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 nitrate or nitrite using the Octa-Slide 2 Comparator. Range/sensitivity is 0.25, 0.5, 1.0, 2.0, 4.0, 6.0, 8.0, 10.0 ppm NO₃-N.

The Coliform Indicator Test Kit utilizes an easy-to-use, disposable 5-tube method to indicate the presence of Total Coliform Bacteria in a drinking water supply.

Coliform: 5 tubes, each containing a nutrient tablet, are reacted, stored at room temperature for 40-48 hours and examined for color change and gas formation.

This LaMotte Phosphate test kit tests for low range Phosphate using the LRC Comparator. Range and sensitivity is 0, 0.2, 0.4, 0.6, 0.8, 1.0, 1.5, 2.0 ppm PO₄^3–.

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

A popular, economical tool for learning the basics of water quality. No other test kit on the market compares to this portable, easy-to-use water testing kit. Students will have fun analyzing sample water for eight different test factors. This complete kit includes a manual with step-by-step, diagrammed instructions; an easy-to-use laminated color chart, and all the necessary apparatus and non-hazardous TesTabs^® to test ten water samples (three samples for coliform).

Use this kit at home or pack it into a field bag and explore the water quality of natural aquatic systems nearby. The Earth Force Low Cost Water Monitoring Kit can be used to test fresh, brackish, or saline aquatic environments.

A great learning and water testing tool for any investigator ages 8 to 98! Ideal for citizen monitoring efforts, too.

(now offered with bi-lingual instruction manuals in English and Spanish)

Macro Mania is a classroom adventure that introduces the use of stream macroinvertebrates to determine water quality. Lecture material sets the scene for the activity.

Students will learn about the influence of land use on water quality and the practice of macroinvertebrate sampling to measure water quality. Six teams will be given a deck of macroinvertebrate cards representing a sample of macroinvertebrates from one of three sites, a poster-sized sorting sheet and a map. By sorting the deck of cards onto the sorting sheets, students will determine the water quality at their site from the distribution of macroinvertebrates in their sample. Optional math, public speaking, writing, art and card game extensions will further emphasize the land use/water quality connection. Includes a deck of cards and sorting sheets for six teams. Also includes Macro Mania manual containing background information, step-by-step instructions for activities and extensions. Colorful Macro Mania classroom poster is also included!

This kit tests for Alkalinity and Hardness using the drop count method, and tests for Chlorine levels using test strips.

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).
