Get unsurpassed Primary Standard Gas Flow Calibration capability with the portable and low-maintenance 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 ±0.35% of reading while the Cal=Trak SL-800 offers the best accuracy of any commercially available standard: ±0.15% of reading!
Any flow instrument operator can 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, minimizing initial investment and maintenance costs. 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
