Multi-Function Air Quality (IAQ) Meter – Testo 400

testo 400 – multifunctional air quality measuring device

Impressive indoor air quality measurement technology

Integrated high precision differential pressure sensor

Integrated absolute pressure sensor

Measure all IAQ related parameters such as: Flow, temperature, humidity, pressure, light intensity, radiant heat, turbulence, CO2 and CO

Connect up to 8 probes at the same time: 2x cable probes (TUC), 4x Bluetooth probes, 2x TC type K thermocouple probes

Compatible with a wide range of Bluetooth probes and cables – making every measurement task easier

For measurements requiring high precision and less downtime: the testo 400 can replace the probe without restarting the instrument

Long-term monitoring of indoor air quality: with the IAQ data logger (optional) that operates independently of the testo 400. You can therefore take the testo 400 IAQ on to other measuring tasks while the long-term IAQ monitoring is still in progress.

Measurement, management and operation program: Smart, intuitive, practical

Complete measurements and full documentation including photos, comments and customer's own logo

Create and send reports via e-mail (via WLAN) directly on the testo 400

Measurement management is carried out on the testo 400 IAQ instrument itself

Operate and display data intuitively on large touch screen

The testo PC DataControl software for personal computers is used to analyse and store measurement data.

Integrated WLAN and Bluetooth connection protocols for: sending reports via email or printing data on site with the Testo fast printer (optional)
