Professional multi-gas detector with alkaline battery for detecting LEL, O2, H2S, and CO in confined spaces and hazardous areas. Features SureCell technology, rugged concussion-proof design, and comprehensive alarm system.
The BW GasAlert Quattro is a professional-grade multi-gas detector designed for reliable detection of four critical gases in industrial environments. This model features an alkaline battery power system and comes equipped with filtered LEL sensors alongside dedicated sensors for oxygen (O2) depletion, hydrogen sulphide (H2S), and carbon monoxide (CO). Ideal for confined space entry and hazardous area monitoring, this detector provides real-time gas concentration data with exceptional accuracy and reliability.
Built with durability in mind, the GasAlert Quattro features an integrated concussion-proof boot that protects the device from impacts and drops common in industrial settings. Despite its rugged construction, the unit remains lightweight and compact at just 338 grams, making it comfortable to wear and carry throughout extended work shifts. The bright yellow housing ensures high visibility on job sites, and the device operates effectively across a wide temperature range from -20°C to +50°C.
Equipped with SureCell sensor technology, this multi-gas detector offers enhanced resistance to common industrial cross-sensitive gases including methanol and ethanol, particularly in the CO and H2S sensors. The unit provides visual, audible (95 dB), and vibrating alarms with multiple alarm levels including Low, High, STEL, TWA, and Over Limit settings. With datalogging and event logging capabilities, comprehensive LCD display information, and full-function self-test capabilities, the GasAlert Quattro delivers professional-grade safety monitoring with minimal training requirements.
