Crowcon Companion

Crowcon Companion - your field companion for Crowcon's IQ range of portable gas detectors. The Companion app turns your phone into a control center for the UnoIQ, DuoIQ, and DetectiveIQ. Calibrate, bump test, assign operators, and sync instrument data — all without a laptop, cable, or trip back to the office. Connect your way: Bluetooth — Pair with nearby detectors to view live data, run calibrations, and manage configuration. NFC tap — Hold your phone to the back of a detector for an instant compliance check. No pairing, no menus. Know your fleet at a glance: Every connected device shows a full status dashboard: battery level, firmware version, compliance state, and connection type. Calibration and bump test due dates are displayed with a clear countdown in days or months, so nothing lapses unnoticed. A detailed condition report confirms the device is fault-free and ready for the field. Assign detectors in seconds: Field engineers can assign a detector to an operator directly from the app - over Bluetooth or with a quick NFC tap. No more logging into a portal or waiting for a web workflow. Returns are just as fast, so devices move between people and shifts without friction. Keep logs and clocks in sync Read instrument logs over Bluetooth, sync them with Crowcon Connect and keep device clocks accurate with a one-tap time sync. Both work without a sign-in - handy for quick field maintenance between jobs. See what your detector sees: Per-channel screens give you deep visibility into the air around your team: Live gas concentrations with rolling trend graphs Exposure metrics including STEL and LTEL for toxic gases such as H₂S Configured Alarm 1 and Alarm 2 thresholds, so you always know when the hardware will trigger Full sensor metadata — gas type and range, expiry dates, last calibration, last bump test Built for safety managers and field engineers: Whether you're a safety manager verifying a detector before a shift, or an engineer maintaining a fleet across multiple sites, Crowcon Companion gives you the confidence that every device in the field is healthy, compliant, and keeping your people safe. Calibrate, Bump test and configure your IQ device via self-service engineer mode or a Crowcon Connect sign-in.
