Large-screen LCD display, multi-group data display on one screen, menu-style operation interface, easy to understand and easy to operate.
Temperature and humidity control adopts digital display multi-segment program control technology with high precision and no overshoot.
PID control mode, accurate temperature control and humidity control with small fluctuations.
If the temperature exceeds the limit, the operation will be automatically interrupted, and the audible and visual alarm will remind the operator to ensure the safe operation of the experiment without accidents.
The cabinet and working room are designed with circular arc structure.
The studio is made of mirror stainless steel, and the shelf can be adjusted in height and assembled freely, which is convenient for cleaning in the studio.
The outer box is treated with plastic, the whole machine is beautiful, generous and reasonable, and it is easy to use and maintain.
Brand compressors, self-developed compressor cooling system, can effectively prolong the service life of compressors.
The JAKEL tube flow circulation fan is used, coupled with a uniquely designed air duct structure, to create a good air circulation system and effectively ensure the temperature uniformity in the box.
Brand humidity sensor, external humidification system, effectively guarantee the humidity deviation.
Equipped with leakage protector.
An auxiliary thermostat is installed to ensure that the product can still work normally (for heating) when the main temperature control is out of control.
The program has 99 cycles, each cycle is divided into 30 segments, and each cycle is 99 hours and 99 minutes, which can meet almost all complicated experimental procedures. (optional)
With USB or RS485 interface, it can be connected to a printer or computer, and can record the change of temperature parameters. (optional)
