Product Description

Testo 549 Digital Manifold for Refrigeration Systems

Product Introduction

The Testo 549 digital manifold is a professional-grade tool designed to replace analog gauges, offering precise pressure measurement and intelligent temperature calculations for 60+ refrigerants. With a rugged build and user-friendly interface, it measures high/low side pressures and instantly displays saturation/evaporation temperatures. When paired with optional temperature probes, it enables automatic superheat/subcooling calculations, making it an essential device for HVAC/R technicians.
