BW Technologies GasAlertQuattro 3-Gas Detector %LEL, H2S, CO - Rechargeable Version - Yellow Housing


QT-0WHM-R-Y-NA GasAlertQuattro 3-Gas Detector %LEL, H2S, CO - Rechargeable Version - Yellow Housing by BW Technologies

The GasAlert Quattro is a fully functioning 4 gas detection unit that is both durable and reliable. With a rugged yellow outer casing and built-in concussion proof boot, the gas detector is built to withstand harsh environments and accidental drops. Engineered with the most advanced technology available, the GasAlert Quattro is the industry's first choice in gas detection.

Design simplicity

The most distinct feature of the GasAlert Quattro is its easy to read display and gas indicators. The unit houses a large LCD display that provides constant visual confirmation of operation, gas monitoring, and compliance. The easy to read screen largely displays real time gas concentrations for H2S, CO, O2, and combustible gases. Each gas alarm set point is fully user adjustable. The unit also features a simple intuitive one button operation that minimizes training costs and requirements. With the touch of a button, users can operate a variety of standard features, including standard operating language in English, Spanish, French, German, and Portuguese.

Standard features

Like many BW Technologies by Honewell products, the GasAlert Quattro features a triple alarm system to alert users of hazardous atmospheric conditions. Wide ultra-bright alarm bars that are visible at multiple angles and when stored in pockets, audible alarms of over 95 decibels, and a high intensity vibrating alarm ensure that workers will be appropriately alerted regardless of the working conditions or sensory impairments. On activation, the GasAlert Quattro will automatically perform a variety of tests including sensor integrity, circuitry, battery, and alarm functioning. Additionally, the unit performs continuous monitoring on sensor and battery functioning to ensure the integrity and reliability of the device. For quick use and low maintenance, the GasAlert Quattro is equipped with an interchangeable and fully rechargeable battery pack. The unit may also be powered by an alkaline pack of 3 AA batteries.

To ensure constant security, each unit is equipped with IntelliFlash that provides continuous confirmation of the unit's operation. This particular series utilizes a flashing green LED. Users and safety managers are constantly apprised of the safety of their workers and the functioning of their security devices.

Powered by SureCell Sensors

Utilizing the most advanced technology available, Honeywell's SureCell Sensor is a revolution in electrochemical technology. The patented cell technology is designed to detect a wide range of toxins while maintaining a resistance to common industrial gas interference errors. This focus on detection integrity improves sensor performance and reliability.

Compatibility, options, and accessories

For easy calibration and bump testing, the GasAlert Quattro is fully compatible with BW's MicroDock II automatic test and calibration system. Users can customize their GasAlert Quattro with additional accessories including a carrying holster, auxiliary filter, and vehicle attachment. The unit is also capable of complete datalogging and record keeping.


GasAlert Quattro is highly transportable weighing between 11 and 12 ounces, depending on the attached battery pack. The gas detector also features a long shelf and battery life. Users can expect up to 14 hours of battery life with the AA battery pack and up to 18 to 20 hours with the rechargeable battery pack. A 2 year warranty is standard with every GasAlert Quattro purchase.
