Testo 552 Digital Vacuum Gauge
The Testo 552 Digital Vacuum Gauge delivers highly accurate measurements for vacuum conditions in refrigeration and heat pump systems. Designed for service and maintenance professionals, it helps verify the full dehumidification of a system by identifying the presence of unwanted gases and oils. Built for precision and reliability, this device ensures accurate results every time without the need for sensor servicing.
With Bluetooth connectivity, the Testo 552 easily links to the Testo Smart Probes App on a compatible smartphone. This allows users to view data remotely and track pressure readings in real time, saving time and effort on site. The device also features a detailed, backlit display that enhances visibility in dim environments.
Reliable Performance in All Conditions
The integrated absolute pressure sensor is designed to operate maintenance-free. It measures vacuum ranges from 0 to 20,000 microns and includes overload protection for safety. With a 50-hour battery life powered by just two AA batteries, engineers can work for extended periods without interruption.
Practical Design for Everyday Use
Built for on-site use, the Testo 552 includes a fold-out hook for easy suspension during use. The optical alarm alerts users when limits are exceeded, while the Mini-DIN connector provides a direct link to the Testo 570 digital manifold. Rugged, dirt- and water-tested construction ensures the device stands up to demanding fieldwork.
