Description Testo 552 Digital Vacuum Measuring Gauge The Testo 552 (part# 0560-5522) is a high accuracy, high resolution digital vacuum measuring instrument. In fact, the 552 is the most accurate HVACR vacuum gauge available for servicing heat pumps and refrigeration systems. Most vacuum gauges make use of thermistor technology to make their measurements, but thermistor measurement is very much subject to its environment. The Testo 552 uses an absolute pressure sensor, isolated from contaminating oils and refrigerants. This ensures accuracy regardless of contaminants, and even allows the instrument to be used in cold exterior conditions, down to 14 °F.

The Testo 552 features a robust rubberized housing that provides non-slip handling,
