Description
The testo 400 IAQ kit is the universal measuring instrument for all Commissioning and IAQ professionals, enabling them to measure, document, and analyze all IAQ parameters with just one instrument.
As consultants, experts, technical service providers, or service technicians in the air conditioning and ventilation sector, the testo 400 therefore support sin the truly smart performance of measuring tasks. Relevant quality parameters in industrial production and manufacturing processes can also be reliably and accurately checked using the testo 400.
Features:
- 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, measuring points, directly in the instrument - work directly and efficiently on site
- Complete and send measuring values with full documentation, including photos, comments and 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
