Odor sensors are an essential element to replace a person's nose.

By using sensors that can detect major odor substances, we can monitor 24 hours in the area where odor is frequently generated. Nowadays, much attention has been paid to the environment and safety. Odor sensors are recognized as essential elements in industrial complexes and residential areas.

Customized Sensor
Since every business site has different odor causing substances, odor sensor equipment should be constructed selectively. It analyzes mainly the odor substances generated at the sensor installation site and installs the sensor that matches the detected substance among the 24 sensors that can detect odor substances. With these optional sensors, more accurate results can be obtained.
