BASIS is the company's smallest footprint instrument, providing fast, accurate control of gas flow rates in an economical, easy-to-integrate package. It is suitable for use in OEM gas analysers, automated gas mixing on process lines, and anywhere basic mass flow-only control is required.

All BASIS units are ready to control process flows at full accuracy in just 70 ms. A 100ms 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 RS-485); He, H2 are also available in single-gas units. Dual communications – RS-485 Serial and 0-Vdc analog – mean BASIS can be built into a range of end-user products. For process applications, the availability of analogue and digital feedback allows for both PLC and PC control options.
