    High-Precision Flowmeter (for Sensitive Measurements) MODEL RK 1450 SERIES


    This top-grade high-precision area flowmeter is a fruit of KOFLOC's challenge to boost the general perception currently conceived by people of flowmeter of being a "mere yardstick" into a new conception that a flowmeter is a "precision instrument." This flowmeter particularly features its uniquely precision-formed glass tube and ultra-precision ball float.

    Features
    - Capable of measuring ultra-minute flows
       Can measure a wide range of flows from ultra-minute flows of 0.5-3ml/min to flows of 3-30l/min.

    - High precision measurement

       High precision measurement of flows is available up to±2% of full scale (standard specification)or to±1% of full scale(optional specification).

    - Wide variations

       A broad range of variations is available in total length,materials of construction,flow rate,pressure,scale,and  so forth to meet diverse applications from a variety of fields.

    - Capable of measuring all kinds of gases
       Practically all kinds of gases can be measured,not to mention those standard(Air,N2,O2,H2,He,Ar and CO2).

    - Measurement of water flows also possible

       Measurement of full-scale water flows not exceeding 1l/min is also possible.(Dimensions may vary depending upon the specified maximum flow rate.) 

    Applications

    - For integration into your equipment panel

    - For flow inspections at laboratory

    - For semiconductor manufacturing equipment

    - For biotechnology industries
