FAQ kh168 CO & Gas & temperature & humidity detector

Q1: What does this detector monitor? A: It is a 4-in-1 device that monitors carbon monoxide (CO), combustible natural gas,
temperature and humidity simultaneously on one LCD screen.

Q2: What are the alarm thresholds? A: CO alarms at 150 ppm (range 0~2000 ppm). Combustible gas alarms at 5% LEL (range 0~10% LEL). When triggered, the red LED flashes and the buzzer sounds.

Q3: How is it powered? A: Plug-in design, AC 110-220V universal voltage. Static power ≤2W, alarm power ≤3W. A 9V battery backup allows continuous monitoring during power outages.

Q4: What does the LCD display? A: Real-time CO concentration in PPM, gas level in %LEL, temperature in °F (1~176°F, ±4°F), and humidity in %RH (0~99%, ±5%).

Q5: How do I test if the alarm works? A: Press the SELF-TEST button. The red light flashes and the buzzer beeps to confirm normal function. After plugging in, wait 180 seconds for preheat countdown before normal monitoring begins.

Q6: Can I adjust the volume and screen brightness? A: Yes. The VOLUME button adjusts or mutes the alarm sound, and the BRIGHTNESS button has 3 backlight levels.

Q7: What certificates can you provide? A: CCC certificate is available for the China market. CE, EN54, UL, UKCA and RoHS documents can be provided upon request for overseas projects.

Q8: What is the MOQ and do you offer OEM? A: MOQ is negotiable (typically 500 pcs for OEM). Samples are available. Custom logo, color box and multi-language manual are supported.
