LS25
The LS25 laser analyzer selectively measures the concentration of up to two sample components.The laser operates according to the principle of single-line spectroscopy. 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 from other gases occurs. The absorption line is scanned and the receiver located opposite detects the absorption caused by the sample gas and calculates the gas concentration from this.
LS25激光分析儀可選擇測量zui多兩種樣品組分濃度。激光以單線光譜學原理為基礎。測量時，在近紅外光譜范圍內測量的氣體中選擇一條單吸收線，此時不會發生來自其它氣體的交叉林敏度。對該吸收線進行掃貓，安裝在對面的接收器會檢測到樣氣產生的吸收作用，并據此計算氣體濃度。
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. Depending on the application, process pressures of 10 bar and temperatures up to1500 °C can be achieved.
濃度該激光分析儀模塊配備有一個收發裝置，能在管徑為0.5...6 m的管道上使用。在實際應用中，過程壓力zui高可達10 bar，溫度zui高可達1500 °C。
Multianalyzer systems allow the combination of up to four analyzer modules from the product range.
多組分分析系統zui多可以組成同一種產品系列中的四種分析模塊。

Calibration
標定
Calibration takes place either via a built-in flow cell or a separate calibrating cell.
標定即可通過內置流動分析池也可通過獨立的標定池進行。
