The City Technology 1854-932-30049 is an ammonia gas sensor cartridge designed for 4 series adaptation. This electrochemical measurement component features a standard measuring range of 0 to 1000 ppm and a sensitivity range of 8 nA/ppm ± 4 nA/ppm. Engineered for reliable gas detection, the 1854-932-30049 provides a zero current of less than ± 40 nA at 20 °C and a resolution under 12 ppm at 20 °C, maintaining a full scale linearity of less than 5%. This sensor operates efficiently in temperatures ranging from -20 °C to +40 °C and handles a non-condensing humidity range of 15% to 90% R.H., with no effect of humidity on the zero reading. It exhibits a long-term sensitivity drift of less than 10% per 6 months. The sensor has a life expectancy of greater than 24 months in air and includes a 12-month warranty.
