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.
This Alkalinity Test Kit use titrations with standard acid to the phenolphthalein (P) and/or total (T) alkalinity endpoint. Range and sensitivity is 0-200 ppm/ 4 ppm as CaCO3.
The pH value affects all mineral elements and the biological processes made available to plants from the soil. Accurate pH testing is essential to determine lime requirements and to insure that a mineral-rich soil is also a fertile one.
This soil test kit tests for pH levels using the Morgan method matching test results to color charts. Range and sensitivity is pH 3.8-8.4 in 0.2 increments (not for heavy clays).
This kit tests for Chloride in fresh water samples using the Direct Reading Titrator method.
This kit tests for Silica using the Octa-Slide 2 Comparator. Range and sensitivity is 0.5, 1.0, 2.0, 3.0, 4.0, 6.0, 8.0, 10.0 ppm or 5, 10, 20, 30, 40, 60, 80, 100 ppm SiO2.
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 sample test bags for 50 students.
The Insta-TEST® 5 Way strips provide fast results for Nitrate, Nitrite, pH, Alkalinity and Total Hardness.
