  • Money well spent By on 3/14/2017

    Now with free shipping this is a complete no-brainer no more excuses not to calibrate pH.
  • Order more than you think you need By on 10/23/2016

    I think I have now wised up and order twice as much calibration fluid as I think I need. There is nothing worse than wondering if you probe is right and then find out you need to wait a week for a $0.99 item. Your probe is only as good as you calibrate it!
  • Simple & Easy By on 7/17/2016

    Works every time. The key to keep the temp stable while calibrating is to keep it in tank water. I simply clip it to the top of my tank submerged in water and you're off and running.

    Really 11.00 bucks shipping if this is all I need?

    I use the 7 and 10 and it works great. I pre rinse my probe in RO/DI, then start my calibration, but I will start using a little cal fluid to rinse away the water for a more accurate calibration.
