 Programmable constant temperature and humidity chamber to control temperature and humidity within the price 

 Constant temperature and humidity chamber is the product on the required temperature and humidity, look at the product temperature, low temperature, and humidity resistance capability, then the constant temperature and humidity also have heating, cooling, humidification, lower humidity capabilities. 

 Heating device is to control the temperature constant temperature and humidity is key; it is to be heating up the controller will command the output voltage to the relay, about 3-12 volts DC added to the solid state relay above; its AC side equivalent to the wire connected; contactor also pull the heater voltage to both ends of heat, the circulation driven by the heat to the fan box, so that constant temperature and humidity temperature, that temperature almost reached your settings; controller by adding the solid-state relay on-off regulation; we see on the screen at constant temperature and humidity contribute to how much to adjust the heating heat; it is 89 degrees in temperature control, in 89 degrees below the temperature stability of how to control it? Constant temperature and humidity in the side of the heat output by the number of solid-state relays; another compressor refrigeration cycle cooling up through the dynamic equilibrium; temperature constant. 

 Cooling is an important part of constant temperature and humidity is a constant temperature and humidity to determine the quality of key performance parameters, which includes compressor, condenser, throttling device, evaporator four major components. Compressor is the heart of the refrigeration system, which inhalation of low-temperature low-pressure gases into high pressure gas, the heat released by condensation into a liquid, through the fan away the heat, so the hot air causes constant temperature and humidity is below, and then cutting to the low-pressure liquid , followed by low-temperature low-pressure gas into the evaporator and back to the compressor; refrigerant to absorb heat in the evaporator to complete the process of re-gasification and absorption of heat, cooling to achieve the purpose of constant temperature and humidity to complete the cooling process. 

 Humidification systems and heating systems are similar; it is the process heater heating water into steam; complete constant temperature and humidity humidification purposes. 

 Lower humidity system is completed by the refrigeration system, evaporator placed in constant temperature and humidity inside; relatively cold, constant temperature and humidity inside the humid air meets cold object into a liquid condensate; so again little box experience high humidity, purpose to achieve lower humidity.
