Product description
Why choose the TOPTES S2 Multi Gas & Carbon Monoxide Detector?
Combustible gases and CO often occur together. S2 Multi combines both into one compact device. Featuring rapid response, an extendable probe, audible & visual alarms, and Type-C charging, it enables more thorough safety inspections.
Why does the detector require a warm-up period before use?
Gas sensors require a brief warm-up period to reach their optimal operating temperature and stabilize the internal sensor circuitry, ensuring accurate readings and preventing false alarms. (Note: Always turn on the device in fresh, clean air.)
Can the S2 Multi be used for continuous monitoring?
No. The S2 Multi is designed as a portable spot-checking tool for locating leaks and assessing immediate hazards. It is not intended for continuous, 24/7 fixed monitoring.
Why does only the combustible gas end have an extendable probe, while the carbon monoxide end does not?
Combustible gas leaks typically originate from specific, narrow points, making an extendable probe essential for pinpointing the source. In contrast, CO disperses rapidly, requiring broad ambient detection rather than focused pinpointing.
2-in-1 Gas and Carbon Monoxide Detector: TopTes S2 Multi detects natural gas, propane, other combustible gases, and carbon monoxide simultaneously. Cover two common household safety risks with one device. Ideal for home, RV, basement & camping safety
Extendable Probe：The combustible gas leak detector features a 6.5-inch / 16.5 cm extendable probe that helps you inspect narrow gaps and difficult-to-reach locations where natural gas leaks may occur
Clear LCD Display with Dual Alarms：This Gas & CO alarm has a clear LCD color display with real-time readings for combustible gases (0.1-20% LEL) & carbon monoxide (0-999 PPM). Visual & audible alarms trigger at set thresholds to help you spot hazards fast
User-Friendly Functions: This gas and carbon monoxide detector features a rechargeable battery, one-touch alarm mute function, adjustable backlight brightness (High/Low), and an APO auto power-off function that can be disabled for flexible operation
What You Get: S2 Multi combination gas and carbon monoxide detector, a protective case, a user manual, and a charging cable. NOTE: Allow 30 seconds of warm-up in clean air before starting detection
