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).
