Testo 400 multifunctional measuring instrument is designed for professionals working with air conditioning and ventilation systems. The device can also be used by professionals checking indoor air quality. The instrument can measure air flow, temperature, humidity, pressure, illumination, radiant heat, turbulence, CO and CO2 parameters (depending on the probe connected). The unit has two cameras (front and rear) that allow you to take pictures and to supplement the measurement documents with a view of the object.
Testo 400 Universal IAQ instrument has:
- High-precision meter with integrated differential pressure sensor
- Integrated absolute pressure sensor
- Several different ways to connect sensors and probes: 2 x wired connections, 4 x Bluetooth probes, 2 x K probes
- Extremely wide selection of different sensors and probes
