  1. HI98121 ORP/pH/Temperature Tester
    $179.00

    Ships within 1-2 Business Days

    The HI98121 is a waterproof pH, ORP and temperature meter. The housing of this tester has been completely sealed against humidity and is designed to float. Electrode replacement with the stainless steel round connector means there are no pins to bend or break during replacement. When the cloth junction becomes clogged and response time is sluggish, simply pull out 3 mm (1/8”) to clear the clogging which will improve response time and stability. The exposed stainless steel temperature sensor on these models facilitates faster and more accurate temperature measurement.

  3. HI98201 ORP Tester
    $105.00

    Ships within 1-2 Business Days

    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.
