Full Details

Conductivity probes can be used for many different functions from letting you know the salinity of a tank to the quality of RODI water. We suggest calibrating conductivity probes once every 3-6 months to keep readings reliable.


447 mS Conductivity Solution - Used for calibrating conductivity probe for freshwater applications.

  • Worked as expected. By MTWiley on 10/27/2016

    The solution worked fine for calibrating my conductivity probe. Some people have complained that it doesn't read the same as their refractometer, but you're measuring two different things. The refractometer as the name implies is looking at the refractive index of the water and using that to give you a reading. While the conductivity probe as it's name would imply looks at how conductive the water is and gives you a reading based on that.

    While we can extrapolate/infer salinity from both of those readings, they're two fundamentally different readings and will always be slightly different.

    It's also important to keep in mind that whether or not you are using temperature compensation will make a difference in accuracy for both and generally handheld refractometers don't take temperature into consideration, the Milwaukee Digital Refractometer is an exception to that though(not really a handheld refractometer).
  • Didn't work out for me. By DG on 10/18/2016

    I used the 1 pack that came with the new apex. Couldn't get it to calibrate. It read 32.

    Purchased a new packet. Still couldn't get a reliable reading after calibrating.

    Thrid time I forgo the calibration fluid. I really like they Milwaukee electronic refractometer and trust it. So I got my tank water exactly where I wanted it using the Milwaukee then calibrated the probe to my tank itself. Now it reads what I expect it to read. I likely will not try calibration fluids again. Just calibrate to match my Milwaukee.
