Purpose: HL-80-70M programmable constant temperature and humidity tester 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. Characteristics: Appearance: high texture appearance, the body adopts arc shape, the surface is treated by fog surface stripe, and the plane no reaction handle, easy to operate, safe and reliable. Observation window: rectangular double-layer glass viewing window, can be used in the test, the window has anti-perspiration electric heater device to prevent water vapor condensate water drop, and high brightness PL bright light to keep the light in the box. Water supply system: external water supply system is convenient for replenishing humidified buckets and for automatic recycling. Compressor: the compressor circulates the system to adopt the French "Taikang" the brand, can remove the condensate tube and the capillary oil and the entire series effectively, uses the environmental protection cold coal R404507) Control mode: intelligent PID SSR/SCR forward and inverse two-way synchronous output, including advanced slope control logic. Controller: with multi-stage program editing and temperature, humidity can be used for quick OUICK or slope control. System capacity: can log in 150 groups of programs × 1500 segments, the number of segments can be arbitrarily divided, programs can be freely connected with each other. Cycle setting: 9999 x 9999 cycles can be performed, and 5 separate partial cycles can be cut out. Time signal: 3 groups of timing control output interface, with 10 kinds of time control mode, easy to perform external driving components start / stop timing planning. Safety check: 15 full-featured system detections to ensure safe operation of the machine. And can automatically display fault time, items and troubleshooting countermeasures. Technical parameters: Model: HL-80-70M Internal dimensions (W × H ×D) cm: 40 × 50 × 40 External dimension (W × H ×D ) cm:93 × 131 × 81 Volume L): 80L 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 : A one - element fully enclosed air - cooled refrigeration system is adopted at -20 ℃ , and a binary fully enclosed air - cooled refrigeration system is adopted below -40 ℃ . Water supply system: built in pure water generating device, without manual adding water, can run water directly, and attach water shortage warning device Inside and outside material: SUS#304, whole 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
