High and low temperature test chamber

First, the structural characteristics: 1. High and low temperature test chamber using CNC machining box, nice shape, and no reaction handle, easy to operate. 2. The inner box imported stainless steel (SUS304) mirror panels, outer box with (SUS304) brushed stainless steel or high-quality cold-rolled steel spray, increasing the appearance of texture and cleanliness. 3. There is a large observation window with bright lights to keep the box and the use of heating element embedded glass, clear observation box condition at any time. The left side of the box with a 50mm diameter test hole, for external test power line or signal line. 5. The insulation material of high density fiberglass, having a thickness of 80 ~ 100mm. With double sheets of high resistance, high temperature resistance seal between the door and the cabinet, to ensure that the seal test area. 6. with a separate limit temperature alarm system, automatically interrupt temperature exceeds the limit and run to ensure test security were not an accident. Second, the product uses: 1, high and low temperature chamber for electrical, electronics, instrumentation other products, parts and materials stored at high temperature environment, transport, and use of adaptive testing; and are all kinds of electronics, electrical, electronics, plastics and other raw materials and components were cold, heat, dry test engineering reliability and quality control testing equipment; especially suitable for fiber optic, LED, crystal, inductors, PCB, batteries, computers, mobile phones and other products high temperature, low temperature, cycle test. 2, LED special high and low temperature test chamber, Hengtai Toyoshina professional production of LED testing equipment, the equipment mainly for the LED industry, on the street, fluorescent, LED displays and other products for testing heat, cold, humidity, analog products and materials After the temperature and humidity is faulty, after alternating qualitative situation does not work, to meet the different requirements of high and low temperature. Third, the controller: 1. Using a variety of imported controller, the user can choose according to their own requirements. (1) South Korea imports TIME880 color touch screen programmable temperature and humidity control, English switch interface, easy operation. (2) imported from Korea TIME300 digital film key data input temperature and humidity control, Chinese and English display interface. (3) Japan's imports "OYO" digital touch button temperature and humidity control, PID precision control, to prevent instability in the long run. 2. Enter the data and test conditions, the controller has a locking function to avoid man-made touch and change the temperature. 3. The high and low temperature chamber controller with PID automatic calculation function, temperature conditions can be corrected immediately, so that the temperature control is more accurate and stable. The optional printer, can print the record set parameters and scan the temperature curve. 4 ~ 200mA standard signal. 5. The sensor uses a platinum resistance PT100Ω / MV. 6. With RS-232 communication interface, the computer design program, to monitor the testing process and perform other functions Switcher. Fourth, refrigeration, heating and air duct circulation system: 1. Cooling System: selection France Taikang totally enclosed (or semi-closed Germany Copeland) compressors. Air-cooled single compression / air cascade refrigeration compression mode. 2. Heating system: fully independent system, electric heating nichrome heater. 3. air duct circulation system: Multi-wing powerful air circulation blower, to avoid any dead end, the temperature distribution within the test area. Air duct return air design cycle of wind, air pressure wind speed are the test criteria, and can open the door fast instant temperature stabilization time. The electrical control system: electrical control of the main parts are imported, "Schneider" and "May Day Merlin" element, better temperature control. 5. The heating, cooling, system is completely independent can improve efficiency and reduce testing costs, increase life expectancy and lower failure rate. Temperature control output by the microcomputer calculus, to achieve high precision and high efficiency power efficiency. Five standard: high and low temperature in line with GB / T2423.1-2008, GB / T2423.2-2008 and other existing national standards. Six model specifications: 1.
