Hi TJ. Yes, that is the measure.
0.754 mmhos/cm X 1,000 = 754 umhos/cm
millimhos to micromhos
umhos/cm is the same as uS/cm (microSiemens/cm)
Now, if this is correct, you're way lower on conductivity than Dr. Bruce. Electrofishing works very well in water with this conductivity.
If you thought that your water was more mineralized than this, maybe I should send down the pen, and let you take another reading?
