This 510i differential pressure measuring instrument from Testo can be used in conjunction with a smartphone or tablet for quick and easy measurement of air and gas flow pressure and static pressure, as well as pressure drops on fans and filters.
You can also use the compact Testo 510i for flow measurement and volume flow measurement. Using your smartphone or tablet as a display, the Testo Smart Probes App allows you to view readings conveniently, configure volume flow measurements quickly and easily, and carry out reliable timed and multi-point mean calculation.
The App also includes a measurement menu for the pressure drop test. All measurement data can be displayed as a chart or in table form. The measurement data log can be emailed directly as a PDF or Excel file.
The Testo 549i high-pressure measuring instrument is suitable for carrying out wireless installation, servicing and troubleshooting on air conditioning and refrigeration systems. It makes working on widely spaced pressure connections considerably easier thanks to wireless connection to a smartphone or tablet.
As no hoses are required for measurements, little or no refrigerant is lost. Readings can be viewed conveniently on your smartphone or tablet device via the Testo Smart Probes App. The App also enables evaporation and condensation temperatures to be calculated automatically. All measurement data is displayed either as a chart or in table form. The measurement data log can be emailed directly as a PDF or Excel file.

The Testo 552 is a digital vacuum measuring instrument, ideal for use during the evacuation of refrigeration systems and heat pumps. It measures even the smallest absolute pressures and provides highly precise information on the status of the dehumidification of a system. Its robust construction makes it suitable for daily use, and protects it from dirt and water.
This version of the Testo 552 connects via Bluetooth with the Testo Smart Probes App on your smartphone or tablet, allowing you to monitor the absolute pressure reached during evacuation. Measurement results are documented in the App and sent by e-mail report.
Absolute pressure measuring range: 0 to 0.40psi/ 0 to 26.66mbar/0 to 20000micron
Accuracy: ±(10micron + 10% of mv) (100 to 1000micron)
Operating temperature: -10 to +50°C
Protection class: IP42
System requirements: iOS 8.3 or newer, Android 4.3 or newer, mobile device with Bluetooth 4.0
Heating installers and air conditioning engineers will be well-equipped with this 510 differential pressure measuring instrument from Testo. The instrument measures differential pressure from 0 to 100mbar and can help you check filters on air conditioning systems or measure static gas and gas flow pressure on heating systems, for example.
The differential pressure measurement has temperature and air density compensation for accurate readings and is small, handy and easy to operate with just three buttons. You can work with your hands free thanks to magnets on the rear of the instrument. When there is poor visibility, such as in dark surroundings, the illuminated display makes it easier to work.
The belt pouch and plug-on protective cap mean the instrument can be safely stowed away and well-secured during measurement thanks to a wrist strap.
Differential pressure sensor - Piezo-resistive
Measuring range: 0 to 100mbar
Accuracy: ±0.03mbar (0 to 0.30mbar) ±0.05mbar (0.31 to 1.00mbar), ±(0.1mbar + 1.5% of mv) (1.01 to 100mbar)
