Shandong Xinze, as a professional manufacturer of flue gas analyzers, compares the principles of several flue gas analyzers that are more common in the market, and hopes to help everyone. | low cost |Easy operation | ready to use | There may be cross interference between gases in the sample gas | easy to poison | Sensor life is limited | poor reliability | poor overall maintenance | Moderate cost |Common technical operation is convenient | moderate sensitivity |The sample gas is required to be dried, and the use of a suitable cooler or dryer will result in NO 2 Loss 10-20% (NO 2 is very soluble in water) |Low dynamic range - generally the lowest range is 100ppm. |Independent conversion of NO 2 to NO – adds cost. |Additional cooler or dryer |NO 2 sensitivity is poor |Interference with H 2 O and the presence of other gases present in the sample gas |NO 2 can be directly measured by ultraviolet light | No coolers and dryers required | Easy to operate |Long Life NO 2 Lamp - (German Plasma) |Only NO or NO 2 is reasonably cost effective | Moderate sensitivity - generally a minimum range of 100ppm. | NO and SO 2 present crosstalk - If the SO 2 in the sample gas there occur problems |NOX measurement is costly – use two separate NO and NO 2 analyzers, or A separate NO 2 -NO reformer (thermal UV analyzer is better than infrared analysis A lot of expensive) |NO uses a xenon lamp for short life Medical Equipment,Treatment For Facial Rejuvenation,Blood Plasma Centrifuge Machine,Dull Roughness Improvement Changzhou Timerein Biotechnology Co. , Ltd. , https://www.timereinbiotech.com principle Advantage Disadvantage Principle of electrochemistry Infrared principle Principle of ultraviolet light
