Mass Flow Controller delivers instant-on, real-time operation.

Press Release Summary:

Designed for original equipment manufacture and process integration, 20SLPM BASIS™ model controls gas flow rates. BASIS series, featuring instant on technology, offers models with FS at 100 cm³/min and 1 or 20 Lpm. Models perform at full accuracy within 70 msec, and 100 msec control response enables real-time reaction to upstream fluctuations. Multi-gas and single-gas units offer NIST-traceable accuracy of ±(1.5% of reading + 0.5% FS) as well as multiple communications options.

Alicat Adds 20SLPM Model to BASIS(TM) Mass Flow Controllers

Compact, reliable gas flow for OEM and process use

Tucson, Arizona – Alicat Scientific has expanded its BASIS™ line of mass flow controllers, adding a new 20SLPM model to fit a wider range of applications including sparging into liquids, sample dilution, and many gas mixing applications. Specifically designed for original equipment manufacture and process integration, BASIS is Alicat’s smallest footprint instrument, providing fast, accurate control of gas flow rates in an economical, easy-to-integrate package. Ideal for use in OEM gas analyzers, automated gas mixing on process lines, and anywhere basic mass flow-only control is required, the BASIS family now offers models with full scale at 100 cubic centimeters per minute, 1 liter, and 20 liters per minute.

Stocked and ready for quick ship on evaluation orders, all BASIS units are instantly on and performing at full accuracy in just 70 ms. A 100 ms control response enables BASIS to react in real time to upstream fluctuations. NIST-traceable accuracy is +/-(1.5% of the reading + 0.5% full- scale).

BASIS is available with the following multi-gas calibrations: Air, Ar, CO2, N2, O2, N2O (selectable over serial connection); He, H2 are also available in single-gas units. Multiple communications options – RS-485, RS-232 and Modbus Serial; and 0-5 Vdc analog – mean BASIS can be built into a broad range of end-user products. For process applications, the availability of analog and digital feedback allows for both PLC and PC control options.
