    Description


    SEM 5000

    Portable Methane Detector

    Geotech SEM 5000 is a portable methane detector used to improve reading accuracy and to reduce potentially harmful greenhouse gases.


    Thanks to patented laser technology, the Geotech SEM 5000 is selective, specifically to methane and is able to detect emissions from 1-10000ppm or from 0.1% to 100% v/v concentration.
