Soil Nutrient Analyzer 61-STI100

Soil nutrient tester with microprocessor controlled technology measures nutrient values in % and gives accurate test results. Its LCD touch display shows all test parameters, test results, which can be printed out using built-in printer. The optical filter present in the nutrient analyzer acts as light source, its silicon semiconductor acts as signal receiver system with 100000 hours of work life.
