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.
