About Air Flow, IAQ & Sound Meters
Air flow, indoor air quality and sound instruments are used for HVAC commissioning, occupational hygiene, environmental monitoring and acoustic testing. Seven Star LLC, an independent supplier in Muscat, supplies these instruments from TSI, Brüel & Kjær, Extech, Fluke and Testo to customers in Oman and the GCC.
Types of air quality meter in this category
Air velocity and ventilation meters such as the TSI VelociCalc 9545, 9565 and 5725, Fluke 925, testo 405i and Extech AN310, and the TSI DP-Calc 5825 micromanometer measure duct flow and pressure. Indoor air quality monitors like the TSI IAQ-Calc 7525 and Q-Trak 7575, DustTrak II 8530 and DRX 8533 aerosol monitors and the P-Trak 8525 ultrafine particle counter assess CO2, comfort and particulates. Brüel & Kjær sound level meters, microphones and ear simulators, and Extech light meters and tachometers complete the range.
How to select a air quality meter
Define the parameters (air velocity, flow, pressure, CO2, temperature, humidity, particulates, noise) and the standards or regulations you report against. Choose probe type for ducts or open areas, data logging and software, and calibration certificates.

Frequently Asked Questions
Thermal or vane anemometer?
Thermal anemometers measure low velocities accurately in ducts. Vane anemometers suit grilles, diffusers and higher velocities.
What does an IAQ meter measure?
Typically CO2, temperature, humidity and sometimes CO, VOCs or particulates, to assess ventilation and comfort.
What is the difference between an aerosol monitor and a particle counter?
An aerosol monitor measures mass concentration such as PM2.5. A particle counter counts particles by size.
Do sound level meters need calibration?
Yes. A field check with an acoustic calibrator before use and periodic laboratory calibration are recommended.
What should I send for a quotation?
The model, or parameters, ranges, probes, logging requirements and quantity.
