This kit tests for Total Hardness in water by using the dropper bottle method. All results are as CaCO3. Range/sensitivity is 1 drop = 10, 25, or 50 ppm CaCO3.

Direct Reading Titrator (9859X42 and X43) For determining total hardness of water Range 0 to 200 ppm as CaCO₃ in 4 ppm increments Titrators may be refilled to test higher concentrations Sufficient for 50 tests at 200 ppm Direct Reading Titrator (9859X72 and X73) For…

Applications: Industrial Water Boiling and Cooling, Water and Wastewater This kit tests for Total Hardness using the Dropper Bottle Method. All results are as CaCO₃. Range/sensitivity is 1 drop = 2, 5, or 10 ppm CaCO₃.
