DPD Chlorine Free PP 10ml 100/pk
DPD Free Chlorine Reagent Powder Pillows (10 mL, 100/pk) are used for rapid, accurate, and EPA-accepted measurement of free chlorine levels in water (0.02 2.00 mg/L Cl2𝐶𝑙2).
They create a colour change upon reacting with chlorine, making them ideal for monitoring sanitiser levels in pools, spas, drinking water, and wastewater using colorimeters.
Key Uses and Applications
Water Quality Testing: Primarily used in drinking water and wastewater analysis, specifically complying with Hach Method 8021 and EPA reporting standards.
Pool and Spa Maintenance: Ensures safe, hygienic swimming conditions by measuring free available chlorine, which kills pathogens.
Rapid Analysis: Convenient, pre-measured powder pillows allow for immediate, portable, and mess-free testing.
Colorimetric Detection: Used in conjunction with Hach Colorimeters or spectrophotometers for accurate colorimetric results.
Industrial Applications: Suitable for monitoring chlorine levels in various industrial water systems.

How to Use
Collect Sample: Fill a clean test vial with exactly 10ml of water.
Add Reagent: Open one powder pillow and pour the entire contents into the sample.
React: Shake or swirl to dissolve. If free chlorine is present, the sample will turn pink immediately.
Measure: For the most accurate result, place the vial in a compatible digital meter (colorimeter) to read the mg/L.
Tip: If testing water with ammonia (like chloraminated water), read the result within 1 minute to prevent interference from combined chlorine, which can cause a "false high" reading.
