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
Remote Sensor – Improves probability of detection
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
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.
