testo 400 Air Flow Kit - For TAB / Commissioning Professionals

testo 400 is the universal measuring instrument for all TAB / Commissioning and IAQ professionals, enabling them to measure, document and analyze all Airflow and IAQ parameters with just one instrument.

Smart support through stored measurement menus and evaluation of measuring values according to the traffic light principle – for error-free measurements
Manage all the relevant customer data, including measuring points, directly in the instrument - work directly and efficiently on site
Complete and send measuring values with full documentation, including photos, comments and your own logo directly on site – get to the next job faster
Probe heads can be changed without restarting the instrument – easy handling with no lost time
Calibration of probes which is independent of the measuring instrument and adjustment function at up to six measuring points for zero-error display – fewer downtimes and high-precision measurements

As consultants, experts, technical service providers, or service technicians in the air conditioning and ventilation sector, the testo 400 therefore supports you in the truly smart performance of your measuring tasks. Relevant quality parameters in industrial production and manufacturing processes can also be reliably and accurately checked using the testo 400.
