Testo 480, raki- og loftflæðismælir

Testo 480

Manufacturer: Testo
Model: 480

The Testo 480 features a built-in, high-precision differential pressure sensor, suitable for applications such as Pitot tube measurements, filter checks, and cleanroom monitoring. Its wide range of compatible probes allows measurement of the following parameters:

Air velocity and air volume (e.g., for fume hood testing)

Temperature

Relative humidity

Differential and absolute pressure

CO₂ concentration

Illuminance

PMV/PPD (comfort index)

Radiant heat

Turbulence intensity

WBGT index (heat stress)

The instrument can be customized with various optional probes and accessories (e.g., a wireless printer for on-site reporting).
