testo 400 universal IAQ instrument – features
Impressive IAQ measurement technology
- High-precision, location-independent, built-in differential pressure sensor
- Integrated absolute pressure sensor
- Measures all IAQ-related parameters: Flow velocity, temperature, humidity, pressure, illuminance, radiant heat, turbulence, CO2 and CO
- Numerous connection options for probes: 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 – so you’ll be equipped for any measuring task
- Compatible with the testo 420 volume flow hood: Simply connect to the testo 400 via Bluetooth, measure volume flow at larger air inlets and outlets and manage all customer and measuring site data on site using one measuring instrument
- For high-precision measurements and less downtime: Adjustment function at up to six measuring points for zero-error display, probe heads 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 for carrying out long-term measurements with the testo 400 IAQ measuring instrument. While the stand-alone data logger 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 provide optimum support for your measuring task. Use the measurement programs for standard-compliant measurements: HVAC grid measurement as per EN ISO 12599 and ASHRAE 111, PMV/PPD as per EN ISO 7730 and ASHRAE 55, draught and turbulence as per EN ISO 7730 and ASHRAE 55, WBGT measurement as per DIN 33403 and EN ISO 7243, NET measurement as per DIN 33403
- Complete the measurement along with full documentation including photos, comments and your own logo at the customer’s premises, and send by e-mail (via WLAN)
- Customer and measuring point management is carried out on the measuring instrument itself – for efficient work on site.
- Smart-touch display for intuitive operation of the IAQ measuring instrument
- testo DataControl PC software for further analysis, archiving and documentation of measurement data on your computer
- Built-in WLAN and Bluetooth® interfaces: Send measurement reports directly on site or print them out with a suitable printer
