High-Grade Mass Flow Meter
Model 3200 Seires
Model 3200 Series Mass Flow Controller is an advanced model designed as a successor of the 3910 series that enjoys a wide use for diverse applications such as manufacture of semiconductors, LCDs, combustion equipment, analytical devices, and biotechnology fields. Its high performance is equal to a new standard of KOFLOC
Features
- Equipped with a temperature follow up type current difference detection flow snesor (patent applied for) to ensure high accuracy and high-speed response
- Use of a normally closed valve to ensure safety
- Reduced dead volume thanks to the diaphragm seat valve
- Control of small quantities of flows available up to 1 SCCM full scale (SR option)
- Low differential pressure type control available for cimbustible gases (LP option)
Standard Specifications
Note
Specification relating to the flow range (e.g., flow range, accuracy and response) are expressed in N2 or air equivalent. The product will be built with the primary pressure of 300 kPa or less and the secondary side open to the atmosphere. For details on the pressure requirements, please contact us.
