Purpose: TS-91 constant temperature and humidity test box is used to test the performance of materials in various environments and to test the heat, cold, dry and moisture resistance of various materials. Suitable for electronic, electrical, communication, instrumentation, vehicle, plastic products, metal, food, chemistry, building materials, medical, aerospace and other products testing quality. Product features: 1, 3 computer integrated design method, easy to use, do not occupy space. 2. Each test area can test three different control conditions: high temperature, low temperature or constant temperature and humidity. 3, all systems are individually independent: three sets of refrigeration system, three sets of heating and humidification system, three sets of control system, so the control is stable, the accuracy is high, and the service life of the machine can be prolonged. 4, touch setting mode, completely controlled and locked by microcomputer, and has the function of automatic calculation of PID value Test criteria: GB-2423.1-89 IEC68-2-1) Test A: test method for low temperature GB-2423.2-89 IEC68-2-2) Test B: high temperature test method High temperature life test of GJB360.8-87 MIL-STD-20F High temperature test method for GJB150.3 / MIL-STD-810D GJB150.4 MIL-STD-8101D) low temperature test method Test Ca3: constant hygrothermal test method Test Db: alternative damp heat test method GJB 150.9-93 MIL-STD-810D) wet heat test method Technical parameters: Model: TS-91 Internal dimension W × H × DX cm: 91L: W450H450 D450mm (wide * high * deep) External dimension W × H × DU cm: W1300 H1950 D1150mm (wide * high * deep) Volume L): 91L Heating rate: 0 ℃ ~ 100 ℃ ~ 20 ℃ ~ 100 ℃ ~ 35 min ~ 40 ℃ ~ 100 ℃ 45 min ~ 70 ℃ ~ 100 ℃ about 60min Cooling rate: 20 ℃, 0 ℃, about 20 min, 20 ℃, 20 ℃, 20 ℃, about 45 min, 20 ℃, 20 ℃, 40 ℃, about 60 minutes, 20 ℃, 20 ℃, 70 ℃, about 90min. Temperature range: 0 ℃ -20 ℃ -40 ℃ -70 ℃ / 150 ℃ Mean temperature distribution: ±0.5 ℃ Average humidity distribution: ±3% Temperature stability: ±0.3 ℃ Humidity stability: ±2.5%RH Humidity range: 20 RHs can be customized according to customer requirements: low humidity can reach 5 RHs) Program control: 120-group 1200 segment programming with 999-cycle setting, with multi-group PID control function and RS-232 computer interface control. Humidification system: surface evaporation type, with humidifier water shortage and protection against overheating. Dehumidification system: refrigerated latent heat dehumidification method Cooling system: -20 ℃ above 20 ℃ with one-unit airtight air-cooled refrigeration system or below -40 ℃ using binary fully closed air-cooled refrigeration system Water supply system: built in pure water generating device, without manual adding water, can run water directly, and attach water shortage warning device Material: SUS#304, stainless steel Insulation material: rock wool and rigid pu foam insulation Safety devices: fuse free switch, compressor overload, cold coal height, overheating, power failure, protective switch, temperature limit protection and fault alarm device Temperature and humidity Adjustment: a balanced way of regulating temperature and humidity Standard equipment: automatic fogging glass window, up and down adjustable two layers, test hole, operating indoor lamp, moving wheel Purchase equipment: recorder Power: AC220V/380V ±10 / 50 / 60 Hz
