The PEN3 (Portable Electronic Nose) is a portable odour measurement instrument equipped with Metal Oxide Semiconductor (MOS) sensors. It is capable of recognising individual gases or complex mixtures by undergoing a training phase to “memorise” their specific sensory characteristics.

The device provides both qualitative and quantitative results through advanced chemometric data analysis, allowing for precise comparison against a specific database of sensory fingerprints.

The possible applications of the instrument are countless, both in the laboratory and in industrial contexts:

• spicing dosage in food production.
• Industrial process supervision.
• Fermentation processes.
• Artificial odorant dosage in natural gas.
• Production of polymeric packaging material for the food industry.
• Control of the frying or roasting process.
• Quality control (oil rancidity, food freshness, off-odours in packaging materials, residual solvents in polymers, flavour degradation, off-odours in pharmaceuticals, resin characterisation, beverage aroma).
• Environmental control and safety (odour in wastewater treatment plants or composting plants, solvents in the workplace, fires, identification of bacteria, emission control).
