Testo 549 Entry-Level Digital Manifold

Overview

The Testo 549 is a compact, entry-level digital manifold designed for refrigeration and air-conditioning technicians. Two temperature-compensated pressure sensors ensure fast, precise measurement of high and low pressure, and automatically calculate the evaporating and condensing temperature, taking the guesswork out of everyday service work.

Two connections for external temperature probes allow superheat and subcooling to be determined directly, and the large, backlit display keeps readings clear on site. With a robust design, refrigerant database and 7/16″ UNF connections, the testo 549 is a reliable, affordable digital replacement for analogue manifold gauges.
