Testo 549i Smart Wireless Pipe Pressure Meter

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.
