SMART SENSOR AS8900 4 in 1 Combustible Gas Detector Analyzer Handheld Multi-Gas Monitor Gas Detector O₂ CO H₂S Analyzer Explosion-Proof ( Item#: E26001 )

Features:
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 epletion, 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.
While many of the standard gas detector units were originally fabricated to detect one gas, modern multifunctional or multi-gas devices are capable of detecting several gases at once. Some detectors may be utilized as individual units to monitor small workspace areas, or units can be combined or linked together to create a protection system.
Widely used in ships, mines, petroleum exploitation, chemical industry, gas pipeline, tunnel construction, coal, metallurgy, paper making, fire fighting, municipal administration, textile and other industries.
