Re: Blue Lab Meter
Found this explanation of the 500 - 700 scales..
What's the difference between ppm500 and ppm700 scale? The ppm 700 scale is based on measuring the KCl or potassium chloride content of a solution. The ppm 500 is based on measuring the NaCl or sodium chloride content of a solution. The ppm 500 scale is also referred to as TDS - total dissolved solids.
I’ve got one and never really understood the difference in the scales. I think the 500 scale is the one to use for the most part.
