Sweating Guarded Hotplate

Overview

Sweating guarded hotplate is the textile testing instrument for measuring of thermal and water-vapour resistance properties under steady-state conditions. By testing the thermal resistance and water-vapour resistance of textile materials, the tester provides a direct data for characterizing the textiles' physiological comfort which involve a complex combination of heat and mass transfer. The hotplate is intended to simulate the heat and mass transfer processes which occur next to human skin and measure the hence transport properties in a steady-state conditions involving combinations of temperature relative humidity, air speed, and in liquid or gaseous phase.

Standards

ISO 11092 GB/T 11048 ASTM F1868 ASTM D1518 JIS L1096

Feature

Monocoque structure is convenient for control and measurement of testing conditions.

Color touch control screen can set testing parameters and display all the real-time data.

Computer with analysis software is for displaying all the real-time data, remote control and creating test reports. It is automatic calculation for thermal resistance, water-vapour resistance (evaporative resistance), water-vapour permeability index, clo, insulation value, heat loss.

Microprocessor computer and data processor is more steady and reliable.

Automatic calibration system is more convenient to operate and provides exact testing results.
