OCPF81-LH11E21 – Flat Surface pH Sensor with 3/4” MNPT Housing
  • OCPF81-LH11E21 – Flat Surface pH Sensor with 3/4” MNPT Housing

    SKU: OCPF81-LH11E21-ISI

    OCPF81-LH11E21, Flat surface pH sensor with 3/4” MNPT housing for flow and immersion installations, 15’ cable and BNC.


    Key Features

    • Porous Teflon junction delivers high performance and low maintenance
    • Double chamber reference system prevents fouling in harsh industrial conditions
    • Durable 0-14 pH sensitive glass can withstand CIP treatment and operating temperatures up  to 110°C, 230°F
    • PT100 fast action Temperature Compensation optional
    • Self-cleaning flat surface pH membrane option


    About Internal Plunger

    • This feature was patented by Innovative Sensors in 1982 and is available on most industrial sensors
    • Competitor’s sensors require mounting 15 degrees off horizontal. The expansion air bubble that exists in the pH sensing internal can migrate to the tip of the sensor and cause an internal disconnect
    • Internal plunger allows for expansion of the liquid without the need for an air bubble
    • Enables mounting in any configuration (360 degrees)


    About Porous Teflon Junction

    • This feature was originally patented by Innovative Sensors in 1978
    • The Teflon junction material is uniform in porosity which allows for precise electrolyte flow into measuring sample. This material also resists clogging by dirt and organic deposits that can lead to electrode failure
