Kofloc Mass Flow Controllers Model 8700 SERIES

The Kofloc Model 8700 Series is designed to meet the rigorous demands of modern fluid management.

Description

The Kofloc Model 8700 Series is designed to meet the rigorous demands of modern fluid management. At its core is a high-sensitivity thermal mass flow sensor that measures gas flow independently of temperature and pressure variations. This sensor is paired with a fast-acting, high-resolution proportional solenoid valve that allows the controller to reach its set-point stability in 2 second.

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.
