S-VOC (Limited stock)

VOC SENSOR WITH DIGITAL AND ANALOG OUTPUTS

An intelligent device for accurate assessment of indoor air quality

Indoor environments contain various gases and microscopic particles that can impact human health. The S-VOC is designed to accurately and reliably determine the level of volatile organic compounds (VOC), typically associated with cigarette smoke, cooking smells, and other pollutants:

  • CO, CH4, LPG
  • Ketones
  • Organic acids
  • Amines
  • Aliphatic hydrocarbons
  • Aromatic hydrocarbons

The S-VOC also evaluates the concentration of carbon dioxide, an essential criterion in Indoor Air Quality measurement (see graph below). In any environment requiring demand controlled ventilation, such as commercial facilities, offices, classrooms, and private homes (kitchen, bathroom, etc.), the S-VOC now makes it possible to assess more than just the CO2 criterion of IAQ, and to come closer to perceived air quality. Thanks to its compact design, the S-VOC is simple to fit into your installation and your room.

A pertinent and extended measurement of indoor air quality

Using MOS* technology, the S-VOC measures the concentration of VOC and odours in real time and evaluates the CO2 level of the room. Its output signal reports values from 0 to 2 000 on a ”CO2 equivalent ppm” IAQ scale. This signal is available simultaneously in two forms: analog (0-10 V) and digital (PWM). *MOS (Metal Oxide Semiconductor) technology: change of the electrical characteristics of the sensing layer depending on the nature and the concentration of the VOC which are detected.

S-PRE/DAY-NIGHT/T (Limited stock) - Sensors

Occupancy sensor with light and temperature sensor for modbus communication

One of the biggest challenges, that we are encountering today is the balance between comfort, security and the efficiency of energy. When it comes to occupants’ comfort in an indoor area, both residential as well as non-residential markets, the building constructors are providing a best in class experience for the occupants with well-equipped building automation solutions.

S-CO2/T (Limited stock) - Sensors

CO2 and temperature sensor for Modbus communication

Nowadays, the buildings are nearly air-tight, entailing a risk of poor indoor air quality if there is a lack of ventilation. Indoor air quality can generally be assessed by measuring the concentration of carbon dioxide, known to be representative of indoor air conditions. Aereco introduces the new S-CO2/T Modbus, an effective CO2 sensor specially designed to accurately assess indoor CO2 concentrations, in order to help systems optimize indoor air quality.
