air quality test instruments portable digital Carbon dioxide gas co2 analyzer capnometer

As colorless, tasteless and odorless gas under normal temperature, with the chemical formula of CO2 and formula weight of 44.01, carbon dioxide is one of the oxycarbide, whose common name is carbon dioxide gas, and it is also carbonic anhydride. It is a colorless and tasteless gas under normal temperature, is slightly larger than the air in density, and slightly soluble in water to generate carbonic acid. The solid carbon dioxide is commonly known as dry ice, which can absorb a larg eamount of heat during sublimation, therefore it is used as refrigerant, for artificial rainfall, and making smog on the stage,for examples. Carbon dioxide is the essential raw material in photosynthesis of green plants, and is usually used as fertilizer in the greenhouse.

Generally, 0.03% carbon dioxide is contained in the air;however, its content has sharply risen in recent years due tohuman activities (such as combustion of fossil fuel), resulting ingreenhouse effect, global warming, glaciers melting and sea-levelise, etc. The Kyoto Protocol aiming at curbing carbon dioxideexcessive emission has taken effect, which is hopeful to curbgreenhouse effect via promoting international cooperation. 

The carbon dioxide tester applies to the continuous online detection and site sound-light alarm of carbon dioxide concentration in various industrial environments and specialenvironment, which functions as early warning for operationsafety on the dangerous site. Using the imported electrochemicalsensor and microcontroller technologies, the instrument isfeatured by stable signal, high precision and good repeatabilityand other merits, and its explosion-proof connection mode appliesto various dangerous sites. It can provide 24-hour continuousreal-time monitoring of indoor carbon dioxide concentration,display date, detection time, temperature and humidity data on the detection site automatically. The instrument is compatible with various control alarms, PLC, DCS and other control systems,which can realize site alarm, remote monitoring and alarm function at the same time.
