With the development of the economy and the advancement of miniaturization and intelligence, customers demand a portable, field working car incubator. Its characteristics are handheld, using DC12V voltage, and an intelligent constant temperature incubator that can be directly plugged into a car cigarette lighter. Our company has undergone multiple research and development tests and successfully produced the BX series car incubator. Its conventional models are BX-200C-10L and BX-300C-15L, which have been well received by customers.
