SCY-2A CO₂气体测定仪是一款由上海昕瑞仪器仪表有限公司生产的便携式气体检测设备。该仪器能够同时测定混合气体中的氧气（O₂）和二氧化碳（CO₂）的百分含量。它采用交直流两用设计，配备镍氢充电电池、免维护充电器和内置抽气泵，适合在野外或移动环境中使用。

该仪器的测量范围为：O₂ 0-99.9%，CO₂ 0-99.9%。其精度在不同浓度区间有明确的误差范围，例如CO₂在0-50%时误差为±3.0%，50-99.9%时误差为±5.0%。它还具备低电压报警功能，采用低功耗的液晶显示器，读数方便。

SCY-2A的体积为208×190×80mm³，重量仅为2.1kg，随机配有铝合金包装箱，便于携带和使用。它适用于学校、科研、工业、环保、医学、化工、农业等多个领域，尤其适合用于蔬菜、粮食、烟草、果品的保鲜和气调储藏过程中的气体浓度测定。

The SCY-2A CO₂ Gas Analyzer is a portable gas detection device produced by Shanghai Xinrui Instrument Co., Ltd. This instrument is capable of simultaneously measuring the percentage of oxygen (O₂) and carbon dioxide (CO₂) in mixed gases. It features a dual power supply design, equipped with nickel-hydrogen rechargeable batteries, maintenance-free chargers, and an integrated suction pump, making it suitable for use in the field or mobile environments.

The measurement range of the SCY-2A is 0-99.9% for both O₂ and CO₂. The precision of the instrument is clearly defined for different concentration intervals. For example, the error for CO₂ is ±3.0% for concentrations between 0-50%, and ±5.0% for concentrations between 50-99.9%. It also has a low voltage alarm function and uses a low-power LCD display for easy reading.

With dimensions of 208×190×80mm³ and a weight of only 2.1kg, the SCY-2A is highly portable and comes with an aluminum alloy case. It is suitable for a wide range of applications, including schools, research, industry, environmental protection, medicine, chemical industry, and agriculture. It is particularly ideal for measuring gas concentrations during the preservation and controlled atmosphere storage of vegetables, grains, tobacco, and fruits.
