This kit tests for Sodium using the Direct Reading Titrator method. Range and sensitivity is 0-360 ppm Na⁺

The DPD-FAS titration test kit measures Free and Total Chlorine in 0.2 ppm and 0.5 ppm increments. The distinct color change allows for accurate readings even at very low or high chlorine levels. The DipCell Color Comparator displays pH levels from 6.8 to 8.2 for 50 tests. The pH test is measured using liquid reagents.

This kit tests for Total Hardness by using the Direct Reading Titrator Method. All results are as CaCO₃. Range/sensitivity is 0-200 ppm/4ppm CaCO₃.

This kit tests for Sodium Nitrite using the Direct Reading Titrator method. Range/sensitivity is 0-1000 ppm/20 ppm NaNO₂.

The Insta-TEST^® High Range Chlorine test strips are a convenient way to test water for high range levels of Free Chlorine. Range and sensitivity is 0, 50, 100, 250, 500, 800 ppm.

This kit tests for Sulfate using the Octa-Slide 2 Comparator. Range and sensitivity is 20, 40, 60, 80, 100, 120, 160, 200 ppm SO₄^2-. Barium forms a precipitate with sulfate. The turbidity formed is measured using comparator standards or a meter.

This kit measures for acidity by using the phenolphthalein endpoint to determine hydrochloric, sulfuric, and phosphoric acids. Range/sensitivity is 1 drop = 0.1 or 1.0% (as the particular acid).

This kit tests for low ranges of Nitrite using the Dropper Bottle method. Range/sensitivity is 1 drop = 50 ppm NaNO₂.
