Product Description

Modern buildings must have air conditioning and ventilation systems that are properly calibrated. In order to verify that the flow, temperature, and volume flow in the ventilation duct are accurate, it is crucial to utilise the right measurement technology. The testo 425 thermal anemometer is your quick, simple, and accurate ally. Working overhead or in ducts with a big diameter is made easier thanks to the cable-connected telescopic probe’s ability to be extended up to 820 mm. The extremely durable and small measurement equipment automatically performs all pertinent calculations, such as volume flow or time and point averages. In addition, the testo Smart App makes it incredibly easy to configure the measuring device, display and store measured information, and create documentation.Your smartphone now serves as a second display as a result.
