【POWERFUL FUNCTIONS】Portable Carbon Monoxide Meter can continuously monitor the CO concentration in the surrounding environment. Ensure excess CO gas is detected and operators are alerted to take action. And it has 4 modes, which can be easily switched according to the working environment.

【ACCURACY & DURABILITY】 The high-precision Carbon Monoxide Detector has an automatic calibration function. The measurable CO concentration range is 0~1000PPM (accuracy 1PPM); when the CO gas concentration reaches the alarm level, the sound and light alarm will work. It can measure the ambient temperature with two temperature units (℃ and ℉) (temperature range: 0~50℃/32~122℉). Made of high-quality ABS engineering plastic, it feels comfortable and durable. The sensor life is up to 3 years.

【PRACTICAL DESIGN】Handheld Carbon Monoxide Meter is small in size (5.31 X 1.97 X 1.38 in) and light in weight (3.14oz/0.17 lb), making it easy to carry and operate. The high-definition LCD backlit screen makes it easy to read even at night. In addition, you can also set whether to enable automatic shutdown (when the automatic shutdown function is enabled, if there is no operation within 10 minutes, it will automatically shut down to save power).

【APPLICATION RANGE】The Carbon Monoxide Tester has the characteristics of wide measurement range, high measurement accuracy, small size, convenient carrying, and operation. It is widely used in coal, oil rig, textile, chemical, metallurgy, papermaking, fire fighting, municipal and other industries.

【SHOPPING WITH CONFIDENCE】The product is guaranteed for 365 days from the time of purchase. If you are not satisfied with the product or have any questions, please feel free to contact us, we will reply and solve your questions within 24 hours.

PROFESSIONAL TOOL: The gas detector is a device that detects the presence of CO gases in an area, often as part of a safety system. The professional detector can continuously monitor the CO gas concentration accurately in the surrounding environment. This type of equipment is used to detect a gas leak and interface with a control system so a process can be automatically shut down.

POWERFUL FUNCTION: Sound alarm works when CO gas concentration reaches the level of the alarm. The concentration of alarm value can be freely set. Auto shut off in 10 minutes without any operation. With a wide measuring range, the ambient temperature can be measured in 2 temperature units (°C and °F).

HGIH QUALITY：This CO detector has a large LED backlight screen that allows users to easily cope with harsh environments such as darkness, making it easy to read and free users from time and place constraints. Adopt of ABS engineering plastics with high toughness, wear-resistance and stability, with a low power consumption and high precision.

HANDHELD SIZE: The CO gas meter is compact and lightweight, professional designed to fit comfortable in your palm，easy to carry and operate.

WIDELY APPLICABLE: The Gas detectors can be used to detect combustible, flammable and toxic gases, and oxygen depletion, etc. This type of device is widely used in industry and can be found in locations, such as on oil rigs, to monitor manufacture processes and emerging technologies such as photovoltaic. They may also be used in firefighting.

【Fast and Accurate Detection】The carbon monoxide detector is built-in advanced electrochemical CO sensor that provides high-precision alarms for fast and accurate detection of carbon monoxide levels. When the carbon monoxide concentration exceeds the specified value, an alarm warning of more than 85 decibels will be issued. To ensure complete protection, be sure to place one on every floor of your home and in every bedroom.

【Wide Adaptability】The carbon monoxide detector is suitable for all places where carbon monoxide may be produced, such as your home kitchen, bedroom, bathroom, warehouse, hotel, car, parking lot or barbecue time! The portable carbon monoxide detector is powered by 2*1.5V AAA batteries (not included), which is easy to use, just one test/reset button.

【LCD Digital Display and LED Indicators】The carbon monoxide detector has an LCD digital display that displays real-time CO levels, allowing you to see any significant changes in CO levels, and can display battery life, prompting you to replace batteries.The intuitive LED indicator can clearly inform the working status of the CO alarm detector: the green LED indicates normal operation, the red LED indicates the alarm status, and the yellow LED indicates the fault.

【Portable and Easy to Install】The carbon monoxide detector is easy to install without rewiring. It can be mounted on any wall or ceiling, as well as in a car. This CO detector includes mounting brackets, screws and anchors, and comes with 3M adhesive. It is not only an ideal carbon monoxide quotation device for home use, but also a must-have for car or travel.

【Quality Assurance】All CO alarms have been rigorously tested, and meet UL standards. If you have any questions about our CO detectors, please feel free to contact us. (Note: When you test the detector, please do not blow the hole directly with gas.)
