Soil Fertilizer Fast Testing Instrument

Soil Nutrient Fast Testing Instrument

I . Model ：YN-4001 .
II . Logo :  nanbei.
III . Instrument Components : 
1. Fast testing instrument for intelligent English display , it include instrument host, medicament, cuvette and other accessories .
2. Electronic balance , it is a weighing apparatus , precision is 0.1g , balance for precision (0.01g) is better for improving analysing precision .
