Testo 549 Digital Manifold for HVAC Pressure Measurement

The Testo 549 Digital Manifold revolutionizes pressure measurement for refrigeration and air conditioning systems, replacing analog gauges with precise digital technology. This rugged instrument stores 60 refrigerant profiles, measures high-side and low-side pressures, and instantly displays corresponding saturation and evaporation temperatures. When paired with optional temperature probes, it provides real-time superheat and sub-cooling calculations at the push of a button.
