This instrument is used measuring the air velocity/ air flow rate from the air terminal.Make TSI
A particle counter is an instrument that detects and counts particles. By its very nature a particle counter is a single particle counter, meaning it detects and counts particles one at a time. Make TSI
This instrument is used to check the filter intergrity in HVAC and clean room application. This test will confirm whether the filter installed in the system is leakroof and is performing as per design.
This is used for PAO test where in the filter integrity will be tested.
This is used for testing the flow pattern inside the clean room. The clean room should have a peculiar airflow pattern to be maintained for better scavenging effect.
This is also used for measuring the air velocity and thus the air flow rate from the air terminals. This will define the performance of the air distribution system.
A data logger is an electronic device that records data over time or in relation to location either with a built in instrument or sensor or via external instruments and sensors. Increasingly, but not entirely, they are based on a digital processor (or computer).
Hot wire anemometers use a very fine wire (on the order of several micrometres) electrically heated to some temperature above the ambient. Air flowing past the wire cools the wire. As the electrical resistance of most metals is dependent upon the temperature of the metal (tungsten is a popular choice for hot-wires), a relationship can be obtained between the resistance of the wire and the flow speed.
