Fabric Condensation Tester

Fabric Condensation Tester is for measuring condensation on textiles in a humid microclimate.

This test methods measures the water condensation accumulation on the innermost surface (back) of fabrics in a humid microclimate, with and without simulated precipitation on the outermost fabric (face) surface.

The test method measures the amount of water condensation produced in 15 minutes on a specimen placed in a humid microclimate created by controlling temperature and relative humidity of chambers on either side of the specimen. Specimens are tested with a sprinkler to simulate rain, and with no sprinkler.

The amount of water is calculated as the mass gain of a piece of pre-weighed filter paper after absorbing the condensation from the specimen.

Results are reported as g/m², where a higher valve indicates more water condensation. Area and time are constant for all specimens.

Why Choose the Fabric Condensation Tester

Choose the Fabric Condensation Tester for its precision, consistency, and intelligent control. It uses a 7-inch touch-screen interface for easy operation and offers dual testing stations for simultaneous specimen analysis. The system automatically regulates spray water temperature (8.5°C–11.5°C) and air humidity (up to 100% RH) to simulate real-world humid conditions. The built-in water temperature control and adjustable spray angle ensure accurate and repeatable testing results. With exceptional temperature accuracy (±1.0°C) and humidity precision (±4%), this tester delivers reliable data for evaluating condensation behavior on single or multi-layer fabrics. It is ideal for fabric engineers, research labs, and textile manufacturers aiming to optimize fabric performance in humid environments.
