Test Kit Hydrogen Sulfide Model HS-C Range 0-5 mg/L, Color Chart

Hydrogen Sulfide - Resulting from the anaerobic decomposition of organic matter, hydrogen sulfide is present in many water supplies.

Sewage and industrial wastes are other sources of sulfide pollution. Highly toxic, this compound has a characteristic rotten egg odor, which can be detected long before harmful concentrations are reached.

Test Kit Manganese, Model MN-5, Range 0-3 mg/L, Color Disc

Our unique color discs feature a continuous-gradient color wheel for fast, accurate comparisons. Simply rotate the color wheel to obtain a color match with the reacted sample. Typical accuracy is ± 10%, subject to individual color perception.

Test Kit Hardness Total, Model 5-B, Range 1-30 gpg, Drop Count Titration

Our economical drop count procedures provide a low-cost method for titrimetric determinations. To calculate concentration, simply add an indicator to the sample, then use the dropper to add titrant until the color changes. Typical accuracy is ± 1 drop for titrations requiring up to 20 drops and ± 5% for titrations requiring over 20 drops. Most titrations require 10 to 20 drops.
