SCL-12 Smart 3 Electronic Soil Lab

The Model SCL-12 is a self-contained, electronic soil analysis laboratory that provides accurate answers anywhere for fifteen 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 by a 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.
All tests are performed in minutes on easy-to-prepare soil extracts, based on Mehlich I extraction.
