The nitrogen analyzer can test a data in about one minute, which has the characteristics of quick response, high stability and good repeatability. This instrument is much better than the current zirconia oxygen analyzer, gas chromatographic oxygen analyzer, manual oxygen analysis by copper ammonia method, and oxygen analysis by insurance powder absorption method. The price of the instrument is relatively low and it is easy for users to accept.
This instrument calculates nitrogen concentration by measuring oxygen concentration. The method is that the concentration of nitrogen in the gas is converted into electrical signal by oxygen electricity, and the nitrogen concentration in the measured gas is directly displayed after the conversion by subtracter. This instrument USES 79.0 air calibration method, convenient operation, and set the range automatic conversion circuit, when the nitrogen concentration is higher than 95.0, then the instrument range automatic conversion, reading of 95.00, the instrument measuring range is 99.99, the instrument also has lower limit of adjustable setting circuit, set the range of 91.0 ~ 91.0, the alarm indicator, the unit output - 220 v5a contact signal, with 4-20 ma output signal, oxygen levels (0 ~ 1%) can be connected to the recorder.
