XgardIQ is an intelligent and versatile gas detector and transmitter compatible with Crowcon's full range of sensor technologies. Available fitted with a variety of flammable, toxic or oxygen gas sensors

Providing analogue 4-20mA and RS-485 Modbus signals as standard, XgardIQ is optionally available with Alarm and Fault relays and HART communications. The 316 stainless steel are available with three M20 or1/2"NPT cable entries

Easy and safe to use

  • OLED display - Bright, clear display indicates gas level and detector status even in dark locations
  • Non-intrusive calibration - Zero and calibration functions are performed via the display and keypad, without the need for a hot-work permit or any special tools (e.g. no magnetic wand required)
  • +ve Safety indicator - Confirms the detector is operating safely at a glance
  • Event log function - Stores all alarm, fault and maintenance events to provide a history of detector use

Simple installation and maintenance

  • Universal transmitter - Common transmitter for Crowcon's full range of sensor technologies
  • Hot-swap sensor modules - Sensors can easily be replaced using one hand without requiring tools or a hot-work permit
  • Auto-sense function - Automatically detects whether the control system is 4-20mA current sink or source and sets itself appropriately, eliminating the risk of being incorrectly set
  • Auto-configure function - Detects when a sensor module is plugged-in and uploads the appropriate gas type, range, units and alarm levels


  • Smart Bump and Speedy Bump test functions - Enable sensor health and response to be verified quickly and easily using test gas. Process is automated and provides a reminder when a bump test is due
  • Calibration due warning - Reminds the user when calibration is due to ensure that sensors remain operational and accurate at all times
  • Sensor range selection - User can set the full-scale range of the sensor via the display menu according to site or specific location requirements
