Product Introduction

 Components of the Tobacco tester

1. Analyzing the nutritions in the soilsampl quickly :

TheTobacco meter, reagents, cuvettes and so on .

2. Electronic balance :

Itis a digital balance with 200g capacity, 0.1g readability. It would be betterif you choose the high accurate balance, such as 0.01g readability

3. Reagents :

Thereare more than 10 kinds of reagents (liquid or powder) provided in the Tobaccotester kit  .

4. Other accessories :

Oneelectronic calculator, one piece of filter paper, one ear suction ball, and onealuminum box.

Performance specifications:

1.  Testing items :

1.)        Iron, Boron, Calcium, Magnesium in tobacco .

2.)        Total nitrogen, total phosphorus, total potassium, copper,manganese in tobacco .

3.)        Reducing sugar, soluble sugar in tobacco .

2.  Main Technical specifications:

1.)        Power supply: DC 12V battery ;AC 220±22V  .

2.)        Testing range and Accuracy :

resolution 1μg/mL @9999μg/mL,  ;

resolution 0.Lμg/mL @ 999.9μg/mL,  ;

resolution 0.01μg/mL@ 99.99μg/mL,  ;

resolution 0.001μg/mL @9.999μg/mL,  

(1μg/mL≈1ppm≈Lmg/kg).

3.)        Stability : Drift value isless than 0.4% T(Transmittancy) or 0.3 %A( Absorbancy) , within 3 minutes afterpowering on for 20 minutes .

4.)        Sensitivity: Kλ≥3.5×10-3.(Obtained by potassium dichromate standard solution).

5.)        Repeatability : Errors is lessthan 0.4% T or 0.003 A, ( Obtained by the potassium dichromate standard solution ).

6.)        Linear error : linear error ≤±6% @Absorbance range :0.1~0.3,;linear error : ≤±4% @Absorbance : 0.3~0.6 ,; , linear error: ≤±5% @Absorbance : 0.6~0.8 ( Obtained by thepotassium dichromate standard solution ) ..

7.)        Power: ≤ 10W ( AC / DC) .

3. Size and Weight :

1.) Dimension of the reagent container : 410mm x 320mm x 180mm, weight : 4.7 Kg .

2.) Dimension of the tobacco meter container : 410mm x 320mm x120mm , weight : 3.5 Kg , including the power supply.

4. Testing time needed forone sample:

Thetesting time is needed about 1.5 hours to finish the one sample, includingmeasuring the total nitrogen, total phosphorus, total potassium, copper,manganese in soil sample or Iron, Boron, Calcium, Magnesium ,reducing sugar,andsoluble sugar contained in one tobacco sample
