     Tracer Gas Monitoring System for Ventilation

     DKG-VEN

    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.

    Features

    Photoacoustic Spectroscopy with patented cantilever pressure sensor

    Low detection limithigh accuracy

    Fast response time

    To measure tracer gas such SF6, Freon 134a, N2O,ethane, CO2 and VOC’s

    Multipoint sampler, extended 12 to 64 sampling point

    No pre-treatment, No consumables, No carrier gas 

    Applications

    Ventilation evaluation in buildings like air exchange, air of age

    Ventilation efficiency for HVAC
