Kofloc Purge Flowmeter Model RK1000 Series

Purge Flowmeter (for Scientific Instrumentation System)

This is a glass tube float type flowmeter materialized through our all-out effort at streamlining the production line to offer users a low-cost model that can be shipped in a reduced period of delivery. While it is outstandingly compact(total length of the smallest type: 80 mm), it provides high performance in stability that bears comparison with any high precision models and is optimum to form a part of the customer's scientific instrumentation system.
