Hanna HI3831T-050 Chlorine total DPD colorimetric method

Hanna HI3831T-050 Total Chlorine Reagent Kit – DPD Colorimetric Method (50 Tests)

The Hanna HI3831T-050 Chlorine total DPD colorimetric method is a convenient and accurate reagent kit for testing total chlorine (Cl₂) in water using the DPD colorimetric method. Total chlorine includes both free chlorine and combined chlorine (chloramines), making this kit essential for water systems where complete chlorine monitoring is required. It is ideal for use in municipal water treatment, industrial sanitation, and recreational water facilities.

Features

• Visual Color-Based Testing with DPD
  The test produces a pink color when chlorine is present. As the shade becomes more intense, the chlorine concentration increases. Thus, users can visually compare the sample to the color chart to determine precise levels.

• Measures Total Chlorine Accurately
  This kit detects both free and combined chlorine, giving users a full picture of disinfection status. As a result, it helps ensure compliance with safety standards and treatment effectiveness.

• Fast and Easy Testing Process
  Add the reagent to the sample, mix, and compare the resulting color to the included chart. In just a few minutes, you’ll have reliable data without needing electronic instruments.

• Designed for Frequent Use
  Each kit includes reagents for 50 tests, providing a practical solution for routine monitoring. Furthermore, the small size and lightweight design (only 205 g) make it ideal for field or lab use.

• Sensitive to 0.5 mg/L Increments
  With a range of 0.0 to 2.5 mg/L, and smallest increments of 0.5 mg/L, it delivers sufficient resolution for most chlorine monitoring needs.
