The universal air velocity & IAQ measuring instrument testo 400

For us as a technical service provider for air conditioning and ventilation systems, testo 400 is our preferred instrument with its versatility and convenient data management functionalities. It's very easy to use and most importantly, provides reliable readings.

We use testo 400 to determine reliable precise results of the indoor climate. Here the measuring programs for PMV/PPD and draught rate are already stored in the instrument. The flexible attachment of various probes is another plus point of the testo 400 for me. If my applications expand in the future, I can simply purchase additional probes. If a probe breaks or needs calibration, I can send it to the service department separately and continue to use the measuring instrument in the meantime.

The testo 400 IAQ measuring instrument makes you a measurement data billionaire. With its vast memory, we don't have any more headaches about data management and documentation.

The wireless probes are designed with touch display and magnetic mounts for easy attaching to ducts. In addition, the high accuracy of the instrument and accessories are crucial for the pharmaceutical customers we support as a service provider for technical facility management.
