Testo 549i Refrigeration Smart Pressure Probe

Overview

Testo offers you greater mobility when measuring: used in conjunction with your smartphone or tablet, the handy Testo 549i high-pressure Smart Probe lets refrigeration and air-conditioning technicians measure refrigerant pressures without being tied to a fixed manifold. It attaches directly to the service port and sends readings wirelessly to the testo Smart App.

The 549i measures pressure from -1 to +60 bar with 0.5% full-scale accuracy and works with all common refrigerants (CFC, HFC, HCFC, N₂, H₂O and CO₂). In the app you can display high and low pressure, calculate evaporating and condensing temperature, and determine superheat and subcooling when combined with testo 115i clamp probes, making system diagnosis quick and flexible.
