Application:
Measurement of the thermal resistanceand the evaporative resistance, under steady-state Conditions, of fabrics, films,coatings, foams, and leathers, including multi-layer assemblies, for Use in clothing systems.
Qinsun Sweating Guarded Hotplateis the most professional, most advanced Thermal and Evaporative Resistance testinstrument，simulate thehuman skin test plate,Automatic water supply system, Wind speed stabilizationsystem,test unit and Climate Chamber completely separated design, Aluminumalloy shell to ensure that won't rust.
Conforms To:
ISO 11092,ASTM F 1868-09, ASTM D 1518-85, JIS L1096-2010, ASTM F 1868-02, BS8510-2009
Instrument:
Qinsun Sweating Guarded Hotplate simulates the heat process whichoccurs next to human skin. Automatic water supply system, Wind speedstabilization system, test host and Climate Chamber completely separateddesign, automatically senses the thickness of the test sample.
TestPrinciple:
Clothing isoften made of materials that impede the flow of heat and moisture from the skinto the environment. Consequently, people may suffer from heat stress or coldstress when wear in clothing in different environmental conditions. Therefore,it is important to quantify the thermal resistance and evaporative resistanceof clothing materials and to consider these properties when selecting materialsfor different clothing applications.
Features:
--- Integrated design of controlsystems and automatic water supply system, option the standard Climate Chamber.
--- Automatic water supply,Automatic drain system, Strong feed water system (In the EvaporativeResistance, water uniformly wets test plate faster)
--- High-precision automaticplatform mobile systems, enter the thickness of the test the test platform tomove to the corresponding position.
--- According to the thickness ofthe sample, the machine automatically adjust the PID control parameters, testconditions can quickly reach.
--- The patented Air velocityparallel stabilization system, let the Air velocity homogeneous and stable, sothat the test results are more stable.
--- Air velocity continuouslyadjustable from 0 ~ 1.2m / s to meet any Thermal and Evaporative resistancetesting standards.
--- Guard ring width 127mm, toensure that heat is passed from the test sample.
--- Wifi communication to PC, tomake the connection more convenient.
--- Test software to configurevariety of test standard and user-friendly.
