testo 400 – the multi-tasker for IAQ professionals Measures all IAQ-related parameters: Flow, temperature, humidity, pressure, illuminance, radiant heat, turbulence, CO2 and CO High-precision, location-independent and integrated differential pressure sensor High-quality digital probes and an intelligent...
1. The carrier gas needs to pass at a sufficiently low velocity. The solid particulates, which have higher density than the surrounding gas, settle on the base of the chamber through gravity influence, and then be collected and removed by dust hoppers in the bottom. Uniform flow within the ...
The principle is to generate such high air velocity that a shield against pressure difference, temperature difference, and wind velocity is sustained. However, it is not possible to have complete separation by an air curtain. The main reason is that the jet entrains air (from both sides) ...
An air rate meter according to the vortex velocity principle has a measuring tube, in which at least one disturbance member is located for the purpose of vortex formation and in which at least one pressure transducer for generating vortex pulses is provided; the pressure transducer is followed ...
We have a brand new WBGT index meter that is now on sale. It is specially used outdoors. In order to protect construction sites and people working outdoors in high temperatures, the instrument prov... View More 2025-03-18 Application of Airflow Velocity Senso... ...
In the optical automatic detection instrument for defects of glass substrate, the principle of the air flotation is shown in Fig. 1: The air-flotation plate is provided with positive pressured air injection holes and negative pressured vacuum holes, which are arranged in array. The air ejected ...
Microbial Air Sampler is a highly efficient, multi-hole, aspirated sampler based on the Anderson impact principle. The impact velocity is 10.8 m/s, equivalent to the fifth level of the Anderson sampler, which can collect all the particles in the air with diameter greater than 1μm.T...

The ASI is a pressure-operated instrument. It senses the difference between the total pressure measured at a pitot-static tube and the static pressure measured at a ‘static measuring point’, where there is no dynamic component due to air velocity. This principle, and the instrument display, ...
Table 1. Summary of previous work on cabin distributions (velocity field (V), contaminant concentration (C), temperature (T); hotwire (HW), sonic/ultrasonic anemometry (SA/UA), particle tracking velocimetry (PTV), volumetric particle tracking velocimetry (VPSV), particle image velocimetry (PIV)...
