The Contact Coolness Tester is used to evaluate the instantaneous cool or warm sensation generated when human skin comes into contact with a material surface. You determine this sensation by measuring the peak heat flux value (qmax), which represents the maximum rate of heat transfer from the skin to the test specimen at the moment of contact.

Application

You can apply this tester to:

(1) Instantaneous cool sensation evaluation of textile fabrics.

(2) Comparative analysis of cooling performance of functional and technical textiles.

(3) Quality control and performance verification of apparel, bedding, and home textile materials.

(4) Research and development of cooling, moisture-management, and comfort-related textile products.

(5) Laboratory testing in textile research institutes and third-party testing organizations.

Standards

You can conduct tests in accordance with the following standards:

(1) JIS L 1927 — Textiles — Measurement method of cool touch feeling property.

(2) GB/T 35263-2017 — Textiles — Testing and evaluation for cool sensation at contact instant.

(3) CNS 15687 / L3272 — Method of test for the instantaneous cool sensation of fabrics.

Parameters

Features

Simulates the sensation of actual skin contact by controlling heat plate load and contact area.

Measures peak heat flux (qmax) corresponding to human thermal perception.

Supports up to 10 consecutive automatic measurements, improving repeatability and accuracy.

Built-in thermo-cool system maintains stable sample temperature while saving installation space.

Touch panel operation allows easy setup of test conditions and measurement cycles.
