TOXALERT’S Model TOXEC Series/Sensor/Transmitter modules are compact, micro processor based, cost effective gas sensors designed for fixed installation, continuous monitoring of commercial and industrial facilities. The TOXEC Series is a carbon monoxide (CO) sensor, nitrogen dioxide (NO2) sensor or a combination of both CO and NO2 sensors in one monitor. Each monitor is microprocessor based to insure trouble free, long term
stability and is housed in an architecturally appealing ABS housing with indicators for power and microprocessor running/malfunction. They are designed for easy direct connection to TOXALERT TOX4 and
ToxControl controllers or any DDC, BAS, DCS, PLC’s and other control devices.
