testo 549 Entry-Level Digital Manifold for Refrigeration Systems
Product Introduction
The testo 549 digital manifold revolutionizes refrigeration system
maintenance by replacing cumbersome analog gauges with intelligent
digital technology. Designed for entry-level users, it supports 60
common refrigerants and integrates temperature measurement with
automatic superheating/subcooling calculations, eliminating manual
errors. With dual pressure sensors and external probe connections,
this 2-way manifold streamlines diagnostics for refrigeration
systems and heat pumps, combining accuracy with user-friendly
operation.
Product Features
- Comprehensive Measurement Capabilities:
- Pressure Sensing: Dual temperature-compensated sensors for high/low
pressure readings, with automatic calculation of
evaporating/condensing temperatures.
- Temperature Range: -50 to 150°C with ±0.5°C accuracy and 0.1°C
resolution.
- Superheating/Subcooling: Calculates in real time when paired with
optional clamp probes (2 x NTC plug-in connections).
- Refrigerant Versatility:
- Pre-programmed with 60 standard refrigerants, suitable for most
commercial and residential systems.
- Leakage Testing:
- Performs temperature-compensated leakage tests by comparing initial
and final system pressures, displaying differences instantly.
- Heat Pump Mode:
- Automatic switching eliminates the need to reposition refrigerant
hoses, enhancing efficiency during heat pump diagnostics.
- Portable & Durable Design:
- Weighs 1060g for handheld use, with a rugged build for field
reliability.
