Rugged and reliable, the GasAlertQuattro four-gas detector combines a comprehensive range of features with simple one-button operation. With flexible power options, the GasAlertQuattro is always ready. The graphic LCD displays easy to identify icons that indicate operational information, such as bump test and calibration status for simplified onsite auditing. IntelliFlash provides continuous visual confirmation of detector operation and compliance. Suited to a wide range of industrial applications including confined space entry, the GasAlertQuattro is fully compatible with BW’s MicroDock II automatic test and calibration system.
GasAlertQuattro QT-XUHM-R-Y-NA-CS
The GasAlertQuattro displays real-time gas concentrations readings for up to four gas hazards including hydrogen sulfide (H2S), carbon monoxide (CO), oxygen (O2) and combustible gases (%LEL & % by volume). Audible, visual & vibrating alarms alert users to unsafe conditions while downloadable datalogging provides exposure reporting.
The GasAlertQuattro features IntelliFlash, a green LED confidence flash that verifies normal operation to both the user and supervisors from up to 20 ft. / 6.10 m.
With easy to identify bump test & calibration icons and power options that outlast normal shifts - 20 hours with rechargeable batteries and 14 hours with alkaline batteries.
- Minimize costs and training with one-button operation
- Field-proven SureCell sensors offer an unprecedented performance in even the harshest environments
- Interchangeable power options with extended battery runtimes for longer shifts
