Description
testo 400 is the universal measuring instrument for all TAB / 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, including measuring points, directly in the instrument - work directly and efficiently on site
- Complete and send measuring values with full documentation, including photos, comments andown 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
Applications:
- Air flow measurements: Flow measurements in ducts, at outlets and on filters as per ASHRAE 111
- High-precision, location-independent and built-in differential pressure sensor, smart and intuitive measurement programs for IAQ measurements in accordance with the standards, creation of documentation on site, e-mailing of reports.
- Measurements in laboratories and clean rooms: Flow measurements in fume cupboards, differential pressure measurements and laminar flow measurements in clean rooms, humidity measurements in clean rooms
