Crock Meter – Motorized

A crock meter is used to check the colour fastness of the fabric with a motorised arrangement. The instrument has an arrangement to produce the continuous rubbing on the test sample using and abrasive finger which is almost of the size of forefinger. The samples that have tendency to bleed colour will leave coloured impressions on the abrasive fingers.

The testing equipment is operated with the help of a gear motor & the arm moves in wavering motion over the specimen with a particular load and a diameter (approx. of a forefinger). The Lab testing instrument is operated with the help of a gear motor. The machine has a digital counter of 3 digits, which enables the user to set the desired number of rubs and displayed on the counter as well. As per the testing requirements or industrial requirements, the number of rubs can be pre-fed in the machine. Based on your input, the machine will start running to assess the behaviour of the fabric with respect to the number of rubs. The whole process is controlled by pressure weight that are applied on the samples during rubbing.

Presto’s Crock meter – motorised is one of the best solutions available to check the colour fastening tendency of the fabric. Apart from the fabric, it can be used on rubber to check the print fading tendency.
