It measures in mS, which can closely approximate the ppm of the ionic portion of EIS (Trem gives a factor of 1.2:1 for freshly made EIS, and 1:1 for ages EIS). As I said, it is not the best, but the easiest and cheapest. I use both that and a spectrophotometer, one is fast and easy, the second more of a hassle, more expensive, but much more accurate.
