<p>Equipment continuously measures the ammonia in a gas, having a sampling pipe delivering the gas. Second pipe delivers an acid, which absorbs the gas in a vessel so as to form an ammonia mixt., from which gas is then sepd.. Third pipe supplies base material for mixing with the mixt., whose ammonia content is then measured, pref. by a gas-sensitive electrode in a measuring vessel.</p> |
