Sweating Guarded Hotplate TF129

4.8 (5 reviews)

Sweating Guarded Hotplate is a laboratory testing system used to test the thermal resistance properties(ability to persist a heat flow) of textiles for clothing, to make sure the end products comfortable to wear during sweating conditions, or to check the ability to protect from heat.

This type of sweating guarded hotplate is also used in testing the thermal resistance and water-vapour resistance of medical textiles like face masks and protective clothing.



Sweating Guarded Hotplate is the most professional, stable and advanced Thermal and Evaporative Resistance test instrument in the world.

Human skin simulation test plate, automatic water supply system, wind speed stabilization system, test host and climate chamber are completely separated design. Automatically adjust the height of the hotplate according to the thickness of the test sample, ensure the wind sensor is 15mm above the hotplate.

A Windows based software is offered. The main machine inside the chamber is connected with the software by Wi-Fi, so operators may control and monitor the testing in the office.

An advanced Temperature & Humidity Chamber is offered with the machine.

Note: A customized PC is needed for this instrument.
