Description
NK-4 Portable viscosity test cup/Portable coated four cups/Paint coating viscosity cup
USES:
It is suitable for measuring the viscosity of paint products in 30s-100s, and it is a portable instrument to measure the viscosity of paint, that is, the required time for the measured liquid to flow out of the hole after being filled, and the viscosity unit of the liquid is seconds.
NK-4 Portable viscosity test cup/Portable coated four cups/Paint coating viscosity cup
Main technical features:
The viscosity cup is made of brass with a capacity of about 100ml. The bottom outlet hole is made of stainless steel.
K values in the set of temperature conditions (such as 20 ℃ plus or minus 0.1 ℃) after fill in secondary standard oil viscosity cup, flow over time should be within the scope of the 30 s – 100 – s, K value should be within 0.97 1.03 K = 0.99, number 356
Specification
| Capacity | 100± 1ml |
| Inside diameter | Φ 49.5 ± 0.2 mm |
| Within the cone Angle | 81 °± 15 ‘ |
| Leakage nozzle length | 4 ± 0.02mm |

Brief description of structure:
The viscosity cup is placed on a measuring cup ring with a horizontal bubble. Adjust the horizontal screw on the base until the bubble is centered. The capacity of the cup is about 150ml.

Brief instructions:
1. Before or after measurement, clean the viscosity cup with gauze dipped in solution and dry it in the air. No residual liquid is allowed to stick to the cup or the hole of the outflow tube.
2. Before the test, adjust the horizontal screw of the base to center the blisters.
3. Mix the test solution well, and filter it in a sieve with no less than 567 holes/cm, control it at the set temperature, and keep it for 15min before measurement.
4. When the test liquid is injected into the viscosity cup, block or close the switch’s outflow hole with one finger at the same time. After filling the test liquid, scrape the liquid level at the mouth of the cup with a glass plate.
5. Release the finger or open the switch and start the stopwatch at the same time. The test liquid flows out into the line and stops the stopwatch until it is disconnected.
6. The error of the second test is no more than 0.5s.
7. Apply the first method to clean after each use.
