The testo 549 digital manifold aids in carrying out maintenance or installation work on refrigeration systems and heat pumps. With its integrated temperature measurement and automatic calculation of superheating/subcooling, you can now do away with additional measurements and manual comparisons (when using an optional clamp probe).

  1. Calculation of superheating/subcooling in real time with up to two external temperature probes
  2. 2-way valve block with three connections, three hose parkers and sight glass
  3. 60 common refrigerants stored in the instrument
  4. Display illumination for better legibility in dark surroundings
  5. 250 hours‘ battery life


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. 
 
Digital manifold: sturdy and practical  
 
The testo 549 digital manifold features a robust 2-way valve block made of metal with 3 connections and 3 hose holders, is easy to handle and can even withstand harsh environmental conditions. With its solid housing, the instrument is reliably protected against impacts in compliance with protection class IP 42. You can use the suspension hook to secure the manifold during the measuring process. Thanks to the illuminated display, you can read off the readings easily, even in dark environments.

Refrigeration Manifold - testo 570-1
Model No: testo 570-1 Part No: 0563 5701

The testo 570-1 digital manifold is ideal for all measurement tasks on refrigeration systems and heat pumps like measuring, analyzing and logging– pressure, temperature, electricity and vacuum measurements.

  1. Calculate superheating and subcooling simultaneously
  2. Record pressure, temperature, current and vacuum measurement in one instrument
  3. 999 hours recording measurement values
  4. 40 refrigerants stored
  5. Report printout on site with Testo fast printer


For refrigeration systems and heat pumps to function smoothly and efficiently, the pressure, temperatures and any system superheating or subcooling need to be monitored. The testo 570-1 refrigeration manifold can record or calculate all these values and also enable temperature-compensated tightness testing. Which is why our 4-way refrigeration manifold supplies you with the key information that you need for the optimum commissioning and maintenance of refrigeration systems or for error diagnosis. Complex manual comparisons and calculations (e.g. of superheating and subcooling), which would be necessary when using analog manifolds, are not needed. 
 
Thanks to digital technology, several manual steps and calculations are no longer required  
 -  Record readings over a period of up to 999 hours:  the results are safely stored in the instrument, even for long-term measurements on refrigeration systems or heat          pumps 
 -  Real-time recording and graphic presentation of measurement data:  as an option you can purchase the “EasyKool” software, which can be used to clearly present the      measurement data. This is particularly useful for identifying sources of error in the event of a fault, and taking countermeasures if needed 
 -  Protocol access and printout:  the testo fast printer, which is available as an option, enables on-site printout of measurement data. You can also view the measurement      protocols in the “EasyKool” software (optional) 
 -  Suitable for all common refrigerants:  40 current refrigerants are stored in the manifold and can be updated if necessary using the optional “EasyKool” software 
 -  Pressure measurement with automatic temperature calculation:  high and low pressure is measured via two temperature-compensated pressure sensors, which                  automatically calculate the temperatures in addition 
 -  Three connections for external temperature probes:  connect up to three temperature probes (optional) in order to calculate superheating and subcooling in parallel and      record the ambient temperature (e.g. in cold storage rooms) 
 -  Integrated vacuum measurement:  when evacuating refrigeration systems, you can use the 4-way manifold to carry out vacuum measurements. The integrated vacuum      sensor enables precise vacuum measurements 
 -  Automatic heat pump mode:  saves you from having to change refrigerant hoses 
 -  Other features  such as temperature-compensated tightness testing and automatic ambient pressure compensation are included in the refrigeration manifold 

Together with the testo 570-1 refrigeration manifold, you also get a clamp temperature probe. Simply clamped to the pipe, this reliably measures the surface temperature. Our probes range also includes attachable probes for measuring temperature, current or oil pressure. 

Robust and convenient – the refrigeration manifold works like a pro  
The testo 570-1 refrigeration manifold is suitable for practical use, largely thanks to its robust 4-way valve block with 4 connections, 4 hose parkers and its inspection glass. Maintenance and servicing tasks on refrigeration systems and heat pumps are made easier due to the manageability of the instrument. 
With its solid housing, the refrigeration manifold is protected against impacts. A suspension hook on the back secures the instrument during the measurement. In addition, the manifold has a large, illuminated display, so you will have no problem reading off the readings, even in a dark environment. 
Recommendation: if you would like to have a key accessory to hand, you can purchase the refrigeration manifold testo 570-2 Set. This manifold set contains a second clamp temperature probe, the “EasyKool” software, a USB cable, a mains unit and a transport case.
