Description: Condition:NEW Package included: 1 pc British Alfa Alphasense B4 series sensor SO2-B4 NO2-B4 NO-B4 CO-B4 OX-B431 H2S-B4 environment detection 1. Main parameters of carbon monoxide sensor CO-B4 Overload: 2000ppm Response time: < 15s Size: 32.3 x 16.5 Carbon monoxide detection range: 0-1000ppm Sensitivity: 420 to 650 nA/ppm Zero: -100 ~ 10nA Two. Typical application of carbon monoxide sensor CO-B4 Air quality trace carbon monoxide monitoring, carbon monoxide gas transmitter Ozone / nitrogen dioxide sensor OX-B431 (original OX-B421) is introduced in detail. Introduction of ozone / nitrogen dioxide sensor OX-B431 OX-B431 sensor is a new substitute product based on the original OX-B421 sensor. It has better stability and can detect O3 and NO2. If both gases exist in the environment, to accurately quantify O3, it is recommended to add NO2-B43F to compensate for the correction; if only one of the two gases exists, the gas concentration can be directly quantified. Two, ozone / nitrogen dioxide sensor OX-B431 ozone detection technology parameters Response time: < 45s Size: 32.3 x 16.5 Ozone detection range: 20ppm Overload: 50ppm Sensitivity: -225 to -550 nA/ppm Three. Ozone / nitrogen dioxide sensor OX-B431 technical parameters for NO2 detection Response time: < 35S Size: 32.3 x 16.5 Nitrogen dioxide detection range: 20ppm Overload: 50ppm Sensitivity: -250 to -650 nA/ppm Sulfur dioxide sensor SO2-B4 is introduced in detail. 1. Main parameters of sulfur dioxide sensor SO2-B4 Range: 100ppm Overload: 200ppm Response time: < 30s Size: 32.3 x 16.5 Linear range: 0-10ppm Sensitivity: 275 to 475 nA/ppm Contact Us: (1).
