Make friends with earthworms and discover the importance of composting! Recommended for green- and dirty-thumbs ages 8 and up.
The Insta-TEST® Nitrate / Nitrite test strips are a convenient way to quickly test water for Nitrates. Ranges and Sensitivity: Nitrate – 0, 5, 10, 25, 50 (NO3-N), Nitrite – 0, 0.5, 1, 5, 10 (NO2-N).
Ideal for examining water quality in known or suspected polluted aquatic environments.
Explore what’s coming out of your funky faucet! Test tap water for pH, chlorine, hardness, copper, and iron. Learn while you laugh with Just for Fun activities including Make Your Own Lava Lamp and edible experiments like the Pollution Parfait. Non-hazardous TesTab reagents, test tubes, word search game, internet connections and instructions for simple water quality tests also included. Perfect for sink scientists ages 8 and up.
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 pH test kit tests for pH using the Octa-Slide 2 Comparator ranging from 8.0 – 9.4 pH.
An abbreviated version of our popular Model AM-41, the new Model HP-1 offers tests for pH and three key nutrient factors: nitrogen, phosphorus and potassium. It allows the hydroponic hobbyist to maintain proper nutrient balance and to achieve optimum growing conditions in soil-less cultures. Reagents sufficient for 50 tests per factor and complete labware are foam-mounted in a sturdy carrying case. Instructions and 75-page hydroponics handbook are supplied.
This kit tests for pH using the Octa-Slide 2 Comparator. Covers a wide pH range from 3.0 – 10.5 pH.
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.
New RATIOMETRIC design in one of the most innovative, WATERPROOF, handheld meters available on the market!
The multi-detector optical configuration assures long-term stability and minimizes stray light and color interference. The new ratiometric design allows for easy and accurate testing. The nephelometric mode measures 0-50 NTU/FNU, ratiometric mode 40-1000 NTRU/FNRU and 1000-2000 AU. Now pinpoint the range of interest with better, more reliable results. Ideally suited for low-level drinking water applications, mid-range industrial applications, and high-range environmental applications.
2020t version meets US EPA design criteria as specified by EPA 180.1, Rev. 2.0 (1993) and Standard Methods 2130 B-2001.
2020i version meets design criteria for quantitative methods of turbidity using optical turbidimeters as specified by ISO 7027. Best for colored or extremely turbid samples.
Kits are supplied with 0, 1, and 10 NTU standards (Code 1974-T) or 0, 10, 100 FNU (Code 1974-I), sample bottle, six sample tubes, USB cable and wall adapter, all in a sturdy carrying case.
