Introduction

The time spent indoor is increasing with the modernization and urbanization process, making the indoor air quality （IAQ）more important than ever.

IAQ relies on many factors, such as temperature, humidity, the concentration of CO2 and VOC’s. One of the effective measures to adjust and improve IAQ is ventilation system.

One of the methods to evaluate ventilation, including natural ventilation and mechanical ventilation, is to monitor the concentration change of tracer gas to calculate the ventilation efficiency. The mostly used tracer gas is selected from SF6, freon 134a, N2O, ethane or CO2.

Our solution

We offer an accurate, reliable and effective solution to evaluate ventilation efficiency by using tracer gas method with highly sensitive Photoacoustic gas monitoring system.

Photoacoustic gas analyzer can measure up to 9 gases and water vapor at the same time. The type of measured gas is selected by the user from a 300+ gas’ pool. Besides tracer gas, other IAQ indicators like CO2 and VOC’s can also be measured, to provide data for the IAQ assessment.
