Frequently Asked Questions:

• Q: What is the difference between Free Chlorine (HI701) and Total Chlorine (HI711)?

  • A: Free Chlorine (HI701) measures the active chlorine available for disinfection. Total Chlorine (HI711) measures both the free chlorine and the chloramines (used chlorine). For routine pool sanitation, measuring Free Chlorine is the primary requirement.

• Q: Can I use this for drinking water?

  • A: Yes, the 0.00 to 2.50 ppm range covers the typical levels found in municipal drinking water and treated wells, making it excellent for verifying the safety of potable water.

• Q: Which reagents do I need?

  • A: The HI701 uses HI701-25 Free Chlorine powder reagents. The meter comes with a starter kit for 6 tests, but we recommend purchasing a pack of reagents to keep your testing routine uninterrupted.
