Testo 400 Universal Indoor Air Quality instrument (IAQ)
The testo 400 is the universal measuring instrument for all Indoor Air Quality professionals.
Measure, analyse and document all IAQ and comfort level parameters using just one instrument. The comprehensive selection of IAQ probes designed for a multitude of IAQ applications makes testo 400 the perfect partner for your day-to-day work.
The 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 high-precision measurements and less downtime:
- Smart, intuitive measurement menus and evaluation of readings provide optimum support for your measuring task
- 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)
- Error-free measurements in accordance with the standards:
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.
Long-term monitoring of the indoor air quality
Purchase the optional IAQ Data Logger for carrying out long-term measurements. While the stand-alone data logger is carrying out the IAQ measurement, you can use the IAQ measuring instrument for measurements elsewhere.
