Testo 549i Gen.2 HP transducer 0560 2549 02

pr0v0 — Wed, 12 Feb 2020 04:54:00 +0000

Product Description

Testo offers you greater mobility when measuring: used in conjunction with your smartphone or tablet, the handy testo 549i high-pressure gauge is suitable for carrying out wireless servicing and troubleshooting on air conditioning and refrigeration systems, as well as for installing them. The measuring instrument can be quickly and easily attached directly to the pressure connection. The testo 549i makes it considerably easier to work on pressure connections that are a long distance apart, thanks to wireless connection to a smartphone or tablet.Also practical: since no hoses are needed for the measurements, no refrigerant is lost, or only a very small quantity. When used in conjunction with the testo 115i clamp thermometer, individual refrigeration system parameters can also be calculated.

More measuring convenience thanks to the App

Readings can be viewed conveniently on your terminal device via the testo Smart Probes App. In addition, the App enables automatic calculation of evaporation and condensation temperatures. All measurement data are presented either as a diagram or a table. Finally, the measurement data report can be e-mailed directly as a pdf or Excel file.

*Our tip: Use the testo 549i as a probe in conjunction with the appropriate IAQ measuring instrument from Testo.

Delivery Scope

1 x testo 549i high-pressure gauge operated via smartphone, including batteries and calibration protocol.

Testo 410i Vane Anemometer

pr0v0 — Thu, 11 Feb 2016 03:47:22 +0000

It fits perfectly into any shirt pocket: the testo 410i vane anemometer is ideal for measuring air velocity and temperature at air outlets and ventilation grilles. Even measuring and adjusting the volume flow is easy. The testo 410i gives you huge flexibility, so you can adapt to any unplanned measuring requirements in your everyday work.

Measuring convenience thanks to the App

The testo 410i combines professional Testo measuring technology with the efficient functions of an App. Your smartphone or tablet is used as a convenient display for your measuring values on site. You can view all measurement data via the testo Smart Tools App, and email the log immediately as a PDF or Excel file.

Configuration of the volume flow measurement is really easy with the App, partly due to the fact that you can carry out parametrization of the outlet (dimension, geometry) intuitively. Particularly useful: when adjusting a ventilation system, volume flows of multiple outlets can be cross-checked and compared. Timed and multi-point mean calculation also gives you a quick indication of the average air velocity, for example at a ventilation grille.
