| Abstract: | A portable apparatus for soil and fertilizer nutrients digestion using far infrared heating is developed. In this apparatus, a single chip microprocessor technique and a pulse-width modulation mode are used, and the problem of low heating efficiency is solved excellently in the chemical digestion process.PID algorithm is adopted in the temperature-control system, thus high precision for testing the temperature is realized. Compared to the traditional digestion apparatus, this device has the following advantages: high calefaction-efficiency, small calefaction-inertia, temperature going up quickly, small dimension and light weight. |
| Keywords: | far infrared digesting-apparatus portable soil nutrient |
