As an expert in the field of air conditioning and ventilation, you will find the testo 400 universal IAQ measuring instrument ideal. The IAQ 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, as well as for adjusting and inspecting air conditioning and ventilation systems.
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 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.
Features:
- High-precision, location-independent, built-in differential pressure sensor
- Integrated absolute pressure sensor
- Measures all IAQ-related parameters: Flow, 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
- 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)
- 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
WLAN)
- 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
- 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
