Shoe Heat Insulation Tester – Thermal Insulation Tester is used to test shoe heat insulation / thermal insulation against hot performance. Place the shoe in sandbath and the footwear shall contact with the plate(forepart and the heel) in certain temperature for a given period. Then to measure the temperature increase inside of the shoe. The contact temperature and time is specified in production standard. Sandbath Size (40±2*40±2)cm?Height?5cm Hot Plate Temperature Range RT~250°C?Accuracy ±5C?
