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.
Plant tissue testing provides essential information concerning plant use of nutrients vital to their growth. These simplified field tests for green plant tissue indicate whether growing plants are receiving adequate amounts of available nutrients from the soil. All tests give qualitative results for the specific nutrients. By comparing test results from healthy and problem plants, it is possible to pinpoint deficiencies or excessive nutrient conditions.
A complete kit for determining nitrates, phosphorus and potassium in plant tissue. Diced green plant tissue is saturated in a Universal Extracting Solution to prepare a single liquid extract for use with all three tests. Qualitative results given as abundant, adequate, deficient only. Reagents for 50 tests per factor.
This copper test kit tests for copper using the LRC Comparator. Range and sensitivity is 0, 0.05, 0.10, 0.15, 0.20, 0.30, 0.40, 0.50 ppm Cu.
This kit tests for Sulfate using the Octa-Slide 2 Comparator. Range and sensitivity is 20, 40, 60, 80, 100, 120, 160, 200 ppm SO42-. Barium forms a precipitate with sulfate. The turbidity formed is measured using comparator standards or a meter.
