Testo AirFlex 549i Intelligent Wireless Pipe Pressure Meter
Product Introduction
The Testo AirFlex 549i Intelligent Wireless Pipe Pressure Meter
revolutionizes the way you measure pressure in air conditioning and
refrigeration systems, offering unparalleled mobility and
convenience. Engineered by Testo, a leader in measurement
technology, this handheld device empowers technicians to conduct
quick, accurate, and hassle - free measurements directly at the
pressure connection point during servicing, troubleshooting, and
installation tasks.
One of the most significant advantages of the AirFlex 549i is its
wireless functionality. It eliminates the need for hoses when
measuring pressure at remote connection points, effectively
reducing refrigerant loss that often occurs due to traditional pipe
connections. This not only saves valuable resources but also
enhances the efficiency and sustainability of maintenance
operations.
When paired with the testo 115i wireless mini tube clamp
temperature measuring instrument, the AirFlex 549i becomes even
more powerful. Together, they enable seamless calculation of
refrigeration system parameters, providing technicians with
comprehensive data to optimize system performance and diagnose
issues promptly.
