- Extended battery life — up to one month of use on standard 8-hour shifts (configuration dependent); full recharge in under 3 hours
- Compact and lightweight — just over 10 cm tall and 135 g
- Bluetooth and NFC connectivity to Crowcon Connect via IQhub for live data, remote configuration and compliance tracking
- Fast automatic bump tests (<10 seconds) and calibrations (<30 seconds) through IQhub
- Single-button operation for multiple functions
