0.001-9999 electronic soil tester with reliable quality

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 .
