Digital Vacuum Gauge
Delivery Scope
testo 552 digital vacuum gauge with Bluetooth®, two AA batteries.
Testo 552 is a high-precision digital vacuum gauge is ideal for evacuating refrigerant systems or heat pumps.
- Highly accurate and reliable measurement results
- Measurement data monitoring via testo Smart Probes App
- Measurement data dispatch via testo Smart Probes App
- Measurement of the evaporation temperature of H2O
- Optical alarm when a limit value is exceeded
- Extremely robust and water/dirt resistant (IP 42)
The testo 552 is a high-precision digital vacuum gauge designed to provide you with absolutely reliable readings. It has all the measuring functions you need for evacuating refrigerant systems and heat pumps and is built to last and tough enough to take the odd knock.
Via a Bluetooth interface, the testo 552 connects with the testo Smart Probes App on your smartphone or tablet. This allows you to monitor the absolute pressure reached during the evacuation conveniently and wirelessly. In addition to this, the measurement results can be quickly documented in the App and sent by e-mail.
The testo 552 digital vacuum gauge – areas of application Evacuating is one of the most important steps when it comes to installing or restarting refrigerant or air conditioning systems: foreign gases, moisture and oils have to be removed properly. That’s when the absolute pressure of a system needs to be measured.
And that’s exactly what the testo 552 digital vacuum gauge is designed to do: the meter provides you with highly accurate information regarding the dehumidification status of the system and is able to measure even the smallest of absolute pressures absolutely reliably. This means that you are always able to observe manufacturer specifications. A visual alarm warns immediately when a threshold has been exceeded.
And because the digital vacuum gauge is IP42 rated (water resistant and dirt proof), it is virtually impervious to moisture and dirt.
