Dwyer Pressure Gauges

Capsule-type differential pressure gauge (Capsuhelic) with analog dial display used to measure low differential pressure and airflow rates in HVAC and industrial ventilation systems.

Dwyer pressure gauges are available as differential pressure sensors and transmitters, analog differential pressure gauges, digital differential pressure gauges, mechanical pressure switches, and digital pressure switches for measuring air, gas, and liquid pressure in industrial, commercial, and HVAC systems.

Dwyer pressure gauges are known for their reliable performance, sturdy construction, and clear readability, making them some of the most trusted instruments in industrial, commercial, and HVAC applications. When a technician uses a Dwyer pressure gauge, they can be confident the instrument will provide a consistent, accurate reading for the operational pressure of any given system.

Dwyer manufactures both mechanical and electronic pressure gauges, with the majority of their models falling under the mechanical category. Their standard Bourdon tube mechanical gauges are well-regarded for affordability and durability, providing unfailing accuracy and clear readability even at a distance in basic industrial environments. Differential pressure gauges and switches monitor pressure differences between two points and are widely used in HVAC, filtration, and flow monitoring applications where precise threshold control and alarm outputs are required.
