CalTrak® 500 Modular Gas Flow Calibrator
High-Accuracy Primary Standard for Cal Labs & Industry
Sierra's CalTrak® 500 is a high-accuracy, modular primary standard gas flow calibrator for all inert gases. Fast and portable, the 500 offers standardized accuracy of ±0.35% for customers who have many flow instruments to be validated or calibrated frequently. Primarily used for standard calibration and verification of mass flow meters, controllers, variable area flow meters, and precision in-situ calibration of industrial flow meters and controllers.
The 500 is a true primary standard in every sense of the word. The dimensionally-based primary accuracy of the CalTrak surpasses pressure-based secondary methods and is backed by a rigorous uncertainty analysis. For the most stringent accuracy, the 800 is manufactured to ISO 17025 standards at a NVLAP accredited lab using assets that are directly traceable to NIST.
For flexible use, the modular 500 has three interchangeable flow cells with a broad turndown ratio to cover the entire range, minimizing initial investments and maintenance costs. This modular design allows users to begin with one flow cell and then add the other cells as resources allow. CalSoft® software captures the flow data from your 500 for easy export into common software packages, a PC or Microsoft environment.
