SMART 3 Electronic Soil Lab Model SCL-12

The SCL-12 soil lab 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 LaMotte Model SCL-12 is designed to provide the landowner, consultant, or fertilizer specialist with a method for achieving immediate and economical soil analyses in the field without sacrificing accuracy.

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. The simplified test procedures provide at least 20 tests for each soil nutrient.

Each accurately standardized system is furnished 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 pH 5 meter. The meter measures the 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 TDS 6 meter, measuring Dissolved Salts from 0-999+ ppm. Includes A Study of Soil Science handbook now available as a download.

Unit Conversion Factors
Results can be measured using a choice of units, explained here. Parts per million (ppm), pounds/acre, and Kg/hectare units can be converted to each other using these values:
