Constant temperature and humidity test chamber for temperature and humidity requirements
Constant temperature and humidity test chamber consists of charged with gentle humidifying two part. According to turn the cooling fan installed at the top of the box body, will complete the steam circulation system, the gas into the shell equilibrium box body temperature, environment humidity, embedded by the shell temperature, temperature sensor to collect data and information, to the temperature and humidity controller to carry out the solution, distributed temperature control desiccant-wheel based command, according to the gas heating module, the condenser pipe and stainless steel water trough in heating volatilization module to cooperate with each other. In the constant temperature and humidity test chamber during the process of humidifying indeed ascension is the vapor pressure of work, at the start of the humidifying method since the water is to the environmental test chamber wall, according to the control surface saturation pressure for the water temperature control. Box wall produce very big surface, the surface of the water in the surface to the box according to the method of spread out to the box to add water vapor pressure in the environmental test chamber air humidity increase. Because at that time the environmental humidity control is mainly with contacts with liquid silver electricity conductivity table to carry out simple switch quantity adjustment, in view of the of the big water tank temperature control weak adaptive capacity, and manipulate the whole process of cohesion is longer, do not consider variations and dampness of humidifying rules more must more key is in the box wall under the condition of flowing, inevitably there are water spray on the sample of the sample produce different levels of environmental pollution. In addition to the constant temperature and humidity test chamber drain pipe is also some rules. This way was quickly replaced steam humidification and shallow water dish humidifying. But it still has some advantages. Though its manipulation of the cohesive whole process longer, environment humidity fluctuations smaller after the system software is smooth, more suitable for stable and dampness experiment. In addition in the whole process humidifying water vapor but additional calorific value of the heat is not easy to improve the system software. Have, when the temperature of the control flow is less than the experimental point temperature, since the water spray with moisture effect. Constant temperature and humidity test chamber is able to apply to drinking water, to achieve environmental humidity effect, but if the long-term application of drinking water for water environment humidity, very easy to sprout dirt in the water pipe, residue of water adsorption to other commodities to the surface of the tank will not clean. The interpretation of the above is the constant temperature and humidity test chamber temperature and humidity requirements, hope can help you, if you want to learn more about information of constant temperature and humidity test chamber, 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.
