The SUMRING KH168 offers these functions with a clear digital display. It monitors CO and combustible gas levels while showing temperature and humidity readings. Users can view key information on one screen and receive local warnings when an alarm condition occurs.
The KH168 uses AC 110–220V power and supports a 9V alkaline backup battery. It also features adjustable screen brightness, alarm volume controls, and a self-test button.
For distributors, wholesalers, contractors, and private-label brands, this multi-function detector offers a compact option for suitable indoor gas safety projects. SUMRING supports OEM and ODM inquiries based on customer requirements.
What Are the Main Features of This 5 in 1 CO and Gas Detector?
1. Five Functions in One Device
The KH168 combines CO detection, combustible gas monitoring, temperature display, humidity display, and audible and visual alarm functions.
This design helps users check several environmental readings through one unit. The 5 in 1 CO and gas detector does not claim to detect five different gases.
2. Carbon Monoxide Detection
The KH168 has a published CO detection range of 0–2000 ppm and a CO alarm concentration of 150 ppm.
CO is a harmful gas that cannot be identified by smell alone. The detector provides local warnings according to its specified alarm settings.
Buyers should verify the alarm response, sensor specifications, and relevant safety standards for their destination market.
3. Combustible Gas Detection
The detector monitors combustible gas concentration within a published range of 0–10% LEL. Its specified gas alarm concentration is 5% LEL.
LEL means Lower Explosive Limit. The target combustible gas and calibration conditions must be confirmed before installation.
Do not assume that every combustible gas detector is suitable for all gas types.
4. Digital Temperature and Humidity Display
The digital screen provides temperature and humidity readings alongside gas monitoring information.
The published temperature display range is 1–176°F, with a stated tolerance of ±4°F. The humidity display range is 0–99%, with a stated tolerance of ±5%.
These functions provide additional environmental information. They should not be treated as certified temperature or humidity alarm functions.
5. AC Power with 9V Battery Backup
The 5 in 1 CO and gas detector operates from an AC 110–220V supply and supports a 9V alkaline backup battery.
The backup battery can help maintain operation during a temporary mains power interruption, provided the battery is installed and has sufficient capacity.
The backup operating duration is not specified on the current product page.
6. Adjustable Display and Alarm Volume
The KH168 includes BRIGHTNESS and VOLUME controls. Users can adjust the screen intensity and alarm volume according to the available product settings.
The correct alarm sound setting must meet applicable project and safety requirements.
7. Self-Test and Visual Indicators
A dedicated self-test button supports routine functional checks. Green, yellow, and red indicators help users identify operating and warning states.
The published alarm description includes a flashing red indicator. Follow the product manual to understand the complete indicator sequence.

How Does the KH168 5 in 1 CO and Gas Detector Work?
The KH168 monitors carbon monoxide and combustible gas through its sensing system. It also measures and displays temperature and humidity. The device processes the readings and activates its local alarm when the specified gas alarm condition is met.
Step 1: Power On and Preheat
Connect the detector according to its approved power instructions. The published preheating countdown is 180 seconds. Follow the manual before relying on normal monitoring.
Step 2: Monitor CO and Combustible Gas
The detection system monitors the surrounding air for the supported gases. The published CO range is 0–2000 ppm, while the combustible gas range is 0–10% LEL.
Step 3: Display Environmental Readings
The digital display provides CO, combustible gas, temperature, and humidity information. This helps users review the reported conditions in one location.
Step 4: Activate the Gas Alarm
The published alarm settings are 150 ppm for CO and 5% LEL for combustible gas. When an alarm condition is reached, the detector provides audible and visual warnings.
Treat an alarm as a possible emergency. Move to a safe location and contact the appropriate emergency service. Do not ignore or disable an unexplained alarm.
Step 5: Support Backup Power
The 9V alkaline backup battery can support operation during a temporary AC power interruption. The actual backup duration depends on the battery condition and the approved configuration.
Step 6: Perform Routine Checks
The self-test button helps users check the supported warning functions. Regular inspection, cleaning, and battery maintenance should follow the manufacturer’s instructions.
What Should B2B Buyers Check Before Ordering?
The KH168 5 in 1 CO and gas detector may be considered for suitable indoor projects that require CO and combustible gas monitoring with a digital display.
Buyers should confirm the target combustible gas, alarm response, electrical supply, installation environment, and applicable local safety standards.
