Overview
Sierra’s CalTrak® 300 is an economical, portable primary standard gas volume flow calibrator for inert gases designed to meet the demands of industrial hygiene and occupational health professionals. The 300 is ideal for quality control in the manufacturing of respirator equipment, personal sampling pumps and other hygiene equipment. The calibrator is manufactured to ISO 17025 standards at a NVLAP accredited lab using assets that are directly traceable to NIST. The dimensionally-based primary accuracy of the 300 surpasses pressure-based secondary methods and is backed by a rigorous uncertainty analysis.
Operating principal:
All of our CalTrak models contain a nearly frictionless graphite piston that moves freely inside a borosilicate glass tube. When the parallel bypass valve is closed, the gas flow is directed into the tube to push the piston up (Note: Draw new figure 1 from datasheet and add). Two photo-optic sensors detect the piston as it travels past.
The distance the piston travels between the two sensors is precisely defined and represents a known volume. Accurate crystal-based timers drive a microprocessor which calculates the rate of rise. This defines the volumetric flow rate. At the same time, extremely accurate temperature and absolute pressure sensors collect data used to calculate the mass flow rate.
