Testo 400

The Testo 400 (0560 0400) Universal Air Flow and IAQ Measuring Instrument with Touchscreen Display is the universal measuring instrument for all TAB / Commissioning and IAQ professionals. Users can measure, analyze and document air flow, air pressure, IAQ and comfort level parameters using just one instrument - simply, conveniently and in compliance with the standards. High-quality measuring technology, intuitive measurement assistants, and versatile documentation options make the testo 400 the perfect partner for your day-to-day work.

As an expert in the field of air conditioning and ventilation, you will find the testo 400 universal Air flow and IAQ measuring instrument ideal. The measuring instrument with a built-in measurement assistant provides optimum support for carrying out air flow and comfort level measurements in accordance with the standards like NEBB and ASHRAE, as well as for Testing, Adjusting & Balancing (TAB) air conditioning and ventilation systems.

Impressive IAQ Measurement Technology

• High-precision, location-independent and integrated differential pressure sensor meeting the NEBB Instrument requirements for Air pressure
• Integrated absolute pressure sensor
• Measures all IAQ-related parameters (probes sold separately): Flow, temperature, humidity, pressure, illuminance, radiant heat, turbulence, CO2 and CO
• Numerous connection options for probes (sold separately): 2 x cable probes (TUC), 4 x Bluetooth probes, 2 x type K thermocouple probes
• Compatible with a wide range of available Bluetooth and cable probes (sold separately) - ensure you will be equipped for any measuring task
• For high-precision measurements and less downtime: Adjustment function at up to six measuring points for zero-error display, probe heads (sold separately) can be replaced without restarting the IAQ measuring instrument, high-quality probes with an intelligent calibration concept (probe calibration independent of the measuring instrument)
• Long-term monitoring of the indoor air quality: Order the IAQ data logger (sold separately) for carrying out long-term measurements with the testo 400 IAQ measuring instrument. While the stand-alone data logger (sold separately) is carrying out the IAQ measurement, you can use the IAQ measuring instrument for measurements elsewhere

Smart, Intuitive, Practical: Measurement Programs, Measurement Data Management and Operation

• For error-free measurements in accordance with the standards: Smart, intuitive measurement menus and evaluation of readings according to the traffic light principle provide optimum support for your measuring task. Use the measurement programs for standard-compliant measurements: HVAC volume flow grid measurement as per ASHRAE 111, PMV/PPD as per ASHRAE 55, draft and turbulence as per ASHRAE 55
• Complete the measurement and full documentation including photos, comments and your own logo on site at the customer's premises, and send by e-mail (via WiFi)
• Customer and measuring point management is carried out in the measuring instrument itself - for efficient work on site
• Smart-touch display for intuitive operation of the IAQ measuring instrument
• esto DataControl PC software for further analysis, archiving and documentation of measurement data on your computer
• Built-in WiFi and Bluetooth interfaces: Send measurement reports directly on site or print them out with a suitable printer (sold separately)
