粘度杯是一款用于测试涂料油墨油漆等非牛顿液体粘度的检测仪器，According to应用的不同划分了不同类型的粘度杯类型，本文详细讲如何进行粘度杯选型。
南北潮According to多年的行业经验梳理了专业的选型模型供用户在购买粘度杯时方便的选择合适的粘度杯仪器。
首先先看看整体选型的维度，从粘度杯的类型、形状、杯体材质、最大粘度值、流孔直径、适用的测试标准、误差范围、是否带校准证书这些维度进行选择。
1、粘度杯类型
通常情况下，粘度杯第一个维度就是类型，确定不同类型再进一步确定其他的具体要求。粘度杯类型有：涂-4杯、Zahn杯、ISO流出杯、Ford福特杯、DIN杯、JIS岩田杯、BS流杯、AFNOR杯、FRIKMAR杯、其他。
2、粘度杯形状
由于应用场景的不同，有实验室适用也有生产现场使用，分为了手持式、台式。
3、杯体材质
不同测试样品对于测试仪器的材质某种情况下是有特别要求的，常规的是不锈钢，另外还有铝制、铜、胶木等。
4、最大粘度
NBCHAO Mall has integrated the experience of the industry, and made a division of viscosity values that are more in line with the purchase selection of users in the viscosity industry: 50cSt , 80cSt , 250cSt , 370cSt , 700cSt , 900cSt , 1200cSt , and above 1200cSt. Purchasing users can filter according to actual needs.
5. Orifice diameter
The viscosity values of different samples are different, and the outflow hole diameters of Viscosity Cups suitable for testing are different. According to the outflow hole diameters of all Viscosity Cups, the following outflow hole diameters are available: Φ1.x mm, Φ2.x mm, Φ3 . x mm, Φ4.x mm, Φ5.x mm, Φ6.x mm, Φ7.x mm, Φ8.x mm, Φ10.x mm.
6. Applicable standards
In many viscosity testing experiments, the viscosity testing is often carried out with reference to certain industry standards. Therefore, the selection of applicable standards is also an important dimension in the selection of Viscosity Cups. At present, there are still many applicable standards for Viscosity Cups, including: DIN 53211 , ISO 2431 , ASTM D4212 , ASTM D1084 , ASTM D1200 , GB/T 6753 , GB/T1723 , BS 3900 , and others.
7. Error range
The error range is the accuracy requirement for viscosity testing, which naturally divides different Viscosity Cup grades, high-grade, medium-grade, and low-grade. Common viscosity test error ranges are ±1%, ±2%, ±3%, ±4%, ±5%. In relatively strict, relatively high experimental testing requirements, and stricter product quality testing, it is natural to choose a higher precision Viscosity Cup.
8. Calibration certificate
To a certain extent, the same meaning as the error range, the instruments that have been certified and calibrated by the third party have higher reliability and guarantee in terms of product quality and measurement accuracy. However, there are still relatively few domestic Viscosity Cup brands with calibration certificates. More often, imported Viscosity Cups will have calibration certificates, such as TQC in the Netherlands.
