Kofloc Mass Flow Controllers Model HFC-303 SERIES

The Kofloc Model HFC-303 Series is engineered for applications where speed and accuracy are non-negotiable.

Description

The Kofloc Model HFC-303 Series is engineered for applications where speed and accuracy are non-negotiable. While standard controllers often exhibit “hunting” or long stabilization times, the HFC-303 utilizes a high-sensitivity bridge-type thermal sensor and sophisticated digital processing to ensure a smooth, instantaneous flow ramp.

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.
