Advantages

Advantages

 N/A Advantages at a glance:
  • Permanent, highly precise residual oil measurement (oil vapor) with PID sensor (photo-ionic-detector)
  • Ideal for mobile measurement: The PID sensor is ready for measurement within about 30 minutes
  • Measuring results with long-term stability due to automatic zero point calibration. The integrated mini catalyst reliably generates a defined reference gas for zero point calibration
  • In contrast to measuring systems which generate the “zero air” or reference gas by means of active carbon filters and which are therefore dependent on the ageing and saturation of the active carbon filters, the mini catalyst generates the “zero air” without ageing or wear. There is no change of active carbon filters necessary
  • Easy sampling via PTFE hose or stainless steel pipe
