Testo 549 Digital Manifold
Product Introduction
The Testo 549 Digital Manifold is a revolutionary instrument that renders analog gauges outdated, offering precise and efficient pressure measurement for refrigeration and air conditioning systems. With its ability to store 60 refrigerant profiles, it quickly measures high-side and low-side pressures and instantly displays the corresponding saturation and evaporation temperatures, making it a versatile tool for technicians. Its rugged design ensures long-term reliable service, and when paired with optional temperature probes, it provides real-time superheat and sub-cooling calculations at the push of a button.
Features
Precise Pressure Measurement: Accurately measures high-side and low-side pressures, with instant display of saturation and evaporation temperatures for 60 stored refrigerants.
60 Refrigerant Profiles: On-board storage of 60 refrigerant profiles eliminates the need for multiple gauges, making it a one-stop solution for various systems.
Optional Superheat/Sub-cooling Calculation: When equipped with optional temperature probes, it provides real-time superheat and sub-cooling values, simplifying system diagnostics.
2-way Valve Block: Features a 2-way valve block with three connections and a sight glass, facilitating easy connection and observation.
Large Backlit Display: A large 2-line backlit display ensures clear reading of measurements even in low-light environments.
