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

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 Sulfite using the drop count method. Range and sensitivity is 1 drop = 5 ppm SO₃^2-.

This kit tests for Alkalinity using the dropper bottle method. Range/sensitivity is 1 drop = 10, 25, or 50 ppm as CaCO₃.

This kit tests for Carbon Dioxide where a standard alkali is used to titrate samples to the phenolphthalein endpoint. Range/sensitivity is 0-50 ppm/1.0 ppm CO_2.

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

The Insta-TEST^® Peracetic Acid test strips are a convenient way to quickly test water for peracetic acid. Range and sensitivity is 0, 10, 20, 50, 85, 160 ppm.

This kit tests for Tannin/Lignin using the Octa-Slide 2 Comparator. Range and sensitivity is 1, 2, 3, 4, 5, 6, 8, 10 ppm Tannin or lignin like substances.

This Alkalinity Test Kits uses a Direct Reading Titrator with standard acid to the phenolphthalein (P) and/or total (T) alkalinity endpoint. Range and sensitivity is 0-200 ppm as CaCO₃ in 4 ppm increments.

In this Caustic Test Kit a sample is reacted with barium to precipitate any carbonates, then is titrated with a standard acid to the phenolphthalein endpoint. Range/sensitivity is 0-10%/0.2% NaOH.
