Fluke 922 Differential Manometer, Max Pressure Measurement 6 psi

This manometer is a handheld Airflow meter and micromanometer designed for HVAC and ventilation diagnostics, combining differential and static pressure, Air velocity and volume measurements in a single instrument for field use. It accepts pitot tube inputs and permits user entry of duct shape and size, enabling technicians to assess pressure relationships, balance ventilation and verify Airflow across filters and coils within normal site temperatures.

• Differential range up to 10psi with ±1% accuracy for precise readings
• Air velocity measurement to 16,000fpm allowing wide‑velocity coverage
• Airflow display to 99,999cfm for comprehensive volume reporting
• On‑board data logging storing 99 readings for later analysis
• Bright backlit LCD for visibility in poorly lit workspaces
• Four AA battery operation providing long run‑time under typical use

• Suitable for measuring pressure drops across filters and coils
• Ideal for performing duct traverses with pitot tube inputs
• Used for balancing ventilation to occupant loads
• Can be used to monitor indoor versus outdoor pressure relationships
• Suitable for verifying airflow and velocity in HVAC systems

It runs from four AA batteries

The instrument stores up to 99 readings internally for download or manual transcription when completing site reports.

Operating temperatures span 0–50°C with non‑condensing humidity up to 90% and an IP40 ingress rating for routine indoor field conditions.

It uses differential pressure ports and each port accepts pressures up to 10psi maximum to protect sensors during testing.

2 x Rubber hoses, wrist strap, carrying case, operation manual, 4 x AA Alkaline batteries
