By simulating the process of heat and water vapor penetrating fabrics from the human body, this device tests the thermal and moisture resistance values of various materials under stable temperature and humidity conditions. It can be used for testing the thermal and moisture resistance of fabrics, films, coatings, foams, leather, and multi-layer composite materials, such as testing the comfort performance of clothing, quilts, and thermal clothing, and testing the human comfort level of textile fabrics.

Standard Test

ISO 11092:Textiles - Physiological effects - Measurement of thermal and water-vapour resistance under steady-state conditions (sweating guarded-hotplate test)

ASTM F1868:Standard Test Method for Thermal Resistance of Clothing Using a Sweating Hot Plate

ASTM D1518:Standard Test Method for Water Vapor Transmission of Textiles

JIS L1096:Textiles - Testing methods

ISO 15831:Textiles - Physiological effects - Measurement of thermal resistance of clothing using a thermal manikin

Feature

WATER CIRCUIT wets the sample. As the sample dries, the device adds water under the porous hot plate. An insertion of a cold water can cause inaccurate results, so we heat the water in a two-stage pre-heater.

UNIFORM HEATING of the hot plate is important for accurate results: we use copper layer to achieve high uniformity. In addition, our temperature regulators measure temperature with 0.018 °C resolution.

EQUIPMENT DRAWER

The trolley includes an equipment drawer and a shelf to store all documents and small parts.

USE YOUR OWN CLIMATE CHAMBER

The device fits in all climate chambers that can accommodate 550x430x600 mm (customizable).

RUNS WINDOWS

No special computer needed. We use a Windows 10 based touch notebook computer with Ethernetand Wi-Fi: it would be easy to store the reports on your network.

The measurement application isfree, in English or Czech. We caneven do remote support!
