Carbon monoxide detector, toxic gas detector, CO gas detector, audible and visual alarm AS8700A, battery-free

General descriptionThe carbon monoxide (CO) gas detector is a portable device designed to detect gaseous carbon monoxide. It continuously monitors the concentration of CO in the environment, triggering an alarm and light when the concentration reaches a predefined level. This high-precision portable CO tester is compact and lightweight, making it easy to transport and use. It is widely used in various industries including petroleum, chemistry, coal, metallurgy, paper, fire safety, telecommunications, food, and textiles.Technical specificationsBrand: SMART SENSORColor: Black and OrangeMaterial: ABS plasticSensor type: Stabilized specific electrochemical (CO)Gas detection: Carbon monoxide (CO)Temperature measurement: Ambient temperatureDisplay unit: CO in ppm, temperature in ℃ / ℉Measurement range: CO: 0 ~ 1000 ppm, Temperature: 0 ~ 50 ℃ / 32 ~ 122 ℉Resolution: CO: 1 ppm, Temperature: 0.1 ℃ / 0.1 ℉Accuracy: CO: ± 5% or ± 10 ppm, Temperature: ± 1.5 ℃Response time: Alarm: Sound and light alarmAlarm point: 24 ppm (adjustable)Operating temperature: 0 ~ 50 ℃Relative humidity: 1% ~ 99%Storage temperature: -30 ~ 60 ℃Item dimensions: 135 * 50 * 35 mm / 5.31 * 1.97 * 1.38 in (L * W * H)Item weight: 89 g / 3.13 ozPackage dimensions: 215 * 150 * 50 mm / 8.46 * 5.91 * 1.97 in (L * W * H)Package weight: 127 g / 4.48 ozOther informationBattery type: 3 AAA 1.5V alkaline batteries (not included)Package includes: 1 * Carbon monoxide meter, 1 * User manual
