Erichsen458 viscosity and temperature conversion disc

erichsen458Purpose and application of viscosity and temperature conversion disk:
#The 458 viscosity calculation chart disk is designed for viscosity measurement in different single systems. It converts viscosity measurement data in a system with a specific reference temperature.
*The viscosity calculation chart can convert viscosity data between the following units (reference temperature between 15-25 ℃)
cSt=mm2s-1
cP=mPa s
Engler degree
Krebs Stormer units
Gardner Holdt unit
Flow time
---ISO 2431 （4mm）
---ASTM D 1200(Ford No.3,No.4)
---DIN 53 211
*The viscosity scale related to temperature is used to convert viscosity data into viscosity at a specified temperature within the temperature range of 5 ℃ to 30 ℃.
erichsen458Design and function of viscosity and temperature conversion disk:

*Combine the conversion calculation diagram into a disc that can be used on both sides.
*On the viscosity calculation icon, a simple indicator reading can be used to directly compare different viscosity units. By converting the units of kinematic viscosity (cSt=mm2s-1) and dynamic viscosity (cP=mPas), the liquid density within the range of 0.7-1.5g/cm3 can be specified.
*On the viscosity scale related to temperature, when converting, directly look at the viscosity reading on the adjacent temperature scale. The use of these two calculation charts depends on the characteristics of the test liquid being close to Newtonian liquid.

Erichsen322 Immersion Viscosity Cup

richsen322Immersion viscosity cupMeasuring principle：
A substance'sviscosityExpressed as the time required for a measuring liquid of a certain capacity (usually 100 ml) to flow out completely from a cup with a specified nozzle diameter. The flow time is measured using a stopwatch.

Measurement program：
Immerse the entire cup into the substance being measured and fill it completely for measurement. Then quickly lift the cup and press the stopwatch at the same time. The time required for the substance in the cup to completely dry is measured in seconds, and the time recorded at the moment when the nozzle can be seen from top to bottom is the time of the end point. Be careful to keep the cup vertical during the testing process.

The viscosity of a substance is expressed as the time required for a certain volume of measuring liquid (usually 100 ml) to flow out completely from a cup with a specified nozzle diameter. The flow time is measured using a stopwatch.

test method：
Test steps: Immerse the entire cup into the substance being tested and fill it completely for measurement. Then quickly lift the cup and press the stopwatch at the same time. The time required for the substance in the cup to completely dry is measured in seconds, and the time recorded at the moment when the nozzle can be seen from top to bottom is the time of the end point.

ERICHSEN243 viscosity cup

ERICHSEN243Viscosity cupMeasurement principle: Calculate viscosity based on the time (in seconds) it takes for the fluid with precise volume control to flow out of the viscosity cup nozzle.
Application:
An extremely important measuring instrument for quickly and easily measuring fluid viscosity in laboratories and production.
It has high accuracy for liquids that comply with Newton's laws, suitable for low viscosity liquids, but not suitable for high viscosity substances such as pastes and pastes.
ERICHSEN243 viscosity cup design specifications:
Viscosity cupIncluding the upper cup cavity and the bottom spout. Excess fluid flows into the collection groove around the upper edge of the cavity. The general viscosity cup body is made of anodized aluminum. The nozzle is made of stainless steel. Only the inexpensive 243/I cup body is made of phenolic resin. But the spout is still made of stainless steel.
Operation Method:
*Using horizontal negotiation to adjust levels
*Place the viscosity cup on the experimental stand or in a constant temperature bath
*Close your mouth
*Fill with fluid
*Scrape a glass plate along the edge of the viscosity cup, remove excess fluid, and cover the glass plate on the viscosity cup.
*Open the spout
*Pull the glass panel horizontally and start the stopwatch at the same time.
*Stop the stopwatch and record the time when the fluid first experiences a flow interruption.
The detailed information is explained in each standard. Attention: The viscosity cup is only within the specified range and should be calibrated according to the specified time.

ERICHSEN301 viscosity gauge from Germany

GermanyERICHSEN301Viscosity rulerTesting principle:
The viscosity gauge meets Rossmann standards. Made of corrosion-resistant spring steel sheet, with two precisely sized slots, each end of which has a circular hole. This measuring device is equivalent to a capillary viscometer projected onto a plane, with grooves instead of capillaries and circular holes instead of spheres. Two grooves of different widths are equivalent to capillaries of different diameters, and the flow rate inside the grooves depends on the width of the grooves and the viscosity and density of the liquid. The relationship between the flow time using a 301 viscosity gauge and the flow time using a 4 mm DIN viscosity cup is as follows: the flow time using a DIN viscosity cup is approximately 5 times that using a narrow slot viscosity gauge, or 12 times that using a wide slot viscosity gauge.

Application:
Use Type 301Viscosity rulerThe influencing factors of surface tension are relatively low, and the end time of flow can be accurately determined. The viscosity gauge is designed to quickly determine the viscosity of paint used for spraying and brushing. On the one hand, it is a practical mixing tool when diluting paint, and on the other hand, it can be used as a device for measuring the viscosity of substances. The viscosity gauge is relatively easy to use and clean, making it a convenient instrument in practical applications.

301Performance of viscosity gauge:
Immerse the viscosity gauge into the measured liquid, completely covering the groove while keeping the circular hole at the upper end in the air. Translate into EnglishViscosity rulerQuickly lift from the liquid, keep it vertical, and measure the time until the bent liquid in the groove reaches the lower circular hole. This is clearly visible because the thin film covering the circular hole will rupture at this moment. The flow velocity in the groove will also be affected by the flow velocity of the remaining material on the ruler. So the immersion depth should be kept very precise. To obtain accurate measurement results, as an additional preparation effort, the scraper should be moistened before testing.

The flow time of paint, including volatile solvents, should not exceed 10 seconds, so measurement errors caused by solvent evaporation should be kept at the smallest possible value. The width of the groove is designed for a flow time of 5 seconds. The narrow groove is used to test spray viscosity, while the wide groove is used for brush viscosity, with corresponding markings on the groove.
