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 .
    3. Medicaments , we can supply more than 20 kinds of finished medicament and powder for testing .
    4. Others , it include electronic calculator , filtering paper , ear wash ball , aluminum box , etc . It can work well out of Lab and portable to carry .
