Hanna HI762-25 Free Chlorine Checker

Hanna HI762-25 Free Chlorine Reagents for HI762 Checker HC

The Hanna HI762-25 Free Chlorine Checker, pre-measured chemical packets designed for use with the HI762 Free Chlorine Ultra Low Range Checker® HC. These reagents follow the DPD colorimetric method, producing a pink coloration when chlorine is present, which the HI762 device analyzes to determine the free chlorine concentration in parts per billion (ppb).

Key Features:

• Accurate & Reliable: Formulated to provide consistent and precise free chlorine measurements in the 0 to 500 ppb range.

• Pre-Measured Convenience: Each packet contains the exact amount of reagent required, eliminating preparation errors and ensuring repeatable results.

• Fast Reaction: The color development begins immediately upon mixing with the sample, allowing for rapid chlorine detection.

• Optimized for HI762 Checker: Specifically developed to deliver best performance when used with the HI762 Ultra Low Range Chlorine Checker.

Measurement:

• Clean Cuvette Exterior: Always wipe the cuvette with a lint-free cloth (such as HI731318) to remove fingerprints, oil, or dirt before inserting it into the meter.

• Avoid Bubbles: Swirl gently or tap the cuvette to remove air bubbles that may cause artificially high readings.

• Timely Measurement: Take the reading immediately after the reagent reaction—delaying can compromise accuracy.

• Sample Cleanliness: Ensure the sample is free of debris to avoid interference.

• Proper Disposal: Discard the reacted sample immediately after use to prevent staining of the cuvette glass.

Applications:

• Drinking Water Testing

• Environmental Monitoring

• Aquarium and Aquaculture Systems

• Water Treatment Facilities
