Scentinal SL50 – Air and Odour Monitoring Station
The Scentinal SL50 Air and Odour Monitoring Station utilises sensing modules (up to 20) from Non-Dispersive Infrared Detector, Photo-Ionization Detector, Electro-Chemical Cell, Laser Scattered Counter and Metal Oxide Sensors. Data can be transmitted to a central server and is also kept locally on the device. The impressive Sensor Information Management System doesn’t just store and visualise results, it also allows for calibrations, remote configs and the diagnosis of multiple Scentinal units.
Designed to be highly accurate due to ppd level sensors, the Scentinal SL50 will simultaneously monitor ambient pollutants and odour emissions. It can conduct continuous monitoring of odorous gases including Ammonia, VOCs, H2S and SO2 as well as non-odorous gases Methane and CO2.
Scentinal is more than just a monitoring station, it can also act as an intelligent process controller.
Air and Odour Monitoring Flexibility
There are 20 sensors available for selection from the available sensor list. They have been divided up into 5 easy to navigate categories which include:
- Photo-Ionization Detector,
- Metal Oxide Sensor.
- Electro-Chemical Sensor,
- Non-Dispersive Infrared Sensor,
- Laser Scattered Counter (for PM1-10), and
The Scentinal SL50 features a modular design and can be customised with the sensors you require for your specific needs.
Scentinal is the world’s only air quality monitoring station that provides simultaneous pollutant and odour
measurements. Data from individual sensors is processed by Scentroid’s chemical and olfactometric
correlation system to determine odour concentration in OU/m3. The system uses a neural network learning
algorithm to determine odour concentration from chemical readings.
Olfactometric measurements, using the Scentroid SM100 Field Olfactometer, are collected periodically
(monthly, bi-monthly, or semi-annually) and are inputted into the learning algorithm along with recorded
chemical composition. This sophisticated algorithm will then create a non-linear relationship between
chemical readings and odour concentration. This data is used to teach the network and enhance the accuracy
of odour concentration prediction from chemical composition. The advantage of this system over other
competing technologies such as E-Noses is that chemical to odour concentration is based on routinely
gathered olfactometric data and therefore is always up to date regardless of changes to the plant processes.
