A modification of the popular Low Cost Monitoring Kit, the Estuary Kit is specifically designed to provide simple, affordable and non-hazardous methods of testing saline and brackish waters for coliform bacteria, salinity, dissolved oxygen, nitrate, pH, phosphate, temperature, and turbidity.

Elementary Education Watershed Field Trip helps to explain the Watershed and provides guidelines on taking a field trip, conducting water quality tests, and data sheets for collection and interpretation of data.

Teacher’s manual with guidelines on taking a field trip and conducting water quality tests
Perform an actual field study
Data sheets to reproduce
Tests for pH, nitrate, phosphate, and dissolved oxygen using TesTabs^® plus temperature and turbidity
Includes all reagents and accessories and one activity from Project WET

Ideal for examining water quality in known or suspected polluted aquatic environments.

Investigate water pollution using safe, simple TesTab reagents. A lightweight, field carrying case houses 12 individual test modules. Each module contains easy-to-read, diagrammed instructions; a color chart; a test factor flashcard; and all the necessary apparatus and non-hazardous TesTabs^® to perform 100 tests. This complete, economical kit also includes a manual and The Monitor’s Handbook. Recommended for grades 5 and up.

Activities can be modified to fit specific curriculum needs or learning opportunities. Data sheets and puzzles for each unit can be printed or filled electronically by students using a computer or tablet.

MacroLens™ with 4.5X magnification fits over the entire petri dish. 4″ diameter. Available as single or in a convenient 10 pack (Order Code: 5508-10 – $177.00).

An easy-to-use, disposable tube method that indicates the presence of Total Coliform Bacteria. The water sample is placed in a tube containing a reagent tablet and incubated at room temperature for 48 hours. The tube is then examined for positive indicators of coliform bacteria such as color change and formation of gas bubbles. Each kit contains 44 capped tubes each containing a Coliform Test Tablet, and a set of laminated color chart and instruction flashcards.

Using the LaMotte Cyanide in Water Test Kit, the cyanide is first reacted with a chlorine donor to form cyanogen chloride, which then reacts with pyridine-barbituric acid to form a red-blue color. Levels are determined using the Octa-Slide 2 comparator.

This kit tests for turbidity using a turbidmetric card used match clarity to your sample. Range and sensitivity is 0, 20, 40, 60, 80, 100 JTU.

Anionic surfactants are extracted with toluene and break up an ion pair, releasing bromphenol blue into a water layer. Using the drop count method, a standard color reagent is then used to determine the concentration. Range and sensitivity is 1 drop = 1.0 ppm Detergent.
