it carefully to make sure that no damage has occurred

during shipping. If there is any noticeable damage, notify

your Dealer or the nearest Hanna office immediately.

Each kit is supplied with:

• HI 38015A-0 Chloride Reagent, 1 bottle (100 mL);

• HI 38015B-0 Chloride Reagent, 2 bottles with drop-

per (2x25 mL);

• HI 38015C-0 Chloride Reagent, 1 bottle (100 mL);

• Demineralizer Bottle with filter cap for about 12 liters

of deionized water (depending on the hardness level

of water to be treated);

• 1 calibrated plastic vessel (50 mL) with cap;

• 1 plastic pipette (3 mL);

• 1 plastic pipette (1 mL);

Chloride ions are one of the major inorganic anions in water

and wastewater. Although high concentrations of chloride in

water are not known to be toxic to humans, its regulation

is mainly due to adverse effect on taste. It is essential to

monitor chloride concentration in boiler systems to prevent

metal parts being damaged. In high levels, chloride can

corrode stainless steel and be toxic to plant life.

The Hanna Test Kit is equipped with all you need to

determine chloride level of water. The kit is quick and easy

to use.
Note: mg/L is equivalent to ppm (parts per million).

SIGNIFICANCE AND USE

CHEMICAL REACTION

The chloride level in mg/L (ppm) is determined by a silver

nitrate titration, using potassium chromate as indicator.

The color change from yellow to brick-red determines the

end point of this titration.

INSTRUCTIONS

READ ALL THE INSTRUCTIONS BEFORE USING THE TEST KIT
Note: Label the two syringes to avoid cross-contamination

as follows:
tag the syringe to be used for sample extraction as

"S" and "T" the other for titration (HI 38015C-0).

High Range - 5000 to 100000 mg/L of Chloride

1- To measure chloride in the 5000 to

100000 mg/L range, rinse and fill

the S (sample) syringe with water

sample. Remove the cap from the

plastic vessel and add 0.25 mL of

sample.

Note: To measure exactly 0.25 mL of

sample with the syringe, push

the plunger completely into the

syringe and insert the tip into

sample. Pull the plunger out until

the lower edge of the seal is on

0.0 mL mark of the syringe. In-

sert the syringe into the vessel

and push the sample out until

the lower edge of the seal is on

the 0.25 mL mark (the longer

mark between 0.2 and 0.3).

2- Remove the cap and

fill the Demineralizer

Bottle with tap wa-

ter.

3- Replace the cap

and shake gently for

at least 2 minutes.

The demineralized

water is now ready.

4- Flip open the top of the Demineralizer Bottle cap. By

gently squeezing the bottle, add demineralized water

to the vessel up to the 25 mL mark. Replace the cap

and swirl to mix.

Range Test Kit

5- Using the 1 mL plastic pipette, add to the vessel 1 mL

of HI 38015A-0 reagent. Replace the cap and swirl the

vessel in tight circles to mix.

6- While swirling the vessel, add

10 drops of HI 38015B-0 re-

agent through the cap port.

The solution will become a yel-

low color.

7- Take the titration syringe (T la-

beled), and push the plunger

completely into the syringe. In-

sert tip into HI 38015C-0 solution

and pull the plunger out until

the lower edge of the plunger

seal is on the 0 mL mark of the

syringe.

Caution: Avoid skin and eyes contact

with HI 38015C-0 reagent. It may

cause irritation to eyes and dark

spots on skin for some time.

8- Place the syringe into the cap of the

plastic vessel and slowly add the titra-

tion solution one drop at a time.

Swirling to mix after each drop. Con-

tinue adding titration solution until

the solution in the plastic vessel changes

from yellow to brick-red.
