Sierra instruments introduces Cal=Trak, ideal for anyone who wants to guarantee gas flow calibration quality and save money! Now for the first time, a primary gas flow calibrator, as used in the highest level metrology and flow calibration laboratories worldwide, is available in a compact, easy to use and extremely reliable package. Cal=Trak is made with 30 years of gas flow experience and the latest knowledge and materials available. The accuracy and performance of the highest level calibration laboratories can now be part of your laboratory, workshop or production floor.

Fast, primary, affordable, Mercury-free and easy-to-use, the Cal=Trak™ SL-500 offers a standardized 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. 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 5 sccm to 50 slpm range.

The broad turndown ratio of the SL-500 allows three interchangeable flow cells to cover this range, minimizing 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.
