Description
testo 549i Portable High-Pressure Gauge
Testo offers maximum mobility for measurements: when used in conjunction with a smartphone or tablet, the portable high-pressure gauge testo 549i is used for commissioning, servicing, and diagnosing air conditioning and refrigeration systems.
You won’t need a single wire to operate it. The instrument is quickly and easily installed directly onto the pressure port. The testo 549i significantly simplifies work with remote measuring points, as all measured values are transmitted to your smartphone or tablet via a wireless connection.
Key Working Advantages
- The hoseless connection of the instrument to the system ensures minimal refrigerant loss.
- When used simultaneously with the pipe clamp thermometer (clamp) testo 115i, calculation of individual refrigeration parameters is also possible.
- Recommendation: use the testo 549i as a probe in combination with a Testo multifunction instrument.
Measurement Convenience Thanks to the testo Smart Probes Mobile App
- You can view the measurement data on your smartphone or tablet.
- The App includes a function for automatic calculation of evaporation and condensation temperatures.
- All measurement data is displayed on the screen in the form of a table or graph.
- The measurement report can be sent via email in PDF or Excel format.
