Description
Ideal for Testing, Adjusting and Balancing (TAB) / (Retro)-Commissioning Professionals (BSC / RCx) or Cleanroom Performance Tester (CPT) the testo 400 Air Flow kit meets highest standards when it comes down to accuracy and durability for air velocity measurements on HVAC systems.
Features:
- A measuring instrument for all climate-related parameters
- Measurement assistant for volume flow measurement according to ASHRAE 111 and NEBB air velocity and air pressure instrument requirements.
- You have all measurement locations withat all times and ready atfingertips.
- Wireless Bluetooth probes for maximum
- freedom of movement at work.
- Create and finalize measurement reports on site directly on the testo 400.
- 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: Duct traverse (Hot wire probe / Pitot tube) Flow measurements at outlets (Rotating Vane Anemometer) as per ASHRAE 111 and NEBB Instrumentation Requirements in disciplines like TAB/BET/BSC/CPT/RCX
- 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, versatile combination options with IAQ probes
- 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 with additional probes Comfort level measurements: Measurement of indoor air quality or turbulence as per ASHRAE 55, PMV/PPD as per ASHRAE 55.
