Guard-633 H2S Detector & PT299 Combustible Gas Leak Detector, Dual-Gas Detection Kit for Hydrogen Sulfide and Flammable Gases, Fast Response & Triple Alarm System, for Industrial and RV Safety

The Guard-633 and PT299 form a professional-grade gas detection combo designed to protect you from two of the most dangerous types of gas hazards—hydrogen sulfide and flammable gases. The Guard-633 offers fast, accurate H₂S detection with triple alarms, adjustable thresholds, and explosion-proof protection, making it ideal for industrial and confined space use. Meanwhile, the PT299 excels at pinpointing combustible gas leaks in homes, RVs, or around gas appliances, thanks to its extendable sensor rod and visual + audible alarms. Whether for industrial monitoring or home safety, this bundle provides comprehensive, real-time protection for technicians, DIYers, and everyday users.

• Dual-Gas Safety Set: The Guard-633 precisely detects hydrogen sulfide (H₂S) with a high-performance sensor, while the PT299 quickly locates leaks of methane, propane, and other combustible gases. This dual-detector bundle provides essential protection for industrial workers, homeowners, and RV users against both toxic and explosive gas risks
• Rapid Detection with Visible Alerts: Guard-633 responds to H₂S in just 0.5 seconds and features a bright display, loud buzzer, and vibration alert. Likewise, PT299 detects combustible gases in 0.5 seconds and shows rising bar graphs with a red screen and buzzer when gas levels increase. Both detectors help users take swift action before hazards escalate
• Reliable and Portable: The Guard-633 is explosion-proof, dustproof, and water-resistant, with a clip-on design for easy wear. The PT299 features a retractable rod for reaching narrow or hard-to-access leak points. Both devices are compact, rugged, and built for safety on the go
• Long Battery Life and Auto Functions: Guard-633 runs continuously for up to 7 days on a single 5-hour charge, with real-time battery level and low battery alerts. PT299 is powered by two AAA batteries, includes auto shut-off, and starts with a 30-second warm-up countdown for accurate operation
