Litre Meter has announced the introduction of the Cal Trak SL-500 primary standard gas flow calibrator, the first in Sierra new Cal Trak line of high-precision, cost-effective, primary standard gas flow calibrators.
Sierra Instruments presents the successor to its well-known, but discontinued Cal Bench line of primary standard piston provers of the1990s.
Fast, primary, affordable, mercury-free and easy-to-use, the Cal Trak SL-500 offers a standardised accuracy of +/-0.4% in a portable, low-maintenance flow calibrator.
The dimensionally-based primary accuracy of the Cal Trak is superior to pressure-based secondary methods and is backed by a rigorous uncertainty analysis, says Litre Meter.
Field-rugged, it is used in the manufacture, inspection, validation and recalibration of mass flow controllers, flow meters and many other varieties of flow equipment in the 5sccm to 50slpm range.
The broad turndown ratio of the SL-500 allows three interchangeable flow cells to cover this range, minimising initial investment and maintenance costs.
Alternatively, the modular nature of the Cal Trak SL-500 allows a user to begin with one flow cell and then add the other cells as resources allow.
Sierra's Cal Trak family provides primary Nist traceability, is manufactured under strict ISO 17025 certification, and is CE approved.
The Cal Trak SL-500 offers data logging, digital communications, interval operation and many other productivity-enhancing features.
Fast enough to use as a flow meter, Cal Trak SL-500 is automatic and requires minimal training for flow meter verification and calibration.
It is well-suited for applications in the metrology, semiconductor, analytical, medical and pharmaceutical fields, among others.
