  • Description

    Testo 552 Digital Vacuum Instrument

    The Testo 552 Digital Vacuum instrument is one of Testo’s latest additions to its extensive, accurate product range. This particular device specialises in measuring precise pressures and providing detailed information and status on the dehumidification of a system. (Dehumidification often relates to the removal of foreign substances including gases, oils) This evacuation is an important procedure that often takes place on refrigeration systems or heat pumps during service and maintenance.

    Testo 552 Digital Vacuum Gauge Features

    • Backlist display – Beneficial in dark environments
    • Fold out hook suspension – Highly functional for attaching the meter to piplines etc
    • MiniDin Connector – Simple connection to the Testo 570 Digital Manifold
    • 2400 Hour Battery Life
    • Detailed Display – Shows Evaporation temperature, ambient temperature and temperature differences
    • Highly accurate maintenance free pressure sensor
    • Optical alarm -  Useful for exceeded value limits

    Traditionally analogue manifolds have been used to measure refrigeration systems. Naturally analogue meters offer a lower level of accuracy and are at times inconvenient to handle. With the Testo 552 being centred on digital technology you can measure with complete accuracy and complete peace of mind. Remove the need to interpret measurement results with a full digital read out on a large backlit display.

    Another fantastic benefit for engineers undertaking evacuation on a system is that the Testo 552’s absolute pressure sensor never has to be serviced or replaced. Testo have ensured accurate measurements are not compromised and have also developed a system with 2400 hours of life from just two conventional AA batteries. This equates to around 100 days testing before needing to recharge.  

    As with all the Testo range the 552 incorporates a robust construction designed for daily use and has been tested against water and dirt.

    Ensure all future heat pump and refrigeration systems are correctly configured with the latest accurate technology available from the Testo 552 Digital Vacuum Gauge.
