Description

The key benefit of the ThermoAir 20 Omni-directional probes are significantly easier and faster to deploy for area-based measurements, as the operator does not need to waste time aligning the probe to the perceived direction of the flow. For tasks like checking the average air speed across a ventilation grille or mapping the velocity profile of a large room, the omni-directional probe simply needs to be placed at the measurement point.

This feature is particularly valuable for comfort testing and validating ventilation standards in occupied areas, like within a cubicle farm or near hospital beds. These instruments are often used for taking numerous measurements across a fixed grid to calculate an area-averaged air velocity, which is a key parameter for Indoor Air Quality (IAQ) and thermal comfort assessments. The portable handheld ThermoAir 20 display simplifies the measurement process saving time and reducing the margin of error associated with improper directional alignment across dozens of measurement points.
