The TX-6-ND is a low voltage, dual relay Nitrogen Dioxide (ND) detector, and an automatic ventilation controller. The TX-6-ND uses a
microcomputer-controlled, electronic system to measure the concentration of Nitrogen Dioxide, actuate relays and provide a 4-20mA
output. The TX-6-ND has a field replaceable, electrochemical sensor (expected life of 2+ years) and optional gas test and calibration
kits. The TX-6-ND is a low-level meter capable of displaying from 0-20ppm of Nitrogen Dioxide.
