Feature:1. The multifunctional gas detector adopts ABS material, which has highstrength engineering plastics, good shock resistance, water resistance, dust resistance and explosionproof properties.2. The back has a clip stainless steel crocodile buckle, which can be fixed on the outside of the tooling, and the special tooth mouth is firmly clamped and not easy to fall off.3. Equipped with 1800mAh highcapacity battery, up to 10 hours, satisfying longterm workers who go out. And the portable detector will alert with three kinds of alarms: sound, light, and vibration, with large capacity and recording the alarm value.4. Support high sensitivity and accurate measurement. Oxygen, carbonic oxide, sulfuretted hydrogen and explosive gas can be detected accurately. Detection error is less than 5% FS and response time is less than 30s.5. Can be widely used in petroleum, metallurgy, agriculture, chemical industry, oil refining, fire prevention, and effective prediction to ensure a safe environment. Small size and unique clip design make is easy to carry.6. Imported chip has a sharp sense of air, adopts advanced gas sensor chip, professional team research and development and production has better sensitivity and more accurate measurement.Specification:Item Type: Gas Detector.Material: ABSEasy to Carry:The gas monitor is small in size, unique clip design and convenient for users to carry.Wide Range of Uses:It can be widely used in petroleum, metallurgy, agriculture, chemical industry, oil refining, fire prevention, which can effective predict to ensure a safe environment.Battery: 3.7V Lithium Battery 1800mA (Battery Included)Plug Voltage: 100-240VWaterproof Level: IP65 LevelSupport Detection Gas: Combustible Gas, Oxygen, Hydrogen Sulfide, Carbon Monoxide (EX, H2S, CO, O2)Display Error: 5%FSResponse Time: T30SMeasuring Range: 0-100%LEL, 0-30vol%, 0-1000ppmWorking Temperature: -20-50Conventional Gas Detection Range:Gas type Range Low Alarm Point Alarm ResolutionEX 0-100%UEL 20%LHL 50%LHL 1%LHL H2S 0-100PPM 10PPM 35PPM 1PPMCO 0-1000PPM 50PPM 150PPM 1PPMO2 0-30%VOI 19.5%VOI 23.5VOI 0.1%VOPackage List:1 x Aluminum Box1 x Detector1 x Fixing Frame1 x Plug1 x USB Cable1 x Manual
