KOFLOC Purge Flow Meter with Needle Valve MODEL RK1000 SERIES
Quick Review
• KOFLOC RK1050 SERIES Compact Purge Variable Area Flowmeter
The KOFLOC Compact Purge Flow Meter with Needle Valve MODEL RK1050 SERIES is a small device especially suited for use as purge flowmeter or with scientific instrumentation. The new redesigned MODEL RK1050 SERIES retains all the advantages of MODEL RK1000 SERIES, but in an all-new design package.
• Wide flow range coverage
The KOFLOC Compact Purge Flow Meter with Needle Valve MODEL RK1000 SERIES comes in 4 sizes of 80, 100, 120 and 150 mm that cover flow ranges of 100, 150, 200, 300, and 500 ml/min, 1, 2, 3, 5, 10, 15 and 20 l/min.
• Low-price
The KOFLOC Compact Purge Flow Meter with Needle Valve MODEL RK1000 SERIES is small, simple and low in price, yet retains performance stability associated with more expensive high precision models. With its compact design, it can easily be accommodated into many scientific instruments.
• KOFLOC Dependability
KOFLOC has 60 years of experience in manufacturing precision flow instruments. KOFLOC products, both standard and off-catalog custom items are well received throughout Japan as the name that manifests confidence. KOFLOC, the fluid expert, is the name professionals trust in precision control of minute flow.
• Steel/ Brass fittings
The fittings are available in either SUS303/304 stainless steel or brass with respective O-rings of Viton® for SUS303/304 and NBR for brass fittings. The flow tube is made of Pyrex® and is enclosed in a protective cover of acrylic resin.
• Tri-flat & rib-guide flow-tubes
KOFLOC leads the industry in tri-flat flow-tube (for flows between 5 ml/min to 500 ml/min) production with superior precision. The rib-guide flow-tubes are used for medium range flows between 1 l/min and 50 l/min.
The KOFLOC Compact Purge Flow Meter with Needle Valve MODEL RK1000 SERIES can only be used for the following gases.
Medium (gases): Actual gas calibration is available for the gas listed
Air, Argon: Ar, Carbon dioxide: CO2, Helium: He, Hydrogen: H2, Nitrogen: N2, Oxygen: O2
N2 equivalent conversion factor (CF) is used for other gases.
