Features:

  • 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 & 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

Reliability

  • 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.
