New primary standard gas flow calibration systems

Sierra Instruments announced the introduction of the Cal=Trak SL-500 and Cal=Trak SL-800, a new line of portable low-maintenance primary standard gas flow calibrators.

Sierra Instruments announced the introduction of a new line of portable low-maintenance primary standard gas flow calibrators the Cal=Trak SL-500 and Cal=Trak SL-800.

Sierra, one of world's most preferred gas flow meter manufacturers, presents the much anticipated successors to its well-known, but discontinued Cal=Bench line of primary standard piston provers of the1990's.

The Cal=Trak SL-500 offers an excellent accuracy of +/-0.4% of reading while the Cal=Trak SL-800 offers the best accuracy of any commercially available standard: +/-0.15% of reading! Sierra customers use Cal=Trak in the manufacture, inspection, validation and recalibration of mass flow controllers, mass flow meters and numerous other varieties of gas flow measurement and control instrumentation.

Cal=Trak operates in the 5 sccm up to 50 slpm flow range.

The broad turndown ratio allows three interchangeable flow cells to cover the entire range.

Alternatively, the modular nature of the Cal=Trak allows the user to begin with one flow cell and then add other cells as resources allow--creating the need for only a minimal initial investment from the customer to get started.

Sierra's Cal=Trak line provides primary NIST traceability, is manufactured under strict ISO 17025 certification, and is CE approved.

The dimensionally-based primary accuracy of Cal=Trak is superior to pressure-based secondary methods and is backed by a rigorous uncertainty analysis.

Both Cal=Trak models offer data logging, digital communications, interval operation and many other productivity-enhancing features.

Fast enough to use as a flow meter, Cal=Trak is automatic and requires minimal training to get started.

It is well-suited for applications in the metrology, semiconductor, analytical, medical and pharmaceutical fields, among many others.
