This Sodium Molybdate test kit tests for molybdate using xanthate and the Octa-Slide 2 Comparator. Range/sensitivity is 1, 2, 3, 4, 5, 6, 8, 10 ppm sodium molybdate.

This kit tests for Chloride in fresh water samples using the Direct Reading Titrator method.

The Insta-TEST^® Wide Range pH test strips are a convenient way to test water for pH. Range and sensitivity is 4, 5, 6, 7, 8, 9, 10.

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.

Minute amount of color permits immediate visual distinction of different buffer values.

Measure the Total Chlorine level from 0, 1, 5, 10, 20, 50 ppm, and pH from pH 4, 5, 6, 7, 8, 9, 10 in 15 seconds. These strips are packaged with 25 strips per bottle.
