Manual Crockmeter for Colour Fastness to Rubbing Testing

A Manual Crockmeter is a hand-operated testing instrument used to check a fabric’s colour fastness to rubbing — whether dye transfers from the material when it’s rubbed against another surface under dry or wet conditions. Amith Garment Services offers this crockmeter for testing fabrics, yarns, and garments in compliance with ISO, European, and AATCC standards.

Unlike motorized units, the manual crockmeter is operated by hand, making it a straightforward, low-maintenance choice for labs that run occasional tests or prefer equipment with no electrical components to service. Its chrome-plated mild steel construction is built for durability, and interchangeable finger attachments (16mm for apparel fabrics, 25mm for furnishings) allow it to handle a range of fabric categories. An optional yarn-testing attachment extends its use to colour fastness testing on yarn samples.

Textile mills, small and mid-sized garment manufacturers, universities, and fabric testing centres favour this instrument for its simplicity, portability, and lower upfront cost compared to digital alternatives, while still meeting the same rub-fastness standards required for buyer compliance and export approval.

Amith Garment Services has served the Indian textile industry since 1999, backing every manual crockmeter with an NPL/NABL-traceable calibration certificate, warranty, and detailed user manual.

Frequently Asked Questions:

What is a Manual Crockmeter used for?

A Manual Crockmeter is used to test a fabric's colour fastness to rubbing by moving a test specimen against a standard white cloth under controlled pressure. It evaluates dye transfer during both dry and wet rubbing, helping textile mills, garment manufacturers, and testing laboratories ensure colour stability before production or export.

Is a Manual Crockmeter as accurate as a Digital Crockmeter?

Yes. Both Manual and Digital Crockmeters follow the same ISO and AATCC testing standards for rubbing finger size, traverse length, and applied force. When operated correctly, both provide reliable and accurate results. The main difference is that the digital model automates the rubbing motion for improved consistency and convenience.

Which industries use a Manual Crockmeter for testing?

Manual Crockmeters are widely used in textile mills, garment manufacturing units, fabric testing laboratories, universities, research institutes, and quality control departments. They are particularly suitable for laboratories performing periodic colour fastness testing without requiring motorized equipment.

What is a Manual Crockmeter?

A Manual Crockmeter is a hand-operated textile testing instrument that measures a fabric's colour fastness to rubbing. It determines whether dye transfers from the test material onto a standard white cloth during controlled friction, helping verify product quality.

How does a Manual Crockmeter work?

The operator manually moves a rubbing finger fitted with a standard white test cloth back and forth across the fabric sample under controlled pressure. After the test, the amount of colour transferred is compared with a grey scale to determine the rubbing fastness rating.

Why should I choose a Manual Crockmeter over a Digital Crockmeter?

A Manual Crockmeter is an excellent choice for laboratories that perform occasional testing or prefer a cost-effective, low-maintenance solution. It offers the same ISO and AATCC-compliant testing accuracy as a digital model while operating without electricity, making it economical and easy to use.
