Entrance 3 and pure air entrance 4, concentration Standard Gases air chamber 1 to be measured respectively with effusion meter 5 and
Bypass flow meter 6 is connected, and effusion meter 5 is connected with standby test examination instrument 7, bypass flow meter 6
It is connected with drain 8.
In the embodiment above, ammonia pure gas entrance 2, nitrogen inlet 3 and pure air entrance
4 are connected with first-class gauge, second gauge and the 3rd effusion meter respectively.
In the embodiment above, first-class gauge, second gauge and the 3rd effusion meter respectively with
Concentration Standard Gases air chamber 1 to be measured is connected.
In the embodiment above, ammonia detector metering and calibrating device also includes display part.
In the embodiment above, display part is arranged with liquid crystal display screen.
In the embodiment above, ammonia detector metering and calibrating device also includes Data Input Interface
And data output interface.
In the embodiment above, ammonia detector metering and calibrating device also includes data processor.
Ammonia detector metering and calibrating device of the present utility model, its circuit connection section divides such as Fig. 1
Shown in carry out type selecting, connection, one has three road air inlets, connects ammonia, nitrogen and clean respectively
Net air, is connected to three effusion meters 5 after three air inlets, three effusion meters 5 are all connected to
One concentration Standard Gases air chamber 1 to be measured, after the mixed air mixing of concentration Standard Gases air chamber 1 to be measured
