The KOFLOC RK1600-SS-CC-1/4-Air-20/30-L/min is a high-precision variable area flowmeter (Rotameter) belonging to the acclaimed RK1600 series by KOFLOC (Kojima Instruments Inc., Japan). Renowned for its solid mechanical design, elegant appearance, and exceptional responsiveness, the RK1600 series delivers smooth, highly accurate flow regulation across both industrial lines and advanced research laboratories.

Constructed with high-grade Stainless Steel (SUS) wetted parts, the unit provides superior resistance to corrosion and environmental degradation, paired with a heavy-duty Borosilicate Pyrex glass metering tube for crystal-clear readability. The graduated scale is precisely laser-etched to resist fading over time, enabling operators to visually assess flow rates with confidence. Equipped with an integrated micro needle valve, it ensures smooth flow adjustments under working pressure conditions of 0.1 MPa to 0.3 MPa. This model represents a top-tier choice for electronics assembly, semiconductor manufacturing, optical device fabrication, and precision automated pneumatic systems.
