Feature: Fermentor is simens' PLC control system, and this system adopts simens'human-machine interface(HMI) and PID control, which can measure and automatically control parameters of temperature, rpm, pH, DO, feed, foam and etc. It possesses functions of digital setting, quick validation, data display, data storage, data print, password management and so on. It has commucation connection which can communicate with computer.

Struction: From lab scale to pilot scale, floor stand ,two different fermentors vessel with one control system

Range:
This series of products suit for various kinds of microbiology fermentation test, such as bacteria culture, vaccine, fungi, enzyme, environmental, agricultural, pharmaceutical, and micro biological ,etc. Equipment has the following features: Excellent stability and convenient operation. User can choose appropriate configuration according to fermentation process.
