Highest Accuracy Gas Flow Calibration Primary Standard
CalTrak®800
- Highest accuracy of ± 0.15% of reading gas mass flow rate
- Broad flow range from 0.5 sccm up to 100 slpm
- Quick, easy to use, automatic data capture
- Portable and battery operated
- Results directly traceable to NIST
Overview
Bring the world’s most accurate flow standard to your lab with the CalTrak® 800. The 800 is used for calibration and verification of:
- Mass flow meters
- Controllers
- Variable area flow meters
Also used for the precision in-situ calibration of industrial flow meters and controllers, the 800 is ideal for customers who require the very best flow meter accuracy to do their job right. Avoid the cost and downtime delay of sending out instruments to be calibrated with the CalTrak 800, perfect for owners and users of many flow instruments (more than 25) that require calibration/verification one or more times a year.
Every 800 is manufactured to ISO 17025 standards at a NVLAP-accredited lab using assets that are directly traceable to NIST.

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. 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.
