RIKA RK500-15 High Reliability Liquid Ammonium ion NH4+ Meter Sensor Transmitter for Water
The RK500-15 Ammonia Nitrogen Sensor uses an ammonium ion electrode based on PVC film to test the content of ammonium ion in water. With temperature compensation, the measurement is fast, simple and accurate. The internal reference liquid of the ammonium ion electrode exudates from the microporous salt bridge very slowly. The forward exudation of the reference liquid can last for more than 20 months, and the service life of the electrode is longer than that of the ordinary industrial electrode.
