Programmable constant temperature and humidity test chamber advantages and methods of use
So-called programmable constant temperature and humidity chamber is a kind of intelligence mode, programmable conversion are realized in the controller. The programmable refers to the test in the process of the automated test process, for example - Set to - 20 150 and run for three hours, and then from 150 to - 20 run for three hours, and then from - 20 to 150. This cycle is to point to is programmable. Programmable refers to a kind of programmable controller, is known as a PC or PLC, is a specially designed for industrial environment application and digital electronic system operation. It USES a programmable memory storage logic operation and sequential control, timing, counting and arithmetic operation instruction, and through the digital or analog input and output interface control various types of machinery or production process. Programmability also called programmability, meaning is short for programming. It is making computer programming language code was used to solve the problem and obtain the corresponding results. Programmable constant temperature and humidity test chamber is the use of the method is as follows: 1, the first open the switch of the equipment. Equipment on the front panel controller will display the master record, the master record is divided into monitoring menu, setting an appointment set operation, curve display, set up six subdirectory program Settings and picture. 2, then, we will choose the operation setting interface. At this point, there will be two operating modes: programmable and a fixed value. Program instruction cycle running multiple temperature points, a fixed value can only be run in a temperature point. At this moment, we touch and click the button, it will turn green, this is selected. 3, the program also need to choose a good run in the run Settings, and then select a good program, in the procedures section 01 corresponding group temperature box enter the required test temperature, humidity and time, and then select the 02 corresponding procedures section of the second set of temperature box enter the required test temperature, humidity and time, and so on. 4, edit, temperature, humidity and time after operation, will use the programmable functions. First the standby temperature is set to 0. 5 degrees, select standby open, and then select the loop. 5, choose to enter the edited program, after editing the next can be directly to retrieve the title of the product under test item, and select the number of all temperature cycle need to be performed. Similarly, a part of the cycle is a cross between section number and period of cycle. Only for the start and end of the cycle set the cycle number. 6, when we need to test temperature and time, cycle number has been set, and then enter the monitor screen, choose to run the program group, into the process part, click the run button in the lower-right corner of the window, the equipment can work normally. Before we need to test all the program cycle completed, the device will not stop working. This is the so-called program operation method. The above explanation is the advantage of the programmable constant temperature and humidity test chamber, the hope can help you, if you want to learn more about programmable constant temperature and humidity test chamber of the relevant information, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!

Cut resistance is one of the most critical performance indicators in personal protective equipment (PPE) testing, directly affecting worker safety in high-risk industries such as metal processing, machinery manufacturing, and emergency rescue. The TDM Cut Test Machine GT-KC28 plays a vital role in accurately evaluating the cut resistance of PPE products, including gloves, protective clothing, footwear materials, composite materials, rubber, and industrial textiles.
By adopting high-precision force control systems, intelligent data processing, and stable transmission technology, the GT-KC28 TDM Cut Tester can accurately measure the critical cutting force of materials and ensure excellent repeatability and comparability of test results. Its user-friendly touch-screen operation, comprehensive data storage, USB data export, and built-in thermal printer greatly improve laboratory efficiency and data traceability.
The TDM Cut Test Machine GT-KC28 fully complies with major international and national standards such as ISO 13997, EN 388, ASTM F2992/F2992M, ANSI/ISEA 105, and GB 24541-2022, making it a reliable solution for PPE manufacturers, third-party testing laboratories, and research institutions. Through precise and standardized cut resistance testing, the GT-KC28 helps reduce industrial cutting injuries, supports PPE certification across global markets, and ensures that protective equipment delivers reliable safety performance in real-world applications.
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.
