RKI T2A Fixed Gas Transmitter Gas Type:Nitrogen Dioxide (NO2) 0-20 ppm reaching depths up to roughlyThe RKI T2A is a loop powered, two wire fixed gas transmitter built around electrochemical sensing, covering an unusually broad library of toxic gases from common ones like CO, H2S, and NH3 to more specialized targets like HCl, HCN, ozone, phosphine, ethylene oxide, and arsine. A 3 character 7 segment display and magnetic switches let technicians check readings and configuration without opening the enclosure. The T2A draws just 35mA max at 12 35VDC
