constant temperature & humidity test chamber

Product Name:XPS-225T constent temperature & humidity test chamber Model: XPS-225T Product Description: Instrument Description: Usage: This series of products for the aerospace products, information, electronic instruments, materials, electric, electronic products, electric strength of high temperature or humidity conditions in the environment, test its performance. Standard: GB/T2423.1-2001 GB/T2423.2-2001 GB/T2423.3-1993 ....... Technical parameters: Model: XPS-225T Temperature range: -20 °C 150 °C Humidity range: 20% 98% RH Temperature uniformity: ± 1 °C Humidity Uniformity: ± 3% Temperature accuracy: ± 0.5 °C Humidity Accuracy: ± 2.5% RH Heating time: -20 °C 100 °C in about 35 minutes Cooling time: 20 °C -20 °C in about40 minutes Inner box size (cm) W50 H75 D60 Carton size (cm) W102 H185 D107 Structure Material: Inner tank: SUS # 304 stainless steel mirror Carton: SUS # 304 stainless steel, fine spray Refrigeration systems: single-stage air-cooled compressor Europe and the United States and imported closed, green open type refrigerant HC Heated humidification system: Heating: Stainless steel heating tube humidification mode chip Humidity: stainless steel electric heating vapor form Safety protection device: compressor overheating, over-fond of overpressure, heat, wet and dry, box-temperature, water tank alarm system Standard accessories: View window, test hole 50 × 1 only, 2 sets of sample rack, 1 set of lights Power (KW):6.5 Power: 22VAC ± 10% / 3P80VCA ± 10% Main features: Case structure: Ø 1, box shape using CNC machining and elegant and no-reaction handle, easy to use. Ø 2, box of imported high grade stainless steel liner (SUS304) mirror panel box outside the gallbladder with A3 steel spray, increasing the appearance of texture and cleanliness. Ø 3, fill the water tank placed in the lower right control box, and a shortage of automatic protection, to facilitate the operator to add more water. Ø 4, a large observation window box attached to keep bright lights, and the use of heating element embedded glass, clear observation time inside the state. Ø 5, humidification system, piping and control circuit board separately, to avoid leakage due to wet pipe failure, to improve security. Ø 6, water system piping circuit system is used to open portal to facilitate the maintenance and repair. Ø 7, between the door and the box using double sheets of high temperature resistant seal to ensure that the test area closed. Ø 8, box on the left with diameter of 30mm or 50mm or 100mm of test holes for external test power line or signal line. (Diameter holes to increase the number of orders when the instructions). The bottom of the machine can be fixed with high quality PU wheels. Control system: Ø 1, temperature and humidity control devices with "Korea" full import of large screen images (5.7-inch LED display), the screen is simple, easy to program editing, no key input, direct touch-screen option. Ø 2, controller interface with Chinese and English are available, real-time operating curve can display. Ø 3, a 100 group program cycle step 1000 the capacity of 999 paragraphs, each time setting a maximum of 99 hours and 59 minutes. Ø 4, input data and test conditions, the controller has a screen lock function to prevent and stop human touch. Ø 5, with RS-232 or RS-485 communication interface, the computer design program to monitor test process and the implementation of Automatic Switcher functions. Ø 6, with automatic calculation of the function, changes in temperature and humidity conditions can be amended immediately so that more precise control of temperature and humidity stable. Cooling system: Ø 1, heating, cooling, humidification system is fully independent can improve efficiency and reduce testing costs, increase life expectancy, reduce the failure rate. Ø 2, cold machine French original, "Tai" all closed compressor. Refrigeration unit or binary type system uses low-temperature loop system. Ø 3, the United States and more powerful wing air circulation blower, to avoid any dead ends, make test temperature and humidity distribution within the region. Ø 4, Wind Road cycling the air return air design, air pressure wind speed are the test, and could open the door fast transient time, temperature and humidity stabilized.
