LaMotte 1985-05 SMART 3 Electronic Soil Lab Test Kit

This is a self-contained, electronic soil analysislaboratory that provides accurate answers anywhere for 15 soil factors, including available forms of macronutrients and critical micronutrients. The SMART 3 Colorimeter instantly analyzes color reactions developed in nutrient tests. Display readings are multiplied bya conversion factor specific to each test to provide a result in parts per million (ppm) or pounds per acre (lb/acre) - no further calculations are necessary. The simplified test procedures provide at least 20 tests for each soil nutrient. Each accurately standardized system isfurnished in an individual plastic module for quick distinction. All tests are performed in minutes on easy-to-prepare soil extracts, based on Mehlich I extraction. Critical soil pH measurements are performed quickly and reliably with a battery-powered digital pH meter that measures pH of a one-to-one solution of soil and distilled water over the range of 0-14 pH units to a sensitivity of ±0.01 pH. Soluble Salt levels in soils and irrigation waters are monitored accurately with a digital TDS meter measuring Dissolved Salts from 0-9999 ppm. Other parameters include Nitrate Nitrogen, Nitrite Nitrogen, Ammonia Nitrogen, Phosphorus, Potassium, Sulfur, Copper, Iron, Manganese, Zinc, Calcium, Magnesium and Chloride.
