NB-Q3 Soil Nutrient Tester AC / DC Power For Soil NPK Fertility Fast Testing
Brief introduction of Soil nutrient tester:
Soil npk fertility is the main parameter that effect plant growth.Soil nutrient tester NB-Q3 is our perfessional design for fast testing soil npk,organic matter,pH,salinity,trace element.
It is not only to test nutrient in soil,but also can test nutrient in plant,fertility.
Features of Soil nutrient tester:
1, Microprocessor technology,digital circuit,progragmmed design,chip control,touch key,LCD display.
2, AC,DC power supply.
3, Built-in thermal printer,storage printing test result.
4, Optical filter as light source,silicon semiconductor as signal receiving system,100000hours work life.
5, Cassette adopts double-multi light path constructure design,in case of system error for different channels.
6, Automatic temperature calibration for Organic Phosphorous testing.
