Ventilated Sweating Guarded Hotplate

Patent No. 200610154833.9

This apparatus is designed to test fabrics thermal resistance and humidity resistance under certain conditions.

The machine’s testing accuracy is much higher than referenced standards call for, therefore, it’s an ideal piece of equipment to conduct fabric performance testing.
