EASY TO USE Switch on the gas detector in a clean air environment and wait for the beep signalling the detector is ready to use. Take the detector to the area where you want to check for gas leaks. If as soon as the internal sensor detects gas concentrations over 50ppm, the unit will indicate by illuminating the LEDs on the front of the detector and raise an audible alarm. The greater the presence of gas, the more LEDs will illuminate, and the alarm will sound more frequently.
TECHNICAL SPECIFICATIONS Sensor Gas-sensitive bulk semi-conductor. Reaction Sensitivity 50ppm (methane). Warm-Up Time Approx. 30 seconds. Reaction Time 2 seconds. Operating Conditions 0 C to 50 C (32 F - 122 F) 20 to 80% RH. Storage Conditions -10 C to 60 C (14 F - 140 F) 20 to 80% RH. Battery Life Approx. 3 hours. Power Supply 2 x 1.5V AAA alkaline batteries (included).
FEATURES This Gas Leak Detector has an internal sensor and a 100mm flexible probe, which facilitates gas detection. It detects gas concentrations in the air between 50ppm & 1000ppm. When gas is discovered visual and audible alarms are set off. An important feature is the sensitivity setting that can be set to high or low. The Gas leak Detector offers a quick sensing response, and it has auto power off function to preserve battery life.

How to rotate the screen When you receive the product and plug it into the socket, if the display screen is upside down, you can long press the "speaker" button to invert the screen 180 .
High-precision comprehensive detector The product is equipped with precision CO and combustible sensors, which are refreshed every 2 seconds and can quickly detect the surrounding CO values. The detection range is 0-999PPM, and the accuracy is 10%. The combustible sensor has a detection range of LV1-LV4 and an accuracy of 15% LEL; it can also be used as an indoor thermometer with a temperature range of -10 50 and an accuracy of 1.5 ; it can also be used as a hygrometer with a humidity range of 0% 95%RH and an accuracy of 5%RH.
HD display Not only can you intuitively view the carbon monoxide and combustible concentration values on the HD display, but you can also see the temperature and humidity conditions that you pay attention to daily, saying goodbye to the embarrassing situation of the small screen of traditional carbon monoxide and combustible detectors. At the same time, you can also intuitively view the concentration of multiple gases from one screen.
Intimate brightness design When you feel that it is very power-consuming to keep the HD screen on, you can choose to press the brightness key to adjust the brightness status. When you choose to turn off the screen brightness, the product will continue to monitor, and the indicator light will remind you every 5 seconds to inform you that the product is in normal monitoring status. If the carbon monoxide concentration value in the surrounding environment exceeds 50PPM or the concentration of combustible gas exceeds 5% LEL, the detector will quickly detect it and issue an alarm sound of more than 85dB to remind you.
Home Essentials & Travel Safety Essentials This plug-and-play portable carbon monoxide and combustible detector can make your travel safer when you are traveling, staying in a hotel, traveling in an RV. When you are worried that traditional carbon monoxide and combustible detectors need to replace batteries regularly and the small screen can hardly see the carbon monoxide and combustible concentrations, this four-in-one detector allows you to clearly see the carbon monoxide concentration, combustible gas concentration, temperature and humidity.
