Sierra's CalTrak® 500 and 800 are modular piston provers that offer portability and low-maintenance for customers who have many flow instruments needing to be validated or calibrated frequently. Each system comes with a base unit and choice of flow cells fitted with low mass-borosilicate glass pistons with a low friction coating that oscillate between two detectors to quickly and accurately measure gas flow rates. The design of the CalTrak 500 and 800 allows for increased flexibility and speed of reading. The CalTrak 500 consists of a base and three interchangeable flow cells. The CalTrak 800 series consists of a base and five interchangeable flow cells. Each cell has a specific range. Cells can be easily changed (no tools needed) within seconds and can be purchased separately. Cells for the model 800 can be used only with the 800 base. Cells for the 500 can be used only with the 500 base. Flow measurements can be taken manually (one reading at a time), or automatically in continuous mode. CalTrak calibrators offer digital communications via RS-232 and USB and come with our CalSoft™ complete data collection software suite. Make CalTrak a workhorse in your calibration lab and save money by doing your o

Figure 1: CalTrak 500 & 800 - Standard CalTrak 500 and 800 are a true primary standard in every sense of the word, because their accuracy is based upon primary SI units: The interior diameter of the glass measuring cylinder; the length of piston travel within the cylinder; and the time it takes the piston to travel this distance, implying a known volume. Our patented technology, therefore, offers accuracies at the level of national laboratories in one portable device. Sierra's CalTrak models contain a nearly frictionless graphite piston that moves freely inside a borosilicate glass tube. When...
