Photometer Dedicated to Cooling / Closed Systems Water

    • One instrument to carry out all the tests associated with cooling water / closed water systems.
    • Ideal for routine, on-site system monitoring.
    • Photometric measurement for accurate, repeatable results.
    • Easy-to-use, push button technology with step to step guides.
    • Select range of required reagents to complete your kit.
    • Combine with pH, conductivity and drop test chemistries to provide a complete analysis program.


The engineer can select and incorporate the Lovibond® / DTK Water reagents required for the monitoring of specific water treatment inhibitors. Additional components such as pH and conductivity meters and drop test chemistries may also be added to the kit, providing a bespoke and complete analysis program.
