Choose What’s Best for You

Accurate, reliable air flow is a must-have to meet today’s IAQ requirements—especially for the health and comfort of building occupants. But whether it’s a new installation or a retrofit, every project is unique. To suit your needs, we offer two methods to measure and control HVAC air flow: differential pressure and thermal dispersion.

Accurate

Choose between differential pressure and thermal dispersion to fit your unique needs.

Compliant

Helps you meet IAQ requirements for minimum ventilation.

Highly Efficient

Airflow measurement with top-quality performance.
