- Determination of high and low pressure, automatic determination of condensation and evaporation temperature and calculation of superheating/subcooling. All the results can be read simultaneously on one display (in conjunction with the appropriate Testo Smart Probes)
- Tightness test: Recording and analysis of the pressure curve
- Automatic calculation of the target superheat (in conjunction with the testo Smart App and the appropriate Testo Smart Probes, e.g. testo 115i and testo 605i)
- Evacuation: Graphic progression display of the measurement with indication of the start and differential value (in conjunction with the appropriate Testo Smart Probe, e.g. testo 552i vacuum probe)
Complying with manufacturer's specifications
Some manufacturers specify exactly what the absolute pressure must be for you to evacuate your air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552.
Connect to the testo 570 Digital Manifold
When you connect the testo 552 Digital Vacuum Gauge to the testo 570 Digital Manifold, you can save the testo 552's readings directly on a laptop via the optional EasyKool software. This allows data-logging and/or on-site printing.
Complying with manufacturer's specifications
Some manufacturers specify the desired micron lower limit that must be achieved to evacuate their air conditioning systems and how long this pressure must be maintained. Compliance with these specifications is simple and easy thanks to the flexible setting of the alarm threshold in the testo 552.
Evacuating AC/R systems
The testo 552 Digital Vacuum Gauge is for the evacuation of heat pumps, air conditioning, and refrigeration systems. The innovative testo 552 utilizes a sensor that, unlike the competition, requires no cleaning and is not affected by contamination. Never worry about a dirty sensor causing false readings. Trust your testo 552 to always be accurate.
