Bio-process specialist CENTRION









Looking at the MFC flow rate of the flow rate value through a digital display, a device for controlling the flow rate through.

Air or gas required for fermentation and culture (O2, CO2, N2, etc.) are automatically controlled to a desired flow rate through the MFC is supplied to the vessel.  

Small Size Flow Controller MFC. Combining small size flow sensor MFC and small solenid valve technology. 

High performance and cost efficiency incorporated in sensor, proportional control, and valve functions enable use with different applications. Compatible with different fluids.

Gas sensor is providing modern and inexpensive measuring solutions for in-situ analysis of bioprocesses with its Gas sensor series. 

Gas sensor is quick and easy to integrate into processes, providing readings with a high level of reliability. All analyzers in the series unite several measureing components in one compact stainless steel housing.

The measuring signals can be exported as analog signals (4-20mA each for both signals) as well as digital signals (RS485 Modbus, RS232, usb). Data can be logged during measurement using an optional web server, and is very easy to display when needed in any up-to-date browser via a network connection. Using the data bus module RS485, Several analyzers can be connected at once, allowing parallel systems to be activated and making readouts straightforward.

The Balance internal calibration with an internal mass saves time and money. External calibration requires a great deal of skill and time as well as an expensive external mass.

With our internal calibration with internal mass, the balance can be calibratedevery quickly.

Automatic self calibration - Self-calibrates automatically when the balance on demand with just the push of a button.

Easy-to-use optional USB interface, with no driver or software installation necessary, for transfer or weighing data to a computer (Unidirectional communication from a balance to a PC only. Please use the standard RS-232C interface for sending commands from a PC to the balance.)
