Multi-Channel Mass Flow Controller (MFC) / Meter (MFM) for Gases
Type 8735 forms the basis of the modular and economical multi-channel flow control systems for gases. The semi-standardized modular system consists of assemblies that can be put together flexibly and according to requirements. The heart of the system are the thermal mass flow controller/ meter (MFC/ MFM) for gases. Type 8735 thus enables tailor-made solutions without generating long development times and development costs.
Type 8735 multi-channel MFC/MFM systems are aimed at applications with several control loops and high volumes. For example, laboratory analysis equipment for spectroscopy or gas chromatography.
