With the rapid development of modern industrial technology, the application fields of electrical and electronic products are becoming increasingly broad, and the environmental conditions they experience are becoming more and more complex and diverse. Only by reasonably specifying the environmental conditions of the product and correctly selecting the environmental protection measures for the product can the product be protected from damage during storage and transportation and be safe and reliable during use. Therefore, artificial simulated environment testing of electrical and electronic products is an indispensable and important link to ensure their high quality. Artificial simulated environmental tests are scientific summaries of actual environmental impacts and have the characteristics of typification, standardization, ease of use, and ease of comparison. The diversification of environmental conditions and the importance of environmental testing also put forward more stringent requirements for environmental testing equipment.
The constant temperature and humidity test chamber can be used to assess and determine the adaptability of electrical and electronic products or materials for storage and use under environmental conditions of temperature and humidity. The equipment uses air circulation to maintain the uniformity of temperature and humidity in the working room during the test. The sample is not exposed to direct radiation from the heating and cooling elements within the device.
Reference standards
This product meets the requirements of national standards such as - Test "High Temperature Test Method", - Test "Constant Humid Heat Test Method" and other related standards. - "Technical Conditions of Humidity and Heat Test Chamber" is designed and manufactured to carry out various humid and heat environment tests.
Structural design
The outer casing of the constant temperature and humidity testing equipment is made of high-quality steel plate and spray-painted. The arc-shaped design has smooth and natural lines. The inner tank is made of high-quality stainless steel plate, which can constantly control the test temperature difference ℃. The indoor sample rack and other accessories are made of stainless steel. The insulation material of the equipment pair: high-density fiberglass cotton box door is equipped with a transparent window to observe changes in indoor samples. The observation window is made of multi-layer hollow tempered glass
The humidity adopts stainless steel boiler steam humidification method with high-precision humidification cloth induction response and precise control. The mixing system uses a long-axis fan motor to make the temperature and humidity in the laboratory uniform and stable. A double-layer high-temperature-resistant high-tensile sealing strip is used between the door and the box. The test hole (on the left side of the machine) can be used for external test power cords or signal lines (the hole diameter or number of holes can be according to customer instructions). High-quality fixed movable wheels are installed at the bottom of the machine, making it easy to move the machine to a designated location and finally secure the casters.
Control system
Constant temperature and humidity test equipment generally adopts liquid crystal display programmable temperature controller imported from South Korea or temperature and humidity control instrument and temperature and humidity comparison table imported from Japan, intelligent high-precision digital display D microcomputer temperature control instrument Membrane button touch setting, digital and direct display of humidity, direct display of percentage temperature sensor uses platinum resistance tester. Temperature control adopts thermal balance temperature regulation method. The programmable temperature controller with LCD display imported from South Korea can be used for program testing. It can have multiple sets of multi-stage programming operation settings and the function of arbitrarily setting the program selection time. Temperature and humidity comparison table. The temperature directly displays the humidity. Refer to the temperature and humidity comparison table parameters to set the temperature and humidity. The main electrical components of the equipment, such as circuit breakers, AC contactors, and small relays, are all of Schneider brand, and other electrical accessories are of well-known domestic brands.
Heating and humidification system
Heating uses far-infrared nickel-chromium alloy high-speed heating electric heating wire and high-temperature completely independent system. Humidity uses stainless steel tubes with built-in nickel-chromium alloy high-speed heating electric heating wire and high-temperature magnesium oxide powder for fast response and long life. The heating and humidification systems are completely independent of humidity and have automatic water replenishment devices.
