product details

 Product introduction:

1. Micro-computer functional nutrient tester 

 Its 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. 

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 :
