Digital Manifold Pressure Gauge Refrigeration Vacuum Pressure Manifold Tester Meter HVAC Temperature Tester Valve Tool KitProduct description:The handheld testo 549i smart wireless mini pressure gauge is suitable for air conditioning and refrigeration systems. It can be set up quickly and easily directly at the pressure connection point during maintenance, troubleshooting and installation. The testo 549i makes it easier to measure pressure connections at remote points. No hose is needed during measurement, reducing the loss of refrigerant caused by pipe connection. When wireless with testo 115iWhen the mini pipe clamp temperature measuring instrument is used in combination, it can also calculate the parameters of the refrigeration system. The testo Smart Probe APP provides higher measurement convenience. The measurement readings can be conveniently viewed on your terminal device through the testo Smart Probe APP. In addition, the testo Smart Probe APP can also be used to automatically calculate evaporation and condensation temperatures. All measurement data can be displayed in the form of graphs or tables. The measurement data record can be sent directly via e-mail as a PDF or Excel file.

If so, the testo 549, our entry-level digital manifold, is the perfect choice for you. This 2-way manifold can be used for 60 refrigerants and offers practical solutions for your everyday work: Two temperature-compensated pressure sensors ensure fast, precise measurement of high and low pressure, and automatic calculation of the evaporating and condensing temperatureTwo connections for external temperature probes: with temperature probes attached (optional), the digital manifold can calculate superheating and subcooling simultaneously and in real time. This means you can do away with manual comparisons, which are prone to error, and obtain fast, accurate resultsLeakage test of refrigeration systems: the manifold can carry out a temperature-compensated leakage test of the system for rough tightness testing. 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 immediatelyCan be used for standard refrigerants: the 60 most common refrigerants are stored in the instrument as standardYou 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. Digital manifold: sturdy and 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.
