Meter App

About this app

The SmarTech Fusion app is built for HVAC professionals who need fast, accurate, and connected system diagnostics in the field. Designed to work
seamlessly with SmarTech Fusion wireless tools, the app delivers real-time system data directly to your mobile device, helping you troubleshoot, verify, and document performance with confidence.
Connect to a full range of wireless instruments including pressure gauges,
temperature clamps, psychrometer probes, manometer probes, vacuum gauge, ambient temperature probe, and Bluetooth scale. Monitor live pressure, temperature, vacuum, and weight readings while performing service, installation, or maintenance tasks.

The app supports complete system diagnostics on both the refrigerant and air side. Perform refrigerant-side analysis with automatic superheat and subcooling calculations. Run nitrogen pressure tests for leak detection and execute vacuum tests, including evacuation and vacuum rise verification. On
the air side, measure return and supply conditions with dry bulb and wet bulb
readings, along with calculated enthalpy, dew point, and relative humidity.

SmarTech Fusion also enables static pressure measurements and system
performance analysis, giving technicians a full picture of system operation in one place. The intuitive interface allows for quick setup, reliable wireless
connectivity, and easy navigation between tools and measurements. Generate detailed service reports directly from the app, including system data and optional photos. Export reports as PDFs to share with customers, document job performance, or maintain service records. This streamlines workflow and adds professionalism to every job.

Whether you're commissioning new systems, performing maintenance, or
diagnosing issues, SmarTech Fusion brings all your measurements, calculations, and reporting into a single, efficient platform—helping you work smarter and complete jobs faster.
