Temperature and humidity chamber, also known as constant temperature and humidity testing machine, constant temperature and humidity test box, constant temperature or humidity chamber for detecting material under a variety of environmental equipment and test the performance of a variety of materials, heat, cold resistance dry and wet performance. Suitable for electronic, electrical, communications, instrumentation, vehicles, plastic products, metals, food, chemicals, building materials, medical, aerospace and other products quality testing purposes.
  Temperature and humidity chamber by a thermostat (heating, cooling) and humidification of two parts. At the top of the cabinets by installing a rotating fan, air is discharged into the box to achieve gas circulation, balance cabinets temperature and humidity, the built-in cabinet temperature and humidity sensor data acquisition, spread of temperature and humidity controller (Micro Information Processor) for editing process, temperature and humidity instruction issued by the air heating unit, as well as within the condenser heat sink together to complete evaporation unit.
  Humidity Chamber temperature is regulated by the cabinet built-in temperature sensor, data acquisition, the temperature controller (Micro Processor) adjust, turn the air heating unit to achieve increased temperature or regulating valve to reduce refrigeration cabinets temperature to to reach the desired temperature control. Humidity Chamber body temperature is regulated by built-in temperature sensor, data acquisition, the humidity controller (Micro Processor) adjust, turn tank heating element, by evaporation of water inside the tank to achieve increased humidity or adjust refrigeration cabinets solenoid valve to achieve dehumidification, in order to control the desired humidity.
  Humidity Chamber with multiple protection measures; temperature of the system can be set at the maximum safe temperature conditions allow, equipped with over-temperature protection, air heating element can automatically power down with the rotation of the fan is stopped; humidification system with humidification water tank reduce and stop power supply; refrigeration systems with cabinet temperature (over 40 ℃) or increasing humidity and stop working.
Environmental conditions
  Temperature: 5 ℃ ~ + 35 ℃ (within 24 hours the average temperature ≤28 ℃);
  Relative humidity: ≤85% RH;
  Pressure: 86kPa ~ 106kPa;
  Phase four-wire power supply conditions + protective earth, voltage range: AC (380 ± 38) V;
  Frequency allows the fluctuation range: (50 ± 0.5) Hz;
  Protection of ground grounding resistance of less than 4Ω;
  It requires the user to configure the capacity of the installation site of the air or power switch for the device, and this switch must be independent of the equipment for use;
  Water conditions: The device requires the use of pure water humidifying water.
