Go/No-Go Roller Calibre for Capillary

Cylindrical certified calibre for checking the capillary to the Dynisco melt flow indexer. The green end of the caliper must pass through the inner diameter of the capillary but the red end of the caliber must not pass through the diameter of the capillary. If the red end of the roller gauge passes through the capillary, it means that the capillary's inner diameter does not meet the required specifications and must be replaced.
