Standard-compliant volume flow measurement
With the universal IAQ instrument, you can measure volume flows in ducts and at outlets efficiently, intuitively, and in compliance with standards.
Interactively guided measurement menus
The testo 400 helps you to work in compliance with DIN EN 12599 or ASHRAE 111. It guides you step by step through the measurement, reliably preventing any incorrect measurements from being made.Convenient measurement
Telescopes with easy-to-read scaling make it really convenient to work in ducts.Efficient data management
Customer and measuring point information can be transferred from software allowing complex series of measurements to be conveniently analysed on a PC down to the very last detail.Intelligent calibration concept
The adjustment function allows you to store the calibration deviations determined during calibration at up to six measuring points in the digital probe. This gives you a zero-error display.
