Product details
Application Sweating Guarded Hotplate is most advanced Thermal and Evaporative Resistance Testing instrument to simulate the heat and mass transfer processes which occur next to human skin. It accurately measures the thermal resistance (Rct) and water-vapour resistance (Ret) of fabrics, films, coatings, foams and leather including multilayer assemblies used in clothing, quilts, sleeping bags, upholstery and similar textile or textile-like products under steady-state conditions. Features: The chamber is equipped with heater, compressor, blast fan, and air flue to ensure constant temperature and humidity; The chamber adopts extra-fine glass wool to ensure good thermal insulation; Inner chamber wall made of stainless steel, flat and splendid; Integrated design of control system and water supply system, automatically keep the water supply steady without any water leakage; The height of air velocity sensor can be adjusted to ensure the air velocity sensor is always 15mm above the sample; Porous test plate to simulate human skin, easy to clean According to the thickness of the sample, the machine automatically adjusts the PID control parameters, test conditions can quickly reach. Air velocity continuously adjustable from 0 ~ 1.2m/s to meet any Thermal and Evaporative resistance testing standards. Guard ring width 127mm, to ensure that heat is passed from the test sample. LED soft lighting system. Stainless steel shell of whole machine ensures long service life; User-friendly test software; It supports various test standards, i.e. common standards & customized standards, very convenient to operate. Display the temperature of test plate, guard ring and lower guard by diagram; Connection with computer by Wi-Fi, stable data transmission and quick response. Test data can be saved as Excel format; Simple and practical design makes it convenient to analyze and print the data.
