Dual Range Chlorine Test Kit, DPD | LaMotte 3314-01

This Dual Range Chlorine Test Kit tests for high and low ranges of chlorine using the Octa-Slide 2 Comparator. Low range: 0.1-1.0 ppm Cl. High range: 1.0-6.0 ppm Cl.

Test kit includes:

• Chlorine DPD #1R Tablets (100)
• Chlorine DPD #3R Tablets (100)
• Test Tubes 2.5-5.0-10.0 mL plastic w/caps (2)
• Octa-Slide Viewer
• Chlorine Octa-Slide Bar 0.1-1.0 ppm
• Chlorine Octa-Slide Bar 1.0-6.0 ppm

Free, combined, and total chlorine may be determined using DPD with either colorimetric or titrimetric methods. These determinations are generally limited to concentrations of 0-10 ppm, although the FAS titration can test higher concentrations with the addition of more DPD indicator. Higher concentrations require the iodometric titration, whereby the sample is acidified and iodide is added, which is oxidized by chlorine to iodine and is titrated with a standard thiosulfate solution.
