The prominent dial is easier to read from a distance than a standard scale.

Rated for at least six times the pressure of standard flowmeters for air, these can withstand pressures of at least 600 psi.

Choose these flowmeters for highly accurate flow rate measurements.

The correlated scale and conversion charts let you use the same flowmeter for nitrogen, oxygen, argon, and helium.

With a probe on a cord, these meters access hard-to-reach places in duct.

This meter is often used to test airflow through supply and return grilles and air filters.
