Gas detector UnoIQ

chlorineammoniamethane

Product overview
The UNOIQ is a personal, rechargeable single-gas detector with modular, field-serviceable sensor trays and optional wireless connectivity. Designed for demanding industrial environments, it supports live data, device configuration and asset management via the Crowcon Connect cloud platform.

Key features

• Personal, rechargeable single-gas detector
• Modular, serviceable sensor trays: plug-and-play pre-calibrated trays that can be swapped without manufacturer intervention
• Extended battery life with fast recharge (0–80% in ~2 hours; 0–100% <3 hours)
• Seamless hub integration (IQhub) for automated bump testing (<10 s), calibration (<30 s), configuration and compliance reporting
• Multiple alarm methods: visual, vibrating and audible (95 dB); supports low/high, TWA and STEL
• Compact, lightweight design with one-button operation
• Upgradeable to dual-gas detection

Modular sensor tray benefits

• Swap pre-calibrated sensor trays in the field without returning the device to the manufacturer
• Reduce downtime and maintenance costs
• Plug-and-play flexibility to target different gases

Extended battery life

• Up to one month between charges depending on sensor and usage (e.g., 31 days for O2 on 8-hour shifts)
• Quick recharge: 0–80% in ~2 hours; 0–100% <3 hours

Seamless hub integration

• Dock-and-go operation with IQhub
• Automated bump tests (<10 s) and calibrations (<30 s)
• Compliance reporting and simple asset management
