Kofloc EX-700 is a EXE-FLOW family digital mass flow meter with display. The EX-700 mass flowmeter is suitable for N2 gases application.
Kofloc EX-700 Digital Mass Flow Meter with Display the EXE-FLOWTM was commercialized “Exact measurement” and “Excellent function as a concept. This is covered from a small flow rate (F.S.10sccm) to a large flow rate (F.S.200slm) and the 11 flow ranges are ready as s standard stock.
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.
