Selection and comparison of several desktop ISO Flow Cups
ISO outFlow Cups are mainly suitable for Newtonian or near-Newtonian fluids, with a kinematic viscosity range of 7-685mm²/s.
This article mainly compares and analyzes the selection parameters of several ISO models, namely TQC VF2051, Jingke QNB No. 6, and Kexin QNB-3. The differences between the three are shown in the following table parameters:
