Brand:

Model:YN-2001

Application:

Product Introduction

I . 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 .

II . Performance Index :

1. 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 .

III . 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 ) .

5. Linear error :

≤ 3% ,(30,90,150,180μg/mL Potassium dichromate solution)

6. Power consumption : ≤ 5W (DC). 

IV . Size and Weight :

Box for pharmacy and powder :  410mm x 320mm x 180mm ; Weight : 4.7 kgs .

Box for Instrument : 410mm x 320mm x 120mm ; weight : 3.1 kgs .

VI . Testing speed :

It’s about 1 hour when testing fertilizer, hydrolyzable nitrogen, ammonium nitrogen, phosphorus and potassium ( it include time for preparing soil sample and pharmacy ) .
