testo 552 - Digital vacuum gauge with Bluetooth®

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 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. Key benefits: • Measurement data monitoring via testo Smart App • Measurement data dispatch via testo Smart App • Extremely precise, extremely rugged, extremely practical – with visual alarm and backlit display • Measures pressure and calculates the evaporation temperature of H2O automatically The testo Smart Probes App turns your mobile device into a remote control and measurement data centre. Install our testo Smart Probes App on your smartphone/tablet and take advantage of these practical features: • Wireless control and monitoring of the Smart Probes via smartphone/ tablet • Record and send measurement trends via App as an Excel file (csv.) • Create and send .pdf reports, including pictures of the measuring location • Display readings from up to 6 Smart Probes simultaneously • Range of approx. 15 m in free field (depending on the mobile device used) • Diagram display can be dynamically zoomed in or out Application-specific measurement menus provide optimum support for your measurement: • Refrigeration: Automatic calculation of system parameters, such as superheating or subcooling • Air flow measurements in ducts/at outlets: Simple parameterization and implementation of multi-point and timed measurements • IR temperature and mould indication: Non-contact temperature measurement with quick image documentation, including measurement spot marking and detection of areas susceptible to mould Control and read complete measurement via smartphone Scope of delivery: testo 552 digital vacuum gauge with Bluetooth®, two AA batteries.
