Contact Coolness Tester STD-QM，JIS L 1927 contact cooling experience analyzer
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.

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.
Accessories
(1) Dual temperature-controlled heat plates.
(2) Built-in thermo-cool temperature stabilization unit.
(3) Touch panel control system.
(4) Optional PC interface and data processing software.
(5) Sample clamping and positioning components.
Test Procedures
(1) Place the specimen flat between the heat plates and ensure uniform contact.
(2) Select dry or wet test mode according to the applicable standard.
(3) Set heat plate temperature and number of measurements via the touch panel.
(4) Start the test and maintain stable ambient temperature without airflow interference.
(5) Record qmax values automatically during measurement.
(6) Export and save test data through the software after test completion.
