The carbon monoxide gas detector is a portable detector for detecting carbon monoxide(CO) gas. It can continuously monitor the CO gas concentration in the surrounding environment, once the gas concentration reaches the level of the alarm, the alarm will light up and vibrate. <br>It is widely used in petroleum, chemical, coal, metallurgy, paper, fire, municipal, telecommunications, food, textile and other industries. <br><br><strong>Features:</strong> <br>Appearance of light and novel, easy to carry and operate. <br>Menu operation interface, battery power. <br>Battery real-time display, automatic shutdown with low voltage. <br>Sound, light and vibration alarm. <br>Professional and accurate measurement. <br>Large LCD display and ℃/℉ switch. <br><br><strong>Specification:</strong> <br>Sensor: Electrochemical Principle <br>Test Gases: Carbon Monoxide (CO) <br>Temperature Measurement: Ambient Temperature     <br>Display Unit: CO: PPM <br>         Temperature: ℃/℉          <br>Measurement Range: CO: 0 ～ 2000PPM     <br>             Temperature: -15～50℃ / 5～122℉      <br>Resolution: CO:1ppm                                              <br>        Temperature: 0.1℃ / 0.1℉ <br>Accuracy: CO:±5%FS                                                <br>       Temperature: ±1.5℃ <br>Response Time: T90 &lt;30s                 <br>Alarm: Sound alarm,light alarm,vibration alarm   <br>Alarm Point: low alarm point: 35ppm                <br>         high alarm point: 70ppm            <br>Battery Type: 3 * AAA 1.5V Alkaline Batteries (NOT Included) <br>Operating Temperature: -15～50℃ / 5～122℉      <br>Operation Humidity: 15%～95%RH (non condensation) <br>Item Size: Approx. 12 * 6.5 * 2.5cm / 4.7 * 2.5 * 1.0in (L * W * H) <br>Item Weight: Approx. 95.4g / 3.4oz <br>Package Size: Approx. 22.5 * 11.1 * 5.5cm / 8.9 * 4.4 * 2.2in (L * W * H) <br>Package Weight: Approx. 228g / 8.0oz <br><br><strong>Package List:</strong> <br>1 * CO Detector <br>1 * User Manual <br>1 * Protection Bag
