Testo 549i Smart Wireless Pipe Pressure Meter
Product Introduction
The Testo 549i is an intelligent wireless pressure meter designed
for air conditioning and refrigeration systems, offering
unparalleled mobility and convenience during servicing,
troubleshooting, and installation. This handheld device eliminates
the need for hoses by connecting directly to pressure points,
reducing refrigerant loss and streamlining measurements at remote
locations. With a 100m radio range, it enables real-time data
transmission to compatible devices, while its compact design
(125×32×31mm, 156.6g) ensures easy handling in tight spaces. When
paired with the testo 115i wireless temperature clamp, it
calculates key refrigeration system parameters for comprehensive
diagnostics.
