JNL-261 infrared analyzer
JNL-261 infrared analyzer
JNL-261 uses infrared ray for gas analysis. It is based on the concentration of the components to be analyzed, the absorbed radiation energy is different, the remaining radiation energy makes the temperature in the detector rise differently, and the pressure on both sides of the moving film is different, thus generating an electrical signal of the capacitance detector. In this way, the concentration of the components to be analyzed can be measured.
Product features
