Intelligent probes - VAC set

The compact VAC set includes four intelligent probes suitable for the most common measurements made by VAC engineers: Testo 405i Warm Telescope Thermometer, Testo 410i Thermo-Anemometer with Propeller, Testo 605i Thermo-Hygrometer and Testo 805i Infrared Thermometer. In combination with a smartphone or tablet, they can be used to measure surface temperatures, humidity, air flow rates and volumetric flow rates to air conditioning systems. With the mobile app, users can easily read the metrics directly on their phone or tablet. In the mobile application, measurement parameters (such as humidity or temperature) can be deleted, added, or changed by one click. Besides, the mobile application offers specific menus such as the identification of areas with mold risk, automatic air flow calculation at ventilation grids or pipelines by easy parameterisation of pipe or grid sections (size and shape).
All measured values can be displayed both in graphical and tabular form. The measurement reports can thus be saved in PDF or Excel format and sent to any email address. The carry case allows safe and safe transportation and storage of smart wells.
So the probes are always handy when they are needed.

The VAC for Ventilation and Air Conditioning Service consists of: Testo 405i, Testo 410i, Testo 605i, Testo 805i, VAC, batteries, factory calibration certificate.
