Testo digital manifolds combine precision pressure measurement with wireless temperature probes for comprehensive HVAC/R refrigerant diagnostics. Models including the Testo 557s and 550s series feature Bluetooth connectivity to measureQuick, enabling automated superheat and subcooling calculations with real-time system performance analysis.

Testo Digital Manifold Features

Testo digital manifolds feature high-resolution pressure sensors, backlit displays, and integrated refrigerant databases covering all common refrigerant types including newer A2L blends. The manifolds connect to wireless temperature clamps for automated superheat and subcooling calculations directly on the instrument display. Valve configurations range from 2-way to 4-way models, with dedicated vacuum ports on select models for faster evacuation.

measureQuick Integration for Refrigerant Diagnostics

When connected to measureQuick via Bluetooth, Testo digital manifolds stream live pressure and temperature data for real-time refrigerant-side analysis. measureQuick displays superheat, subcooling, approach temperatures, and system efficiency metrics alongside the manifold data, providing a comprehensive view of system performance. This integration is particularly valuable for documenting refrigerant charge verification and identifying system faults during maintenance visits.
