Manometers & Differential Pressure Gauges

Manometers & Differential Pressure Gauges for HVAC/R

If you’re chasing airflow problems, nuisance pressure-switch faults, or you need clean commissioning numbers, a good manometer makes the job quicker and the diagnosis clearer. This range covers common HVAC/R use cases like duct static pressure, differential pressure across filters/coils, and (where applicable) gas pressure checks.

What you’ll find in this collection

• Pocket and handheld manometers for quick static/differential checks
• Dual-port options for pressure drop testing and troubleshooting pressure switches
• Bluetooth / app-connected models for faster reporting and logging (model dependent)
• Micromanometer-style tools suited to more detailed airflow/pressure measurement (model dependent)

How to choose the right manometer

1. Single vs dual port: dual port is the go-to for pressure drop and switch testing.
2. Range + resolution: choose a range that matches your typical work (duct static vs low-pressure measurement).
3. Units: pick what you quote on-site (commonly Pa/kPa/mbar and/or inH₂O—varies by model).
4. Workflow: magnets, backlight, app logging and protective storage can be big time-savers on jobs.

Pair it with

• Digital manifolds (2-valve) for refrigerant-side diagnostics
• Thermometers & probes to add temperature context to pressure readings
• Anemometers and airflow hoods if you’re doing balancing work

Compliance note

Work on refrigeration and air conditioning systems that could release refrigerant requires the appropriate refrigerant handling licence. For gas work, requirements vary by state and are governed by applicable gas safety rules and standards. If you’re unsure, contact our support team and we’ll help you choose the right tool for the job.

Manometer FAQs

What’s the difference between a manometer and a micromanometer?

A micromanometer is generally aimed at finer low-pressure resolution for detailed airflow/pressure work. Always check the listed measurement range and specs.

Do I need a dual-port manometer?

If you regularly measure pressure drop across filters/coils or troubleshoot pressure switches, dual-port usually makes the job easier.

Can I use a manometer for duct static pressure?

Yes—many HVAC models are designed for static and differential pressure. Confirm the pressure range and ports match your method.

Are Bluetooth manometers worth it?

If you write reports, take before/after readings, or manage repeat maintenance, app logging can save time (model dependent).
