35-Series Ammonia Ion-Selective Electrode

  • 35-Series Ammonia Ion-Selective Electrode

The 35-Series Ammonia (NH3) Ion-Selective Electrode (ISE) is a general purpose, laboratory or field electrode offering convenient replaceable membrane modules and excellent performance

Specifications:

Sensor Type: Gas-Sensing - glass pH with gas-permeable membrane

Range: 0.01-17,000 ppm (as NH3)

Sample pH Range: >11 (required by addition of ISA)

Slope: 56 ± 3 mV/ decade

Interferences: volatile amines (gaseous)

    Features:

    Gas-sensing technology in a standard 12mm diameter and 120mm length

    • The gas-permeable membranes can be replaced if they foul or tear
    • This electrode correlates a pH change to the concentration of ammonia after the ammonia in the sample is made gaseous, by the addition of ISA (pH>11)
    • Suitable for all general purpose or more advanced applications
