ls25
the ls25 laser analyzer selectively measures the concentration of up to two sample components.the laser operates according to theprincipleofsingle-linespectroscopy. for measurement purposes a single absorption line is selected from the gas to be measured in the near infrared spectral range, at which no cross-sensitivity fromothergasesoccurs. theabsorption line is scanned and the receiver located opposite detects the absorption caused by the sample gas and calculates the gas concentration from this.
ls25激光分析仪可选择测量最多两种样品组分浓度。激光以单线光谱学原理为基础。测量时，在近红外光谱范围内测量的气体中选择一条单吸收线，此时不会发生来自其它气体的交叉林敏度。对该吸收线进行扫猫，安装在对面的接收器会检测到样气产生的吸收作用，并据此计算气体浓度。
the laser analyzer module consists of a transmission and receiver unit which can be used on ducts with a diameter of 0.5...6 m.dependingontheapplication, process pressures of 10 bar and temperatures up to1500 °c can be achieved.
浓度该激光分析仪模块配备有一个收发装置，能在管径为0.5...6 m的管道上使用。在实际应用中，过程压力最高可达10 bar，温度最高可达1500°c。
multianalyzer systems allow the combination of up to four analyzer modules from the product range.
多组分分析系统最多可以组成同一种产品系列中的四种分析模块。

calibration标定
 calibration takes place either via a built-in flow cell or a separate calibrating cell.
 标定即可通过内置流动分析池也可通过独立的标定池进行。
