Minihelic Gauge

Minihelic gauges are commonly used for measuring the differential pressure across applications such as blower pressure, air velocity, differential room pressures, Heating, Ventilation and Air Conditioning (HVAC) Systems. The simple, frictionless gauge movement quickly indicates low air or non-corrosive gas pressures – either positive or differential. The design resists shock, vibration and over-pressures.
