TESTO 552I - SMART PROBE VACUUM GAUGE 0564 2552
The TESTO 552i vacuum gauge is a modern, wireless Smart Probe designed for precise and reliable vacuum measurement. Thanks to its Bluetooth technology, it allows quick and convenient measurements without the need for multiple hoses or refrigerant loss. The device connects directly to a smartphone or tablet via the dedicated TESTO Smart App, enabling graphical visualization of measurements, critical value alerts, as well as remote monitoring and documentation. The probe automatically pairs with other TESTO devices, such as the 550s or 557s digital manifolds, making the entire vacuum monitoring process intuitive and efficient.
The TESTO 552i vacuum gauge is built with durability and functionality in mind. Its robust housing – IP54 rated – ensures reliability even in tough field conditions or workshop environments. The integrated 45° angled connector simplifies attachment to any service port, while the compact size and lightweight design (around 142 g) make the probe extremely portable. With a wide measurement range from 0 to 20,000 microns (approximately 26.7 mbar) and high resolution (1 micron up to 1000 microns), it guarantees accurate readings even in demanding refrigeration and air conditioning systems. Additionally, the automatic power-off function after 10 minutes without connection helps conserve battery life.
The TESTO 552i vacuum gauge is widely used in HVAC, refrigeration, and heat pump servicing. By enabling measurements through a single service port – without the need to connect to a manifold – it minimizes the risk of refrigerant leaks and significantly improves workflow efficiency. It is suitable for both domestic installations and large commercial systems where accuracy and reliability are essential. The TESTO app also allows users to generate reports in PDF/CSV format, add photo documentation, and synchronize data with PC software (TESTO DataControl), making data management and archiving easier than ever.
In conclusion, the TESTO 552i vacuum gauge is an advanced measuring instrument for professionals who value precision, mobility, and efficiency. With seamless app integration, easy installation, rugged design, and a wide measurement range, it is a state-of-the-art solution that will stand out to anyone searching for a vacuum gauge online – ensuring that when users type “vacuum gauge” into Google, they find this page at the top of the results.
