The TPI SP620 Smart Probe differential pressure meter is a professional-grade wireless measurement tool designed for HVAC, boiler, combustion testing and ventilation system diagnostics. As part of the Smart Probe family, this compact differential pressure meter connects via Bluetooth to the TPI Smart Probes app on a smartphone or tablet, enabling real-time readings, data logging, graphing and report generation without the need for a separate display unit. Engineered for everyday trade use, it provides accurate differential pressure readings that help engineers assess air-flow balance, filter condition, fan performance, flue draft and system pressures during commissioning, servicing and fault-finding tasks.

This smart differential pressure meter is compatible with standard pressure tubing and fittings used in pressurised hydronic, HVAC and combustion applications. Because it delivers wireless convenience with robust measurement performance, it is ideal for busy heating, ventilation and service professionals who need quick, accurate differential pressure data without trailing cables or bulky instruments.

Key features of the TPI SP620 Smart Probe differential pressure meter include true Bluetooth connectivity to mobile devices for intuitive on-screen measurement and recording, precise differential pressure measurement suitable for HVAC, boiler and flue testing, compact and rugged construction for reliable field performance, integration with the TPI Smart Probes app for data logging, trend analysis and reporting, and practical utility when used by qualified engineers and technicians to support system diagnostics, airflow balancing and commissioning.
