If I understand everything I have read, this would produce three things, a poor reading, hydrogen and oxygen.
I reached out to my contact at nengshi.com and the specs are wrong on the site. The probe is capable of measuring from 1-100mS/cm. I am ordering several other probes so for $15 I added in a couple of these. If they work, great. If not, maybe someday I will have a freshwater aquarium or as you say, "measure the concentration of limewater."
