Digital Manifolds
Testo
Advanced digital manifolds featuring Bluetooth connectivity and smart measurement menus - delivering comprehensive HVAC system diagnostics with automatic calculations and documentation.
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.
Why Choose Testo Manifolds
Testo digital manifolds are engineered in Germany with precision sensors and robust construction for professional HVAC/R applications. The wireless temperature probe system eliminates thermocouple wire runs, and the integrated refrigerant database ensures accurate calculations across all common refrigerant types. For service teams using measureQuick, Testo manifolds provide a reliable platform for standardized refrigerant diagnostics with automated reporting and cloud-based documentation.
