Stein Hall Viscosity Cup
Réf. 13745
Stein Hall Viscosity Cup
Viscosity cup for adhesives
- Viscosity Cup for adhesives
- Machined from solid Brass
- Easy to use
- Time in seconds is the Stein-Hall Viscosity
Features
La coupe de viscosité Stein-Hall pour adhésifs, détermine le nombre de secondes nécessaire à un volume défini d'adhésif pour s'écouler à travers l'orifice de la coupe de viscosité.
- Usiné à partir de laiton massif
- Forme cylindrique
- Facile à manipuler
- Facilement démontable pour le nettoyage
Procedure
The Stein hall cup must be calibrated before performing the test. Check the orifice to make sure it is not plugged, corroded or worn.
Calibration:
- Place finger over the orifice of the viscosity cup.
- Fill the cup with 75°F (24°C) water.
- Remove your finger and, with a stopwatch, measure the time it takes for the level in the cup to drop from the upper pin to the lower pin.
- The time should be 15 seconds (+/- 1 second). If it is longer than that, bend the pins together and check the calibration again. If it is shorter than that, bend the pins apart and check the calibration again. Continue until the time is 15 seconds (+/- 1 second).
General Instructions:
- Fill the viscosity cup with strained adhesive and with a stopwatch measure the time it takes for the level in the cup to drop from the upper pin to the lower pin.
- The time in seconds is the Stein-Hall viscosity.
- Record the time and temperature of adhesive.
Standards:
The instrument used throughout the industry since 1934 is called a Viscosity Cup or Stein-Hall Cup. The readings obtained do not directly correspond with any other viscosity scale.
