-
Measures all IAQ-related parameters: Flow, temperature, humidity, pressure, illuminance, radiant heat, turbulence, CO? and CO
-
High-precision, location-independent and integrated differential pressure sensor
-
High-quality digital probes and an intelligent calibration concept
-
Document measuring values directly on the customer's site and send them by e-mail, or further analyze them using the testo DataControl PC software
-
Smart and intuitive measurement programs:-
-
HVAC grid measurement in accordance with EN ISO 12599 and ASHRAE 111
- PMV/PPD in accordance with EN ISO 7730 and ASHRAE 55
- Draught and degree of turbulence in accordance with EN ISO 7730 and ASHRAE 55
- WBGT measurement in line with DIN 33403 and EN ISO 7243, NET measurement in accordance with DIN 33403
testo 400 is the universal measuring instrument for all IAQ professionals, enabling them to measure, document and analyze all IAQ parameters with just one instrument. Your benefits:
- 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 meas- uring points, directly in the instrument - work directly and efficiently on site
- Complete and send measuring values with full documen- tation, including photos, comments and your own logo directly on site – get to the next job faster
- Probe heads can be changed without restarting the instru- ment – easy handling with no lost time
- Calibration of probes which is independent of the measur- ing instrument and adjustment function at up to six meas- uring points for zero-error display – fewer downtimes and high-precision measurements
As consultants, experts, technical service providers or ser- vice technicians in the air conditioning and ventilation sec- tor, the testo 400 therefore supports you in the truly smart performance of your measuring tasks. Relevant quality parameters in industrial production and manufacturing pro- cesses can also be reliably and accurately checked using the testo 400.
