TDLS(조절 가능 다이오드 레이저 분광법) 원리에 기반하여, GM700은 NH3, HF, HCl 또는 H2O와 같은 다양한 가스 성분을 특정 광 흡수 특성을 통해 측정합니다. GM700은 뛰어난 신뢰성과 정확성 그리고 매우 짧은 응답 시간이 특징인 레이저 가스 분석기입니다. 현장 측정 방식으로 프로세스 제어와 배출가스 모니터링에서 가스 농도를 신속하게 측정하는 데 특히 적합합니다.

The GMK03 gas test unit is used to test the linearity of the measurement results of gas analyzers as required for a metrological quality test (e.g. for QAL2, QAL3). For this purpose, the GMK03 gas test unit can simulate several graded test gas concentrations with a single (suitable) test gas.
With our broad range of solutions Endress+Hauser has proven applicability in the entire power generation process, from gas flow to combustion efficiency to emissions monitoring.
