I'm not frus strated anymore now! Good luck!!
Hi.
I’ve just installed my new Profilux 4. I had some issues calibrating the conductivity probe. Second time, I’ve kept the solution bottle floating. Still the reading was still far from a RedSea refractometer. I will try for a third time the calibration. Still, the Atlas Scientific probe....it works directly with the Profilux, or you had to do some improvisation? Thanks
