Summary
Ranges on the DR300 for chlorine
Answer
The DR300 for chlorine has a different procedure for each of the ranges; make sure to follow the correct procedure for the range selected. The reagent amount, sample volume, and sample cells are different between the two methods.

The high range and low range methods can be found on the website.
