Overview
The YONGLIDA CSB-2 Zahn Cup (Immersion) is a portable, immersion viscosity cup, model CSB-2, with an outflow aperture of 2.74mm. This product meets ASTM D4212-93 Standard Test Method for Immersion Viscosity Cups for testing the viscosity of Newtonian or near-Newtonian liquids.
Features
1. Portable immersion design, easy to operate
2. Made of stainless steel, including cup body, filter and handle
3. The accurate outflow aperture is 2.74mm
4. The cup volume is 44ml.
The correction factor range is between 0.95 and 1.05
6. Ambient Temperature Control at 25 ℃ +/- 0.2 ℃
Principle
CSB Zahn Cup calculates viscosity by measuring the time it takes for a liquid to flow out of a standard pore size. Liquids flow out of a 2.74mm pore size under standard conditions. According to the relationship between outflow time and viscosity, combined with a correction factor, an accurate viscosity value is obtained.
Applications
Newtonian liquid test, approximate Newtonian liquid test
Steps
1. Immerse the viscosity cup into the liquid to be tested
2. Ensure that the Ambient Temperature is controlled at 25 ℃ +/- 0.2 ℃
3. Record the time for the liquid to completely flow out of the outflow hole
4. Calculate viscosity values based on outflow time and correction factor
Notice
• Only suitable for Newtonian or near-Newtonian liquids
• Ensure Ambient Temperature Stable at 25 ℃ +/- 0.2 ℃ Before Use
• Regularly check whether the outflow aperture is clean and free of blockage
• The correction factor needs to be verified within the range of 0.95 to 1.05
• Avoid use in liquids beyond the viscosity range of 20~ 250cSt
