Testo 549 Digital Refrigeration Manifold with Temperature Measurement

The testo 549 Entry-Level Digital Refrigeration Manifold is a user-friendly, efficient tool designed to simplify maintenance and installation work on refrigeration systems and heat pumps. As an upgrade from analog manifolds, it integrates temperature measurement and automatic calculations of superheating and subcooling (with an optional clamp probe), eliminating the need for additional manual measurements and comparisons. Compatible with 60 common refrigerants, it streamlines daily tasks for technicians, offering precision and convenience in a rugged, easy-to-handle design.

• Supports 60 commonly used refrigerants, pre-stored in the instrument for immediate access to standard applications.
• Automatic calculation of superheating and subcooling in real time (when paired with optional external temperature probes), reducing manual errors and saving time.
• Two temperature-compensated pressure sensors for fast, precise high and low pressure measurements, with automatic calculation of evaporating and condensing temperatures.
• Temperature-compensated leakage test function, comparing initial and final system pressures to quickly identify leaks during rough tightness testing.
• Robust 2-way metal valve block with 3 connections and 3 hose holders, ensuring durability in harsh working conditions.
• Practical heat pump mode that eliminates the need to switch refrigerant hoses, enhancing operational efficiency.
• IP 42 protection class and solid housing, providing reliable resistance to impacts and environmental hazards.
• Illuminated display for easy reading in dark environments, paired with a suspension hook for secure placement during measurements.
