Data Storage & Zero Out

Supports 100 groups measurement data storage and zero adjust to zero out remaining data feature. One-click “HOLD” to freeze measurement data, “UNITS” button to switch different measurement units, “DIF” button to get gas differential pressure value.

Packing List:

 

 

 

  • 2x Soft Tubes
  • 1x hose adapter
  • 1x digital manometer
  • 1x instruction Manual

Two input ports - based on a dual port design, one for positive pressure testing and one for negative pressure testing, using these two ports together makes it easy to determine the air pressure differential. The air pressure tester comes with two 4mm diameter hoses and a standard 1/8" hose adapter and is suitable for testing and replacing gas valves on natural gas furnaces, diagnosing instantaneous water heaters, and measuring static pressure in piping, etc.

Zeroing - "Zeroing" function is supported to clear remaining data and ensure accurate gas pressure readings are obtained. An essential tool for any HVAC technician checking airflow pressure, static pressure or pressure switches when installing and maintaining commercial air conditioning systems.
