At this time, the timer display will display a running time, indicating that the power is turned on. 2 Press the ON/OFF button once, and the timer will display the total time that the light box has used. 3 Press the D65 button once, the D65 lamp will light up, and the timer will display the used time of the D65 lamp. Press the F/A, TL84, CWF, U30 or UV key, the corresponding group of lamps will light up, and the timer will display the used time of the group of lamps. If you need to turn on two or more light sources at the same time, just press two or more keys at the same time. 4 Place the tested product in the middle of the bottom plate of the light box. When you need to compare the colors of two or more items, do not overlap them for viewing. They should be placed side by side in the light box for comparison. 5 The suitable observation angle is 90° light source and 45° line of sight. As shown in the figure below, the light source illuminates the object to be inspected from a vertical incident angle, and the observer observes from 45°. 6 After the test is completed, press the ON/OFF button to shut down. Turn off the power after get off work or if it is not used for a long time. 7 When replacing a new lamp, install it according to the arrangement position of the lamp or the label on the lamp holder. Do not reverse the position of different lamps. After replacing the lamp, reset the use time of the new lamp. The specific method is Turn on the replaced lamp, insert a small screwdriver into the center hole of the CLR, and press this button (the timing of other lamps that are not lit will not be cleared). Note: Do not use the CLR button when the lamp is not replaced, so as not to reset the timer time. 8 The light box is equipped with standard light sources, all of which are installed in a fixed position of the light box, and the position cannot be reversed. 9 The external power supply must have a grounding device to ensure safe use.

The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
