Testo 605i - Thermohygrometer With Smartphone Operation

Special Price 14042

Regular Price: 15446.00


The compact testo 605i temperature and humidity measuring instrument features professional measuring technology in an intelligent format: it can be used in conjunction with a smartphone/tablet and the testo Smart Probes App to reliably measure air temperature and humidity in rooms and ducts.


Product Description

In addition to measuring air temperature and relative humidity in rooms and ducts, the thermohygrometer is also suitable for checking air conditioning system humidifiers. When you use the testo 605i in conjunction with the testo 805i infrared thermometer, you can clearly identify areas susceptible to mould via the traffic light principle, with the assistance of a measurement menu that is already stored in the App.


Measure more efficiently using the App


The testo 605i wirelessly transmits the measurement data via Bluetooth to your own smartphone or tablet. With the testo Smart Probes App installed on your terminal device, you can view your readings conveniently. The App also enables the dew point and wet-bulb temperature to be determined automatically. All measurement data is displayed either as a chart or in table form. The measurement data log can then be emailed directly as a PDF or Excel file.
