Description Overview GAOTek Carbon Monoxide Gas Analyzer is a portable 4 gas monitor. It is easy to carry and can detect 2, 3 or 4 different gases at the same time. The commonly is for LEL, O2, H2S, CO. This gas monitor is widely used in the world as its special advantage. Features 4 multi gases can be free combination (like: LEL, O2, H2S, CO, etc.) 2.4 in (60.96 mm) color LCD screen More than 1000 date storage per passage Easy operate, Energy saves AC and USD recharge Test function itself when power on Temperature and o’clock show Language: English and Chinese Technical Specifications Detecting Gas LEL, O2, H2S, CO, customized Alarm type Visible, Audible, Vibrating Display 2.4 in (60.96 mm) color LCD Color Black Language English Detected Gas Measuring range Resolution Respond Time Sensor service life CO 0 ppm to 1000 ppm 1 ppm ≤20 s 2 years to 3 years O2 0% to 30% VOL 0.1% vol ≤20 s 2 years to 3 years O3 0 ppm to 10 ppm 0.1 ppm ≤30s 2 years to 3 years H2S 0 ppm to 100 ppm 1 ppm ≤30 s 2 years to 3 years H2 0 ppm to 1000 ppm 1 ppm ≤30 s 2 years to 3 years CL2 0 ppm to 20 ppm 0.1 ppm ≤30 s 2 years to 3 years NH3 0 ppm to 200 ppm 1 ppm ≤30 s 2 years to 3 years SO2 0-20ppm 0.1 ppm ≤30 s 2 years to 3 years NO 0 ppm to 250 ppm 1 ppm ≤30 s 2 years to 3 years NO2 0 ppm to 20 ppm 0.1 ppm ≤30 s 2 years to 3 years CH2O 0 ppm to 50 ppm 0.01 ppm ≤30 s 2 years to 3 years HCL 0 ppm to 20 ppm 0.1ppm ≤30 s 2 years to 3 years HCN 0 ppm to 20 ppm 0.1 ppm ≤30 s 2 years to 3 years ETO 0 ppm to 100 ppm 1 ppm ≤30 s 2 years to 3 years CLO2 0 ppm to 10 ppm 0.1 ppm ≤30 s 2 years to 3 years CO2 0% to 5.00% vol 0.01% vol ≤30 s ≥5 year Combustible gas 0% to 100% LEL 1% LEL ≤30 s 3 years to 5 years Dimensions 6.14 in x 3.26 in x 1.88 in (156 mm x 83 mm x 48 mm) Weight 0.66 lb (300 g)
