Lamotte 3643-SC SMART Reagent System

The Lamotte 3643-SC SMART Reagent System is a colorimeter reagent set for measuring chlorine, bromine and iodine levels. It covers free chlorine from 0 to 4 ppm, total chlorine from 0 to 4 ppm, bromine from 0 to 9 ppm and iodine from 0 to 14 ppm. The product is supplied new and is graded for laboratory use. It suits technicians who need a single reagent pack for multiple halogen tests.

Compatibility check before ordering

Verify that your colorimeter accepts Lamotte SMART reagent cartridges before purchase. Confirm the instrument can read the stated concentration ranges for free chlorine, total chlorine, bromine and iodine. Ensure you have the correct test protocol for each parameter you intend to measure. No additional hardware or software requirements are listed in the specifications.

Thermals, noise and power in use

The reagent system itself generates no heat, noise or electrical draw during testing. Power consumption and thermal output depend entirely on the colorimeter you use with it. Store the reagents at stable room temperature to maintain chemical integrity. The manufacturer notes no special shelf-life restrictions for this product.

Questions about this item

Does the Lamotte 3643-SC SMART reagent system include the colorimeter itself or only the reagent chemicals?

This product supplies the reagent chemicals for chlorine, bromine and iodine testing; the colorimeter instrument is a separate purchase.

Which measurement ranges does the 3643-SC reagent set cover for each analyte?

The reagents support 0-4 ppm free chlorine, 0-4 ppm total chlorine, 0-9 ppm bromine and 0-14 ppm iodine.

What does the 0-4 ppm chlorine range mean when I run a test on my water sample?

The reagent reacts with chlorine in the sample so the colorimeter can display a concentration between zero and four parts per million.
