Crowcon XgardIQ Fixed Gas Detector Transmitter
Designed to minimise the time users spend in hazardous areas, the Crowcon XgardIQ Fixed Gas Detector is an innovative safety solution.
This intelligent fixed-point gas detector is compatible with the full range of Crowcon sensor technologies. It uses simple hot-swappable sensor modules that are bump-tested and calibrated in seconds, reducing the amount of time the user spends in a hazardous environment.
This branded device provides a bright OLED display that displays status information, while bright LEDs indicate status at a glance. If any abnormal conditions are detected, the LEDs will flash and a warning message will be displayed.
