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

Insta-TEST^® Chlorine Dioxide is a convenient way to test for Chlorine Dioxide levels in sanitized water. Range and sensitivity is 0, 10, 25, 50, 100, 250, 500 ppm.

This kit tests for Phosphonate using the drop count method. Range: 1 drop = 1.25 ppm HEDP, 1 drop = 1.4 ppm PBTC.

Be in control from mash to mug! The BrewLab^® Plus test kit for home brewers allows you to evaluate the quality of one of the most crucial ingredients of a successful beer—the water. Results for 8 water quality factors to allow you to calculate whether adjustments are necessary before you begin brewing. The digital pH meter provides additional information that allows you to monitor progress throughout the brewing process. A link to a popular brewing calculator is included.

Test for 8 Essential Factors

• Chloride
• Sulfate
• Alkalinity
• Total Hardness
• Calcium Hardness
• Magnesium Hardness
• Sodium
• pH

This Alkalinity test kit provides total alkalinity readings only, using a Direct Reading Titrator. Testing range/sensitivity 0-200 ppm/4 ppm as CaCO₃.

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.

This peracetic acid test kit tests for peracetic acid and hydrogen peroxide using the dropper bottle method. Range/sensitivity is 1 drop = 50 ppm peroxide and 1 drop = 15 ppm peracetic acid.

The Insta-TEST^® Low Range Chlorine test strips are a convenient way to test low range levels of Free Chlorine. Ideal for drinking water or pools. Range and sensitivity is 0, 0.5, 1, 3, 5, 10 ppm.

The test is based on the reaction of the cationic polyquat with an anionic polyelectrolyte using Toluidine Blue O as the indicator. The color change is blue to purple. Levels are determined using the drop count method. Range and Sensitivity is 1 drop = 1 ppm Polyquat.
