Abstract: PURPOSE:To stably measure the concn. of ammonia nitrogen in the water with high sensitivity by providing a standard soln. incorporating mechanism which incorporates the standard soln. of the ammonia nitrogen at an arbitrary ratio into the test water mixed with an alkali agent. CONSTITUTION:The test water is continuously introduced from a water collecting tank 21 into a measuring cell 22. The standard NH4Cl soln. is incorporated into the test water from a standard soln. tank 24 and NaOH from an alkali tank 23 in the mid-way. A stagnating part for the test water, a gaseous phase part of the constant volume in the upper part of the stagnating part and an ammonia electrode 25 in contact with the gaseous phase are provided to the measuring cell 22. The electrode output is first held while the incorporation rate of the standard soln. is held constant. The incorporation rate of the standard soln. is so adjusted that the electrode output changes by a constant rate from the holding value thereof. The concn. of the ammonia nitrogen in the test water is calculated by an arithmetic unit 26 from the change rate of the incorporation rate of this time.
