For this, the initial system pressure is compared with the system pressure at the end of the measurement, so that the difference (if there is one) can be displayed immediately. Can be used for standard refrigerants: the 60 most common refrigera. Nts are stored in the instrument as standard. You can also view the temperature difference via the 2-way manifold. The automatic heat pump mode, which makes switching over the refrigerant hoses unnecessary, is also really practical.
The testo 549 digital manifold features a robust 2-way valve block made of metal with 3 connections and 3 hose holders, is easy to handle and can even withstand harsh environmental conditions. With its solid housing, the instrument is reliably protected against impacts in compliance with protection class IP 42. You can use the suspension hook to secure the manifold during the measuring process.Thanks to the illuminated display, you can read off the readings easily, even in dark environments. The battery is not included in the package for transportation reasons. 250h(without illumination, without Bluetooth). 60Profiles:R11;R12;R123;R1234yf;R1234ze;R125;R12B1;R134a;R14;R142B.
