*WARNING:
Reagents marked with an * are considered to be potential health hazards.
To view or print a Safety Data Sheet (SDS) for these reagents go to www.lamotte.com.
Search for the four digit reagent code number listed on the reagent label, in the contents
list or in the test procedures. Omit any letter that follows or precedes the four digit code
number. For example, if the code is 4450WT-H, search 4450. To obtain a printed copy,

NOTE: The Titrator is calibrated in terms of total hardness expressed as parts
per million (ppm) calcium carbonate (CaCO
3
). Each minor division on the
Titrator scale equals 4 ppm CaCO
3
.
PROCEDURE
1. Fill the test tube (0608) to 12.9 mL line with sample water.
2. Add
fi
ve drops of *Hardness Reagent #5 (4483). Mix.
3. Add one Hardness Reagent #6 Tablet (4484A). Cap and swirl until tablet
disintegrates. Solution will turn red if hardness is present. If solution is blue
there is no measurable amount of hardness.
4. Fill the Direct Reading Titrator (0382) with Hardness Reagent #7 (4487DR).
Insert Titrator in the center hole of the test tube cap.
5. While gently swirling the titration tube, slowly press the plunger to add
Hardness Reagent #7 (4487DR) until the red color changes to blue. Read
the test result directly from the scale where the large ring on the Titrator
meets the Titrator barrel. Record as ppm Total Hardness as CaCO
3
.
EXAMPLE: Plunger tip is 3 minor divisions below line 80.
Test result is 80 plus (3 divisions x 4) equals 92 ppm.6.
