## Questions & Answers

**Q: where to get potassium chloride solution to activate orp?
is it nessery step befor caliberation?**
A: Amazon has 3M KCl and ORP standards.  I didn't activate mine with KCl and it is working just fine.  I calibrated it with a 260 MV standard.  I hope I am somewhat helpful.

**Q: How do you dispose of the calibration solution after use?**
A: Hi, the solution is non-corrosive, you can simply dispose of it normally.

**Q: can i use boiling water instead of distilled water?**
A: Boiling water is not the same as distilled water, if you capture the steam then cool it and convert it back to water then it would become distilled otherwise boiling water is very high in chlorides and tds
