The GasAlertQuattro four-gas detector is tough and dependable, combining a wide range of capabilities with a simple one-button operation. The GasAlertQuattro is always ready thanks to its flexible power options. For easier onsite auditing, the graphic LCD shows easily identifiable icons that represent operational information such as bump tests and calibration status. The IntelliFlash technology gives visual confirmation of the gas detector performance and compliance in real-time. The GasAlertQuattro is fully compatible with BW Technologies by Honeywell’s MicroDock II automatic test and calibration system, making it suitable for a wide range of industrial applications, including confined space entry.
