Quick Review
•Separate LED Display
The KOFLOC Mass Flow Controller / Mass Flow Meter with Indicator, MODEL 8500 SERIES can be specified to include a separate LED display, which allows remote readings and flow settings from a distance of 1, 3 or 5 m.
•Hazardous Gases Capability (Rohs Compliance)
The KOFLOC Mass Flow Controller / Mass Flow Meter with Indicator, MODEL 8500 SERIES can be used to measure hazardous gases, because its thermal mass flow sensor is isolated from the flow medium. Selection of SUS316L/SUS316 stainless steal and Viton® EPTFE/Neoprene elastomer seals is available.
•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.
•RS485 or RS232C
The KOFLOC Mass Flow Controller / Mass Flow Meter with Indicator, MODEL 8500 SERIES offers a choice of RS485 for good flexibility in configuration especially when using multiple units. RS232C is also available to ensure backward compatibility when replacing and older mass flow controllers and meters in existing gas lines.
•Totalizer and Auto-Zero
The totalizer and auto-zero functions are standard features of every KOFLOC Mass Flow Controller / Mass Flow Meter with Indicator, MODEL 8500 SERIES as well as 5 instant flow presets and 2 flow alarm outputs.
•Standardized Dimensions and Parts
The KOFLOC Mass Flow Controller / Mass Flow Meter with Indicator, MODEL 8500 SERIES retains the standard 3 in (76 mm) footprint, regular fittings and common electrical signal settings to easily replace and fit into existing gas lines without any modifications for use in widest possible applications.
•MODEL 8500/8550
The KOFLOC Mass Flow Controller / Mass Flow Meter with Indicator, MODEL 8500 SERIES lineup actually comprises of 2 units, the 8500 for max. flow rate between 10 sccm ~ 20 slpm, and the 8550 for flows of up to 30 slpm ~ 100 slpm.
•Universal Flexibility
One aspect of The KOFLOC Mass Flow Controller / Mass Flow Meter with Indicator, MODEL 8500 SERIES, which stands out is its general usefulness in a wide and varying fields and specialties, from CCFL (Cold Cathode Fluorescent Lamp) production lines of LCD backlights to analytical applications, such as in bioethanol evaluation using an ICP-MS (Inductively coupled plasma mass spectrometry).
