  6. HI98201 ORP Tester
    $223.30

    Please note - All prices are inclusive of GST and not all items are stock items, if you require an immediate solution please contact us today.

    The HI98201 is an ORP tester ideal for use in swimming pools and spas, as it can provide a valuable indication of water quality. This tester utilizes a platinum electrode and Hanna unique renewable cloth junction, that can be pulled out when clogging occurs, reactivating the reference and restoring the electrode.

    Oxidation reduction is a process by which a molecule or ion loses or gains electrons. This occurs most readily in water treatment and in pool and spa maintenance where an oxidizer, such as chlorine, is added to the water to destroy contaminants. The higher the ORP value, the greater the sanitizing power of your water.
