ZX7M-ZRE infrared gas analyzer can sample gases NO, SO2, CO2, CO, CH4 and O2 concentration is measured. NO, SO2, CO2, CO, CH4 single-beam method of non-dispersive infrared (NDIR) measurement, O2 electrochemical or zirconia-style-type measure. Can be measured simultaneously, including O2, including up to five components. As a small design, measuring devices to help save space. Moreover, due to adopt a single beam mode, to maintain outstanding performance. Most suitable for waste incinerators, boilers and other combustion exhaust measurements, as well as for various industrial furnace gas measurement systems analysis component. 
 Feature 
 1 compact and lightweight 
 Dimension 133 × 483 × 418mm (H × W × D), weight 8kg, simultaneous measurement of up to 5 components. 
 (2) maintenance 
 Single beam method for measuring parts of the structure is simple, but without the optical balance adjustment, maintenance is easy. 
 3 simple operating performance 
 By using a large LCD screen display, clear eye-catching, easy to operate even more clear. 
 4. Improve the function of 
 Additional accessories can be selected automatically by the correction control, the lower limit on the concentration of alarm, remote range switching input, signal output range identify the rich features.

 Single-beam gas analyzer. 1 analyzers at the same time continuous measurement of 5-component gas components, the most suitable for measuring incinerator, combustion exhaust, industrial furnaces such as NOX, SO2, CO, CO2, CH4, O2 gas concentration. Maximum of 5 components of the continuous measurement of gas concentration at the same time. Using mass-flow, almost independent of other gases. Use clear and easy to see the large LCD display that can simultaneously monitor changes in the concentration of 5 components. Single-beam type, compact, and easy maintenance. Excellent long-term stability. Using a large LCD screen, clearer eye-catching, easy to operate. Can be automatically corrected, the lower the concentration of alarm and remote range switching. Almost free from water interference effects. Magnetic oxygen analyzer with built-in or sold goods zirconia oxygen analyzer two kinds of measuring instruments of O2. 
 NO :0-2500PPM, SO2 :0-3000pPPM, CO2 :0-25% CO: 2500Ppm
