Features of Sweating Guarded Hotplate TF129

More advanced testing method

A method of hot plate method, processed with special materials, replacing the previous porous plate form, high simulation of skin sweating effect. And name sweating guarded hot plate test method too.

You can use our sweating-guarded hot plate instrument to do sweating-guarded-hot plate tests. We manufacture high-quality sweating-guarded hot plates.

More reliable test results

Equipped with an environmental chamber to ensure the most stringent control and monitoring of air temperature, air velocity, relative humidity, etc. Can do more objective testing on test samples.

A variety of automated systems make the test more intelligent and scientific.

Automatic water supply, automatic drainage system, powerful water filling system, high-precision automatic platform movement system, and input test sample thickness, the test platform can automatically rise to meet the required position. Wind speed parallels the stabilization system so that the wind speed is uniform and stable so that the test results are more stable.

Friendly and convenient test software, which can directly determine and calculate each index of the specimen.

Automatic calculation of thermal resistance, water vapor resistance (evaporation resistance), water vapor permeability index, insulation value, heat loss, and display of measurement results and dynamic curves on the computer side are available.

Wi-Fi connection for remote monitoring

Windows-based software is provided and the main unit in the test chamber is connected to the software via Wi-Fi, so the operator can control and monitor the test from the office.

Application of Sweating Guarded Hotplate TF129

What kind of textiles need thermal resistance and water-vapor resistance test?

Products with general requirements for thermal performance, such as knitted underwear, cotton garments, quilts, and various kinds of wadding as padding, etc. Some coated fabrics will require water-vapor resistance testing because the resistance of coated fabrics is generally higher than that of ordinary fabrics, which affects the comfort of wearing clothes.

Thermal resistance test and water-vapor resistance test can present the ability of fabric heat and moisture exchange, can visually express the textile warmth performance, sweaty hot, and moisture comfort performance, so useful for the enterprise for fabric selection, and product positioning.

Test Principle of Sweating Guarded Hotplate TF129

The test principle of thermal resistance is to cover the specimen on the test plate, the test plate, and its surrounding thermal protection ring, the bottom of the protection plate can maintain a constant temperature so that the heat of the test plate can only be dissipated through the specimen, air can flow parallel to the upper surface of the specimen when the test conditions achieve, determine the heat flow through the specimen to calculate the thermal resistance value of the specimen.

The test principle of water-vapor resistance is to cover the test plate with a breathable but impermeable film, and after the water enters the test plate, evaporates and passes through the film in the form of water vapor, so there is no liquid water contacting the specimen. After the specimen is placed on the film, the heat flow required to keep the test plate at a constant temperature under a certain water evaporation rate is measured, and considering the water vapor pressure through the specimen, the water-vapor resistance of the specimen is calculated.
