    Online UV Dissolved Ozone Analyzer 

    DK-27TR

    Overview


    The DK-27TR Trace Ozone Analyzer is a special ozone measuringinstrument that uses patented light absorption technology to achieve high precision, high stability, ppb concentration measurement, high reliability and minimum maintenance for the initial Design concept,analytical instrument electrodeless consumables and membrane consumables, no moving parts loss, the only maintenance requirement is to replace the UV lamp every few years, the key industrial advantages include ultra-sensitivity, no drift stability and no other gas cross interference.


    The DK-27TR trace ozone analyzer controller is based on a micro-processing core including analog and digital interfaces, and three available alarm relays.
