*Important Calibration Information:

This instrument comes supplied with a ‘manufacturers calibration protocol’ please note this is NOT a traceable calibration certificate. A calibration protocol is a statement of values or tolerances within the desired range that the instrument was reading at the point of manufacture. A calibration protocol may not be an acceptable statement of accuracy according to industry accreditation bodies.
If you require a traceable calibration certificate accredited to your business, please select this option where applicable from the drop-down field below.

Comes supplied with:

testo 425 - Thermal hot wire anemometer with App connection and fixed telescope (max. 820 mm)
Transport bag
Calibration protocol
3 x AA batteries

Details:

Optimally adjusted air conditioning and ventilation systems are a decisive factor for modern buildings. Accordingly, it is important to use the appropriate measurement technology to ensure that the flow, temperature and volume flow in the ventilation duct are correct. The testo 425 thermal anemometer is your fast, easy and precise companion. The cable-connected telescopic probe can be extended up to 820 mm, making it easier to work overhead or in large diameter ducts. All relevant calculations, such as volume flow or time and point averages, are performed automatically by the particularly robust and compact measuring instrument. Incidentally: Configuration of the measuring instrument, display and storage of measured values as well as documentation are all particularly convenient with the testo Smart App. This also turns your smartphone into a second display.

Key Features:

Simple, fast and precise flow and temperature measurement plus volume flow calculation in the ventilation duct
More flexibility for duct measurements with the cable-connected telescopic probe (maximum length 820 mm)
Fast in-app (duct) configuration, graph history, second screen and measurement data memory in the testo Smart App
Timed and multi-point mean calculation

The compact hot wire anemometer testo 425 with telescopic probe is ideal for simple, fast and precise determination of flow velocity and volume flow in ventilation ducts of air conditioning and ventilation systems. The connection to the testo Smart App enables configuration, display (also as second screen) and storage as well as documentation of the measurement directly in the App.

The testo Smart App

Simple and fast: Measurement menus for
numerous applications provide optimum support in
configuring and carrying out the measurement
Clear graphical presentation of readings, e.g. as a
table, for quick interpretation of results
Create digital measurement reports including photos as PDF/CSV files on site and send via e-mail
