EM-21/CO2二氧化碳分析仪
EM-21/CO2二氧化碳分析仪产品介绍（中文）
EM-21/CO2是一款便携式红外二氧化碳气体检测仪，采用双波束红外测量原理，能够快速准确地检测环境中的二氧化碳浓度。该仪器具有0~50000ppm的宽量程范围，分辨率可达1ppm，适用于燃气站、化工厂、温室、酒店等各类密闭或半密闭空间的CO2浓度监测。仪器设计轻巧（尺寸113×60×24mm），内置充电电池可连续工作10小时，操作简便且无需频繁校准。其核心传感器采用非分散红外技术（NDIR），通过检测CO2分子对特定波长红外光的吸收特性实现浓度测量，避免了电化学传感器的交叉干扰问题。显示屏直接显示实时浓度数值，并具备声光报警功能，当浓度超标时可及时提醒用户。仪器外壳采用工程塑料材质，具有良好的防震和防水性能，适合在复杂工业环境中使用。161927
EM-21/CO2 Carbon Dioxide Analyzer (English)
The EM-21/CO2 is a portable infrared CO2 gas detector utilizing dual-beam IR measurement technology for precise environmental monitoring. With a detection range of 0-50,000ppm and 1ppm resolution, it reliably measures carbon dioxide levels in diverse settings including industrial plants, greenhouses, and public venues. The compact design (113×60×24mm) incorporates a rechargeable battery providing 10 hours of continuous operation. Its NDIR sensor detects CO2-specific infrared absorption without cross-sensitivity to other gases, ensuring measurement accuracy. The instrument features real-time digital display with audible/visual alarms when concentrations exceed user-defined thresholds. The rugged housing provides shock resistance and splash protection for field applications. Simple one-button operation and minimal maintenance requirements make it suitable for routine air quality assessments in energy facilities, agricultural sites, and commercial buildings. The analyzer automatically compensates for temperature variations to maintain consistent performance across operating conditions.281927
