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

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
