Multiple Flow Meter with Needle Valve(for Precision Measurement and Control for Laboratory)
Model RK120X SeriesThis multiple flow meter with a needle valve is made by combining several types of flow meter for controlling various flows in a laboratory. It is designed based on the RK1200, a flow meter with precision needle valve, and has been verified to have outstanding reliability.
Features
- Multiple control of two to four flow meters
Two to four flow meters can be attached to one unit to permit control of various gases in various flow ranges. - Various flow ranges
The flow meter can measure a variety of flows ranging from the very small flow of full-scale 5 ML/MIN to 20 L/MIN - High-precision measurement and control
This flow meter is designed based on the precision flow meter RK1200 and permits control of very small flow and high-precision measurement (FS±2%).
Applications
- Control of multiple components
- Multiple range control
- Flow control in laboratories
