Dear Customer,
Thank you for choosing a Hanna Product.
Please read the instructions carefully before using the
chemical test kit. It will provide you with the necessary
information for correct use of the kit.
Remove the chemical test kit from the packing material and
examine it carefully to make sure that no damage has
occurred during shipping. If there is any noticeable dam-
age, notify your Dealer or the nearest Hanna office
immediately.
Each kit is supplied with:
• HI 38000A-0 Sulfate Reagent, packets (100 pcs);
• HI 38000B-0 Sulfate Reagent, 1 bottle (53 g);
• Complexing Agent, 1 bottle with dropper (10 mL);
• 1 glass test tube (50 mL);
• 1 plastic vessel (50 mL);
• 1 plastic pipette (3 mL);
• 1 spoon.
Note:
Any damaged or defective item must be returned in
its original packing materials.
HI 38000
Sulfate
Test Kit
ISTR38000 10/99 PRINTED IN ITALY
Sulfate is largely present in natural waters in a wide range
of concentrations. It is not toxic but has to be kept below a
certain threshold to prevent it from creating an unpleasant
taste in water. The concentrations are particularly higher
close to mine run-off water. Sulfate is extensively used as a
nutrient in agriculture.
The procedure for determining sulfate is a modification of
the Barium Sulfate Turbidimetric Method.
Note:
mg/L is equivalent to ppm (parts per million).
Range
20 to 100 mg/L (ppm) as Sulfate
Smallest Increment
5 mg/L from 20 to 30 mg/L
10 mg/L from 30 to 100 mg/L
Analysis Method
Turbidimetric
Sample Size
50 mL
Number of Tests
100
Case Dimensions
275x57x78 mm (10.8x2.2x3.1")

READ THE ENTIRE INSTRUCTIONS BEFORE USING THE KIT
• Fill the plastic vessel with 50
mL of the sample, up to the
mark.
• Add 1 packet of HI 38000A-0 Sulfate Reagent and
swirl gently to dissolve.
• Add 2 drops of Complexing Agent and swirl to mix.
• Add two spoons of HI 38000B-0 reagent and swirl
gently to mix.
• Wait for 5 minutes
to allow reaction
to occur.
• Keep the test tube on a white
surface and look from the top at the
black spot on the bottom. Use the
plastic pipette to fill the tube with
the reacted sample until the black
spot has completely disappeared.

Adaptation of the Barium Sulfate Turbidimetric Method.
Sulfate is precipitated as barium sulfate by reaction with
barium chloride in acidic medium. The turbidity is propor-
tional to the concentration of sulfate:
SO
4
2-
+ Ba
2+
→
BaSO
4
• Read the concentration in mg/L (ppm) of Sulfate, in
correspondence of the level of the liquid in the test tube.
Note:
In the case the spot on the bottom disappears with
the liquid level under the 100 ppm mark , the
sulfate concentration is higher than 100 ppm; in the
case the spot disappears with the liquid level above
the 20 ppm mark, the sulfate concentration is lower
than 20 ppm.
Note:
To measure Sulfate in the 100 to 10000 ppm range,
use the
HI 38001
Sulfate Low and High Range Test
Kit.
