Calculating Chlorine residual?
Calculating Chlorine residual?
(OP)
I have a Hach tester that is not designed to read Chlorine levels above 2.20 mg/l. For Iron I can multiply the reading by the number of times I split the sample but I believe the Chlorine residual is calculated a different way when split. Your help would be appreciated.

Chlorine demand has no relation to the measurement of free chlorine residual. Sample dilution is OK as long as you compensate for the dilution, for example,with two parts chlorine fee (distilled) water and one part sample, the resultant free chlorine value multiplication factor is 3X.

The errors may be small but they are real.
