This is definitely my "go to" probe from this point forward.
  • Good Probe By Jim on 12/3/13

    Calibration fluid would have been nice to be included for initial setup. Also should be noted that there is a cap on the probe that needs to be removed prior to installation. Out of the box it reads just about dead on however.
  • Good probe, accurate 2.5 years and still going By Brian on 7/19/13

    I got this system with my Apex controller over 2-1/2 years ago. Last week was the first time it went significantly out of calibration. I soaked it in vineager for an hour to dissolve any calcium buildup and then did a long recalibration and is so far working well.

  • information needed By Bill on 5/8/13

    Easy to set up once I realized I needed a pm1 to hook it to. I think this should have been mentioned in the description. You could have sold me one. Once installed and calibrated it works great. Here again should have told me it didn't come with calibration fluid.
  • Seriously - No Calibration Fluid? By D$ on 5/1/13

    While the probe itself is awesome, I'm shocked that the calibration fluid wasn't included. I mean seriously, now I have to order the stuff ($3) and pay separate shipping - that's just stupid. Put the probe in my tank and it reads 5.21 which obviously isn't correct since nothing would be alive.
