Product description
The constant temperature and humidity chamber has an accurate temperature and humidity control system, which provides various simulated environmental conditions required for industrial research and biotechnology testing. It is widely used in pharmaceutical, textile, food processing and other sterility tests, stability checks and industrial products, raw material properties, product packaging, product life and other tests.
Features
The shell is made of high-quality cold-rolled steel plate, with electrostatically sprayed surface. The paint film is firm and the shape is beautiful.
The inner liner is made of mirror stainless steel, with four corners and a half arc design, which is easy to clean. The spacing of the partitions inside the box is adjustable. The left side of the cabinet is equipped with a Φ50 test hole for user’s inspection and external built-in device leads.
The control system adopts microcomputer temperature control technology and has 30-stage programming with high precision control. Ultrahigh brightness LED display makes all display values more intuitive.
It has an independent temperature limit alarm system, which will automatically interrupts when the temperature exceeds the limit temperature, ensuring safe operation of the experiment without accidents.
Use imported humidity sensor to avoid frequent replacement of wet and dry balls.
There is a power cord safety socket on the back of the device, a drain valve overflow on the bottom, with an external water supply and a bucket.
The printer and RS-485/232 interface and temperature limiter can be added before ordering according to user's requirements.
