- Model PEN3 - Portable Electronic Nose


PEN3 is the essential electronic nose for food and pharmaceutical industries (quality control purposes as well as for environmental monitoring (recognition of emission sources).  It is a small, fast and robust identification system for gases and gas mixtures. Gas detection is performed with an array of gas sensors. Single compounds or mixtures of gases can be identified after a training step by using the pattern generated by the sensors.

Intelligent chemical sensor for identification of gases and vapours

PEN3 is based on a metal-oxide gas sensor array in a small measurement chamber.
Using a specific dilution technique protects the system from overloading with substances, which extended the life time of the sensors and the cycle times are shortened. By this gas-flow control to stabilize the pattern under varying concentrations and analytical conditions is possible.

Individual gases or gas mixtures are classified by their pattern and after a workout recognized. In this case, the unit provides a quick and simple quantitative answer as good or bad, yes or no ... .

Even qualitative answers can be given by training and comparison with the database. With its variety of pattern recognition algorithms allows the system to a broad range of applications - both in the laboratory, and industrial - are applied.

Process Control:

  • dosage of spices in food production
  • supervision of industrial cleaning processes,
  • fermentation processes
  • dosage of artificial odour in natural gas
  • production of polymer packaging material for food industry
  • frying or roast process control

Quality Control
Rancidity of oils, freshness of food, off odour in packaging materials, residual solvents in polymers, degradation of flavours, off odour in medicine, characterization of resins or aroma in beverages

Environmental & Safety Control
Odour in waste water purification plants or in compost plants (correlation with olfactometry), supervision of filters, solvents at workplace atmosphere, smouldering fires, identification of bacteria, leakage control or combustion emissions
