  • 1. Measurement Solutions forRefrigeration Technology.Digital manifold, leak detection, vacuum measurement, and lots more.
  • 2. Testo refrigeration technologyDigital is better:Refrigeration technology expertise fromTesto.Complete solution for the commissioning and maintenance of refrigeration systems andheat pumps.There are many different tasks involved in refrigeration You can avoid these problems by using digital manifoldssystem construction. These range from project planning and from Testo. One instrument records a wide range ofinstallation, through to the maintenance of refrigeration and parameters: they can measure pressure and temperatureair conditioning systems or heat pumps. values quickly and easily, or carry out temperature- compensated tightness testing. Data can be stored andFor a system to function as planned, pressure, temperatures evaluated on the PC and measurement protocols can beand any system superheating or subcooling need to be printed out directly on site.

This instrument can measure extremely smallmeasurement results all lead to systems being configured pressures in the vacuum range with the greatestinefficiently and extra costs for your customers. of accuracy, providing you with information on the dehumidification status. The testo 552s maintenance-free absolute pressure sensor is unique and provides you with measurement results that are permanently reliable, with no sensor cleaning required.2

Its robust construction makes it ideal for everyday use, protected against dirt and water.testo 552 is the only digital vacuum gauge whose absolutepressure sensor needs no further servicing, unlike othersensor technologies. Suspension device Fold-out robust hook, making it easy to attach the testo 552 to pipelines, for example. MiniDin connector MiniDin connector for connection to the testo 570 digital manifold via connecting cable (0554 5520). Battery level display testo 552 is supplied with two standard AA batteries with a life of up to 2,400 hours (100 days continuous operation). Temperatures Evaporation temperature of water (H2O), ambient temperature and the temperature difference DeltaT are displayed. Absolute pressure Clear display of the absolute pressure value measured. Display illumination Makes it easy to read off the data, even in dark surroundings.4
  • 5. To save, print out or document measurement data electronically, the testo 552 can be connected to the testo 570 with a connecting cable. Long-termmeasurements can even be processed over several days without a problem.Technical data for testo 552Vacuum measuring range 1100 - 0 mbar / 825080 - 0 micronSensor overload absolute: 6 bar / 87 psi (relative: 5 bar / 72 psi)Vacuum resolution 0.01 hPa / 10 micronVacuum precision 0 to 1.33 hPa / 0 to 1000 micron: up to ±10 micron 0 to 200 hPa / 0 to 150000 micron: ± 0.3% FS = ±0.6 hPA 200 to 1100 hPa / 150000 to 825080 micron: ±0.3% FS = ±3.3 hPaOperating temperature -20 to 50 °C / -4 to 122 °FBattery life 2,400 h (2x AA), (approx. 130 h with background illumination activated)Protection class IP 42Parameter mmHg, Torr, mbar, hPa, micron, inH20, inHg, PaMeasuring cycle 0.5 secSensors 1 x absolute pressure sensorConnections - 2x 7/16“ UNF - 1x MiniDin (testo 570) 5
  • 6. testo 550, testo 557, testo 570Measure digitally, work efficiently.Test refrigeration systems quickly and safely using digital manifolds. These days, many spheres of life would be unthin- kable without digital technology. The refrigeration industry is no exception. Yet analogue manifolds are still widely in use in refrigeration technology. Accor- ding to numerous studies, among others conducted by the US government organisation “Energy Star”, up to 74% of all refrigeration systems are incorrectly configured using analogue measuring technology.* It is inaccurate, inconvenient to handle, and requires the user to interpret the measurement results. Digital manifolds from Testo can accommodate all the day-to-day requirements of the refrigeration industry. They can measure a variety of operating parameters using just one instrument. Get a comprehensive overview of the condition of a refrigeration system or heat pump in real time, whenever you need it. Reliable measurement results, leading to efficiently-configured refrigeration systems, can actually save up to 12.5% of energy costs.* *Source: www.energystar.gov6

If your aim is to maintain the professionally.”operational reliability of systems and at the sametime reduce CO2 emissions, then you need digitalmeasurement technology.” Florian Endres, Product Manager, Testo AG Andreas Dahms, Engineer Engineering Office for Refrigera- tion, Air Conditioning and Heat “Since we introduced digital manifolds, our staff Pump Technology measure far more efficiently. Not only in terms of accuracy, but also in terms of the time needed to adjust a system.” Thomas Starke, Purchasing Ma- nager, Dresdner Kühlanlagenbau GmbH 7 7
