testo 549 – Digital manifold

Product Descriptions
When carrying out maintenance or installation work on refrigeration systems and heat pumps, are you increasingly noticing that the use of analog manifolds is laborious and time-consuming? If so, the testo 549, our entry-level digital manifold, is the perfect choice for you. This 2-way manifold can be used for 60 refrigerants and offers practical solutions for your everyday work:
Two temperature-compensated pressure sensors ensure fast, precise measurement of high and low pressure, and automatic calculation of the evaporating and condensing temperature
Two connections for external temperature probes: with temperature probes attached (optional), the digital manifold can calculate superheating and subcooling simultaneously and in real time. This means you can do away with manual comparisons, which are prone to error, and obtain fast, accurate results
Leakage test of refrigeration systems: the manifold can carry out a temperature-compensated leakage test of the system for rough tightness testing. For this, the initial system pressure is compared with the system pressure at the end of the measurement, so that the difference (if there is one) can be displayed immediately
Can be used for standard refrigerants: the 60 most common refrigerants are stored in the instrument as standard
You can also view the temperature difference via the 2-way manifold. The automatic heat pump mode, which makes switching over the refrigerant hoses unnecessary, is also really practical.
• Calculation of superheating/subcooling in real time with up to two external temperature probes
• 2-way valve block with three connections, three hose parkers and sight glass
• 60 common refrigerants stored in the instrumentIdeal for tough applications thanks to impact protection and IP65
• Display illumination for better legibility in dark surroundings
• 250 hours‘ battery life
