A rugged field carrying case houses individual test kit modules and valuable handbooks to assist and supplement soil science studies. Each individual test module includes complete instructions and all the necessary apparatus and reagents to perform 50 tests.
Students learn preparation, extraction, and filtration techniques and procedures developed specifically for the testing of soil nutrients. Includes individual test modules for nine important soil test factors. A great supplement to the Soil Macronutrients Outfit.
Stainless steel sampler is designed for use on soft bottoms (sand or silt). A simple trigger holds the sampler open while lowering to cover a uniform area. Scissor design closes sampler, retrieving a volume of sediment to the surface for analysis.
This kit tests for Turbidity using the drop count method. Range and sensitivity is 5-100 JTU/5 JTU, 10-200 JTU/10 JTU.
Ideal for examining water quality in known or suspected polluted aquatic environments.
Twelve-inch rim dip net is fitted with a heavy canvas bag approximately 6″ deep. Bag attached to metal frame with clamp rings. Bottom of bag is a mesh material of approximately 500 micron nylon. Canvas skirt extends three inches below bag bottom to protect mesh. Aluminum pole extends from 52″ to 84″. Replacement bags available.
A simple color chart kit for measuring Copper from 0.05 to 1.0 ppm. Eight color standards are provided on the chart. Economical and easy-to-use.
In this Ammonia Nitrogen test kit, salicylate reacts to form a blue color and levels are determined using the Octa-Slide 2 Comparator. Range and sensitivity is 0.0 – 2.0 ppm NH3-N. Suitable for use in fresh, brackish and salt water.
This kit tests for Hydrogen Peroxide using the dropper bottle method. Range/Sensitivity is 1 drop = 5 ppm H2O2.
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 Topsoil Tour is an exciting classroom investigation into the physical and chemical properties of soil. Each student on the Topsoil Tour completes seven units while conducting his/her own soil tests for soil texture, pH, nitrogen, phosphorus and potassium using simple TesTabs® reagent tablets. Incorporates math and science activities.
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. Includes Instructor Manual, Student Manual with data sheets and puzzles, classroom color chart, and reagents and test tubes for 50 students.
