Kofloc Flow Meter with Precision Needle Valve Model RK1200 SERIES

Description

The Kofloc RK1200 Series represents the pinnacle of manual flow control technology. Unlike standard plastic rotameters, the RK1200 is built with a precision-ribbed glass tube and a durable metal block (available in SUS316 or Brass), ensuring long-term structural integrity and measurement accuracy. The heart of the RK1200 is its high-performance needle valve, located at either the inlet or outlet. This valve is designed for ultra-smooth operation, allowing users to make minute adjustments to the flow rate without the “jumpiness” often found in lower-quality meters. The scale is expertly calibrated for specific gases or liquids, providing clear, parallax-free readings. Whether you are managing carrier gases for chromatography or regulating cooling water for high-vacuum equipment, the RK1200 series offers a reliable, “power-free” solution for precision fluid management.

The natural environment is preserved through the balance of solids, liquids and gases that exist on the earth. However, human civilization has caused pollution that has greatly damaged our environment. The task of the present generation is to restore our environment to its natural healthy state. And this is also the greatest challenge for 21st century science and technology.

KOFLOC's corporate motto is "A Scientific Approach for Fluids." In other words, we create products that scientifically measure and control the balance of liquids and gases. We trust that through our work we are making a contribution to the regeneration of the environment and to the establishment of a prosperous society.
