tetraCal NIST Volumetric Air Flow Calibrator Overview
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
- May be used on any sampler in the 0.1 to 30 lpm range
- Usable in the field or laboratory
- Calibration & audits of Speciation Samplers to U.S. EPA requirements
- Suitable for calibration of 1 ACFM cascade impactors
