Description
The tetraCal is a simple-to-use, NIST Traceable Standard for volumetric air flow, barometric pressure and ambient temperature.
Close Information
The tetraCal system is designed to tolerate a wide range of adverse field conditions including hot and cold temperatures as well as high relative humidity. The field portable tetraCal is the perfect solution for calibrating environmental and industrial hygiene air sampling instruments.
To use the tetraCal, simply connect the tetraCal and the sampling instrument with tubing and media installed and turn them both ON. The tetraCal immediately begins providing the flow rate and ambient condition data on the screen. There are no bubbles, sticking pistons or insurgent pressure spikes to worry about.
The tetraCal is a venturi based system with built-in compensation for changes in ambient temperature and pressure. The system is designed to be invisible to the instrument being calibrated, with no moving parts. Three ventura are available to cover a total flow range from 0.1 to 30 lpm.
The tetraCal is the only field calibration device which meets the same temperature criteria as EPA designated samplers. This is a dynamic temperature range from -30 to 40°C and each kit includes software that allows for data storage and reporting. All tetraCal systems are built and tested at the factory which is both a NIST Certified Calibration Laboratory and an ISO 9002-2000 facility.
APPLICATIONS
Simple ON/OFF operation - all data displayed on screen automatically
