The Testo 552 is a digital vacuum measuring instrument, ideal for use during the evacuation of refrigeration systems and heat pumps. It measures even the smallest absolute pressures and provides highly precise information on the status of the dehumidification of a system. Its robust construction makes it suitable for daily use, and protects it from dirt and water.
