Refrigeration Pressure Gauge – Testo 549

Introducing the testo 549 refrigeration pressure gauge

Great application of testo 549

Two temperature compensated pressure sensors ensure fast, accurate measurements, and automatically calculates evaporation and condensation temperatures

Two connections for external temperature probes (order option): testo 549 can calculate heating and cooling in real time. This helps you eliminate manual, error-prone comparisons and get quick, accurate results.

Check for leaks in the refrigeration system: testo 549 can perform temperature compensated leak testing. With this feature the initial system pressure is compared with the system pressure at the end of the measurement, so the difference (if any) can be displayed immediately.

Can be used for standard refrigerants: 60 of the most common refrigerants are stored in the device as standard

testo 549 digital refrigeration pressure gauge: rugged and practical

The testo 549 has a robust 2-way valve block made of metal with 3 connections, 3 tube holders, is easy to handle and can even withstand harsh environmental conditions. With a sturdy case, the device can be reliably protected against external influences according to protection class IP42. You can use the hanger to secure the testo 549 during measurements. Thanks to the built-in backlight, you can read the results easily, even in low light environments.
