•KOFLOC Dependability
KOFLOC has 60 years of experience in manufacturing precision flow instruments. KOFLOC products, both standard and off-catalog custom items are well received throughout Japan as the name that manifests confidence. KOFLOC, the fluid expert, is the name professionals trust in precision control of minute flow.
•Standardized Dimensions and Parts
The KOFLOC Low-Cost Metal-Sealed Mass Flow Controller/Meter MODEL 5400 SERIES retains the standard 3 in (76 mm) footprint, regular fittings and common electrical signal settings to easily replace and fit into existing gas lines without any modifications for use in widest possible applications.
•Quick Response
The KOFLOC Low-Cost Metal-Sealed Mass Flow Controller/Meter MODEL 5400 SERIES is equipped with the new temperature-tracing current differential sensor (P.A.F) for high accuracy at 1% F.S. or less and quick response of 0 ~ 100% in 1 s or less.
•Low-Leak Structure
The KOFLOC Low-Cost Metal-Sealed Mass Flow Controller/Meter MODEL 5400 SERIES has a metal-sealed, no-weld structure to achieve low-leak at 1x10-11 Pa.m3/s or lower.
•Low Pressure Model
The KOFLOC Low-Cost Metal-Sealed Mass Flow Controller/Meter MODEL 5400 SERIES has a standard low-pressure differential option especially suited for applications of burn control.
•Low-Cost & High Performance
The KOFLOC Low-Cost Metal-Sealed Mass Flow Controller/Meter MODEL 5400 SERIES meets or surpasses standard performance requirement of no-welding, metal seal, 1% accuracy at full scale and response time of 1 s or less at full scale in gas control of semiconductor processes. This mass flow controller/ meter has achieved low-cost on top of all these. The MODEL 5400 SERIES stands out is its general usefulness in a wide and varying fields and specialties, fromCCFL (Cold Cathode Fluorescent Lamp) production lines of LCD backlights to analytical applications, such as in bioethanol evaluation using an ICP-MS (Inductively coupled plasma mass spectrometry).
