Gas analyzer 700 LX CLD NOx

processfor pharmaceutical productsconcentration

Overview
The 700 LX CLD analyzer applies chemiluminescence (CLD) to determine NO and NOx concentrations in gas samples. In NO mode ozone reacts with nitric oxide to form NO2, O2 and light proportional to NO2; the emitted light is detected by a photodiode. In NOx mode NO2 is reduced to NO to provide total NOx measurement.

Features and benefits

• Measurement range: 3 ppm to 3,000 ppm full scale (higher ranges on request)
• Three measurement modes: NO, NOx and NO/NO2/NOx
• Automatic calibration and autoranging
• Fast response time for process control
• Robust Linux-based operating system
• Electronic control of sample and ozone flows
• No vacuum pump required
• Comprehensive diagnostics and status reporting

Options

• Internal sample pump
• Internal calibration solenoid valves
