Smart Sensor Ar8100 Handheld Precision Oxygen Detectors O2 Meter

Smart Sensor AR8100 Handheld Precision Oxygen Detectors O2 Meter      Features& 65306;     A gas detector is a device that detects the presence of gases in an area, often as part of a safety system. 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. A gas detector can sound an alarm to operators in the area where the leak is occurring, giving them the opportunity to leave. This type of device is important because there are many gases that can be harmful to organic life.     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.       Specifications& 65306;                       Detection of Gas       Oxygen(O2;)                 Measuring Range       0~25%                 The Principle of Sensor       Electrochemical principle, life for two year                 Resolution       0.1%                 Accuracy       ---                 Response Time       <50 sec                 Recovery Time       <50 sec                 To Alarm       Acoustic,Otical double alarm, can set thealarm value,an alarm sound is divided into 80dB                 Operating Temperature       -20~50C                 Operating Humidity       0-95%RH(Non Gel)                 Temperature Measuring                                    Packing Information& 65306;                   Power       3.7V li-battery                 Product Net Weight       148g                 Product Size       159*66*31mm                 Packing       Gift Box
