1ZBK/NH500/TCAmmonia nitrogen electrode consumablesPrinciple of use

（1）ZBK/NH500/TCAmmonia nitrogen electrode consumablesIt is a complete set of ammonia nitrogen electrode consumables made by "ammonia gas passing through a layer of semi permeable membrane (made of Teflon)". The quality of the semi permeable membrane is the core of the entire ammonia nitrogen analysis, directly affecting the results and accuracy of ammonia nitrogen measurement. Imagine if the ammonia nitrogen semi permeable membrane does not permeate ammonia, or if the permeation rate is too low, or if the permeation time is too fast or too slow, it will directly affectmeasureresult. The WTW ammonia nitrogen electrode consumables ZBK/NH500/TC include three ammonia nitrogen membrane heads and one ammonia nitrogen electrolyte bottle.

（2）The property of the semi permeable membrane (made of Teflon) for ammonia nitrogen is selective permeability, which means that only ammonia gas can pass through the membrane, and other gases cannot pass through. WTW ammonia nitrogen semi permeable membrane is a specialized membrane,ammoniaThe transmittance and transmittance time of WTW are both conclusions obtained through rigorous testing. Currently, there are counterfeit ammonia nitrogen membrane heads on the market that cannot replace WTW's original ammonia nitrogen semi permeable membrane in terms of material, transmittance, and transmittance time. It is recommended that users purchase genuine WTW ammonia nitrogen electrode consumables to learn more information.

（3）ZBK/NH500/TCApplied to online ammonia nitrogen analyzer Trescon+OA110, onlineAmmonia nitrogenThe analyzer is specifically designed for water quality monitoring systems andsewage-treatment plantDesigned for controlling and monitoring wastewater, Yang has a compact structure and excellent cost-effectiveness, capable of handling multiple parameter testing environments. Test range: NH4-N: 0.03... 1000mg/l NH4+: 0.00... 1280mg/l

IIZBK/NH500/TCAmmonia nitrogen electrode consumablesReplacement cycle

Depending on the water quality, there may be slight differences, such as between relatively clean surface water andsewageThe replacement cycle of the factory is different.

Suggested replacement cycle: once a week; The replaced membrane head can be regenerated once and can continue to be used after regeneration. Regeneration steps: Soak the replaced ammonia nitrogen membrane head incitric acid（Cleaning liquid）48 hours, then soak in pure water for another 48 hours, and let it air dry naturally in a cool place.

The amount of electrolyte added: When adding electrolyte to the membrane head, the electrolyte should be added to 2/3 of the membrane head, slightly tiltedelectrodeThen tighten the electrode.
