Specifications

Soil nutrient tester with NPK 
1.easy to operate 
2.can be measured precisely 

Detect soil, plants, chemical fertilizers, bio-fertilizers and other samples available nitrogen, available phosphorus, available potassium, total nitrogen, total phosphorus, total potassium and organic matter content.

Nutrient colorimetric simultaneously with the standard solution, the concentration of direct reading, direct look-up table that is known fertilizer, without drawing curves.

The exclusive use of fully enclosed rotating six colorimetric cassette (national patent), increased by more than six times the efficiency, avoid repeatedly adjust the instrument. Time slot zero rotation colorimetric four samples can be measured, just a few minutes.
