N /P/K soil instrument used for testing soil nutrient  

Model : YN-2001

Instrument Components :

1. Micro-computer functional nutrient tester

It’s a main component , including host instrument,filter,color plate , and so on .

2. Glassware :

Volumetric flasks, scale straw, triangle flasks, funnel, distillation tube, absorption bottle, and so on .

3. Tray Balance :

It is a weighing instrument , inductance is 0.1g . Better if you can use balance with inductance for 0.01g , it can improve testing accuracy .

4. Pharmacy and powder :

More than 20 kinds of liquid pharmacy and powder , it can analyze more than 100 soil samples . all pharmacy is enough and available except for distilled water and ethanol when testing samples .

5. Others : Calculator, Filter paper, washing ear ball, aluminum box , it can finish test without any laboratory equipments .

Performance Index :

Testing items :

1.) Hydrolytic nitrogen,ammonium nitrogen,nitrate nitrogen,available phosphorus,available potassium,organic matter,PH in the soil .

2) N, P, K fertilizer and urea,ammonium nitrogen,nitrate nitrogen,available phosphorus,available potassium in complex ( mixed ) fertilizer .

3.) Nitrate nitrogen, phosphorus and potassium in plants .

4.) Others : Middle,trace elements Ca,Mg,Cu,Fe,Mn,B,Cl,S and so on .

Technical Index :

1. Power : 220V±22V for AC ; 12V for Battery ( DC ) .

2. Measuring range and Resolution (0.001 – 9999 ) :

       9999μg /mL,   resolution 1μg/mL (1μg/mL≈1ppm≈Lmg/kg) ;

       999.9μg/mL,   resolution 0.Lμg/mL (1μg/mL≈1ppm≈Lmg/kg) ;

       99.99μg/mL,   resolution 0.01μg/mL (1μg/mL≈1ppm≈Lmg/kg) ;

       9.999μg/mL,   resolution 0.001μg/mL (1μg/mL≈1ppm≈Lmg/kg) .

3. Stability : Displayed drift number is less than 0.5 % (A) , (transmittance measurement) within 3 minutes after powering on for 20 minutes .

4. Repeatability error : Error is less than 0.4% (A) ( testing in potassium dichromate standard solution, 2000μg /mL ) . ( transmittance testing ) .
