SmartDry Dry Rate Tester is equipped with high-precision temperature sensors, wind speed sensors, precision water dripping devices, etc., which can quickly simulate the process of human sweating and quickly determine the drying rate of textiles. The specially designed parallel cross-flow fan makes the wind speed more uniform and smooth, which can restore the actual evaporation process and make the test results more reliable. SmartDry is a smart instrument, which can be connected to the SmarTexLab app installed in the smartphone through WIFI so that the parameters can be set remotely and the test process can be monitored, which greatly improves the working efficiency. SmartDry applies to the AATCC 201 standard.

A test sample is placed on top of a heating plate at a constant temperature of 37° (99°F), and a certain amount of water rises from the bottom of the instrument to the center of the plate and saturates the sample. An anemometer inside the instrument dries the sample. An infrared temperature sensor measures the change in temperature of the sample to determine if the drying is finished, then the drying speed is determined by the test drying time.
