Product Details
>>Product Introduction
The walk-in constant temperature and humidity chamber adopts a * temperature and humidity control method to achieve temperature and humidity balance. It can accurately set the temperature and humidity environment, and can stably and evenly heat and humidify without damaging the machine. At the same time, it has a particularly large temperature and humidity control range, which can meet the needs of different users.
