    • Compensation and calibration method for a nondispersive infrared gas analyzer which includes an infrared source of radiation, a measuring path, a reference path, modulation devices, a detector for differential pressure measuring, comprises the following steps: first and prior to measurement, the reference gas having a variable basic concentration in the measuring component is forced through the reference branch and through the measuring branch and the detector is set to a zero position; next a dual calibration chamber is placed into the two reference paths while both of them are still passed through by the reference gas, one of the calibration chambers including a particular concentration in the measuring gas the other one lacking that measuring gas; now the sensitivity and amplification of the detector that obtains as a result of changes in the radiation on account of placing the calibration chamber into the reference and measuring path is adjusted, whereupon the calibration chamber is removed, reference gas still is passed through the reference chamber, while measuring gas now flows through the measuring chamber.
    • 包括红外辐射源,测量路径,参考路径,调制装置,差压测量用检测器的非分散型红外线气体分析仪的补偿和校准方法包括以下步骤:在测量之前和之前,参考气体 在测量部件中具有可变的基本浓度被迫通过参考分支并通过测量分支,并且检测器被设置为零位置; 接下来,将双重校准室放置在两个参考路径中,同时它们仍然被参考气体通过,其中一个校准室在测量气体中包括特定的浓度,另一个校准室中缺少该测量气体; 现在调整由于将校准室置于参考和测量路径而由辐射变化而获得的检测器的灵敏度和放大率,从而校准室被移除,参考气体仍然通过参考室 而测量气体现在流经测量室。
