Frequently Asked Questions

A Dwyer gauge is a precision instrument used to measure pressure, vacuum, or differential pressure in HVAC, cleanrooms, filter monitoring, and industrial applications. Popular models like the Magnehelic® gauge offer reliable, low-pressure measurements and are widely used for their durability and accuracy.

To calibrate a Dwyer Magnehelic® gauge, connect it to a known pressure source and compare readings to the standard. Adjust the zero and span screws as needed. Calibration should be performed by trained technicians using traceable equipment to ensure accuracy and compliance with industry standards.

The Dwyer differential pressure indicator measures the difference in pressure between two points. It’s commonly used in air filters, duct systems, and cleanrooms to monitor airflow, pressure drops, and ensure optimal system performance. Models include both analog and digital indicators with easy-to-read displays.

A Dwyer manometer measures low-pressure air or gas systems. It’s used in HVAC balancing, leak testing, and filter monitoring. Dwyer offers both inclined and digital manometers known for their high sensitivity, ideal for applications requiring precise differential pressure measurement.

To set a Dwyer pressure switch, adjust the setpoint using the external screw or dial according to your required pressure range. Connect the switch to a pressure source and monitor its activation point. For precise operation, it’s recommended to follow the manufacturer’s manual or consult a technician.

Dwyer instruments themselves are not NATA-certified, but HK Calibrations offers NATA-accredited calibration for Dwyer products. This ensures your Dwyer pressure gauges, manometers, and switches are accurately calibrated and traceable to national standards, suitable for audits and compliance.

To use a Dwyer digital manometer, connect the pressure source to the input ports, power on the unit, and select the appropriate measurement mode or unit. Read the digital display for pressure values. It’s ideal for field use in HVAC testing, gas line checks, and cleanroom monitoring.
