AirTrack-i Iodine Monitoring Station with automatic cartridge changer and on-line spectrometric analysis

Application

AirTrack-i system display will allow to control and monitor the following parameters: Programmed Parameters:

• Flow-rate (m³/h)
• Sampling time (d, h, min, s)
• Data period (min)
• Measuring time (h, min, s)

Actual values:

• Flow-rate (m³/h)
• Normalized Flow-rate (m³/h) (In temperature 25°C)
• Cartridge (actual cartridge number)
• Step (actual step number)
• Sampled volume (m³)
• Normalized Sampled volume (m3) (In temperature 25°C)
• Dpressure (mBar - pressure drop through the cartridge)
• Inlet Air temperature (°C )
• Sampling time (h, min, s)
• Elapsed time (h, min, s)

Status Information
