## Questions & Answers

**Q: How many ppm of free chlorine will this read up too**
A: Range 0.00ppm - 2.50 PPM

Thank you:)

**Q: Do you have to calibrate it before every single use or does one calibaration lasts a while ?**
A: You can buy a calibration kit for this. It's cheap. It has a clear vial and a pink vial that should read 1.00 and I check it every few months to make sure its still close. Same steps as a normal residual check
 The steps for every time you check the chlorine residual include a 'calibration' to the clear water before adding the packet.
Step one turn it on, shows C-1
Step two fill the vial with water and put it in and press the button
Step three, after it says C-2, take the vial out and add the packet.
Step four put it back it after a shake and press the button. Done.

**Q: The product data pdf provided in this listing states the Hanna analysis devices are manufactuered in their new state of art  European plant.  Correct?**
A: Yes
