Specifications

Milwaukee provides a range of chlorine photometers for all appli-
cations: swimming pool treatments, household cleaners, dish-
washer additives, laundry powders/liquids and cooling water
treatment products all contain chlorine as an oxidizing biocide.
Drinking water contains residual chlorine to maintain water puri-
ty throughout the supply lines.
Milwaukee offers 3 microprocessor-based instruments with
greater resolution, better accuracy and immediate results.
You can choose between three different models:
Mi404 for measuring free (0.00 to 5.00 mg/L) and total
(0.00 to 5.00 mg/L) chlorine, Mi406 for measuring free (0.00 to
5.00 mg/L) chlorine and Mi413 for measuring free (0.00 to 10.00
mg/L) and total (0.00 to 10.00 mg/L) chlorine.
Chloride is a major constituent of sea water and is extremely cor-
rosive in acidic environments. It requires close monitoring in
applications such as marine boiler systems that are effected by
seawater contamination.
Chlorides are used by the water treatment professional to deter-
mine cycles of concentration in low pressure boilers and cooling
systems.
It is essential to monitor chloride concentrations in boiler sys-
tems to prevent metal parts being damaged.
In high levels, chloride can corrode stainless steel.
