HI95762-01 Free Chlorine Reagents, 100 Tests

These high quality reagents are clearly marked with the lot number and expiry date on each packet for traceability.

• Pre-made reagents for ease of use
• Prepared with high purity chemicals

The HI95762-01 are high quality reagents that are pre-measured, allowing for users to achieve fast and accurate colorimetric measurements. These reagents follow an adaptation of the Standard Method 4500-Cl G, in which the reaction between free chlorine and the DPD reagent causes a pink tint in the sample. By simply adding the HI-95762-0 reagents to the sample, the reaction will take place and Hanna’s compatible HI96762 portable meter will determine the concentration from the colour that is produced. The results will be displayed in mg/L (ppm) of free chlorine. These reagents are designed to be used with samples that have an expected range of 0.000 to 0.500 mg/L free chlorine.

Tip for an accurate measurement

• It is important that the sample does not contain any debris.
• When the cuvette is placed into the measurement cell, it must be dry outside and completely free of fingerprints, oil or dirt. Wipe it thoroughly with HI731318 or a lint-free cloth prior to insertion.
• Shaking the cuvette can generate bubbles, causing higher readings. To obtain accurate measurements, remove such bubbles by swirling or by gently tapping the cuvette.
• Do not let the reacted sample stand for too long after reagent is added, or accuracy will be lost.
• After the reading, it is important to discard the sample immediately, otherwise the glass might become permanently stained.
