This Volatile Organic Compound (VOC) sensor head using Gas Sensitive Semiconductor (GSS) technology will measure VOC's from 0-500 ppm with a 1 ppm resolution and 10% accuracy.

This sensor uses active sensor technology with an internal fan to pull air across the GSS sensor at a specific flow rate for accurate gas detection.  This fan will pull a fresh gas stream across the GSS sensor every 30 seconds for accurate VOC detection.. 

Calibrated against isobutylene (other specific VOC calibrations are available on request).

WHY USE A VOC SENSOR?

Volatile organic compounds (VOCs) are organic chemicals that are present in the gas phase at ordinary room temperature. The term VOC covers a wide range of chemical compounds that are both man-made or naturally occurring. Some VOCs are harmful to human health or can cause environmental damage. Although volatile organic compounds are usually not acutely toxic, they often cause long-term health effects from continuous low level exposure.

Indoor VOC

The concentration of volatile organic compounds found in indoor environments is significantly higher when compared to outdoor levels. VOCs are emitted from a wide range of products commonly found inside buildings. They include paint, cleaning supplies, furnishings, glues, permanent markers and printing equipment. Levels can be particularly high when there is limited ventilation. Exposure to high concentrations of VOCs can lead to throat irritation, headaches and damage to internal organs. The severity of the health effect depends largely on the type of organic compound present as well as the exposure time. Aeroqual offers a wide range of portable and fixed monitors with a VOC sensor for indoor VOC monitoring.

Outdoor VOC

A large proportion of outdoor VOC is biologically generated by plants and released via the leaves. The concentration emitted depends on the type of plant as well as environmental factors including temperature and sunlight. Urban planners will take this into consideration when deciding on the types of vegetation to plant in towns and cities. Although natural emissions tend to be larger overall, anthropogenic sources are more of a concern in urban areas. Emissions from the oil and gas industry, solvent usage and transportation all contribute to increased VOC concentrations. Aeroqual can provide both portable and fixed monitors with a VOC sensor to measure outdoor VOC concentrations.

Aeroqual VOC Sensors Selectivity

The PID and GSS VOC sensors available at Aeroqual are non-selective sensors. They have been calibrated against isobutelyne but will respond to a wide range of VOCs at varying degrees of sensitivity. Correction factors can be provided for a specific VOC response if requested. If a specific VOC is being measured, no other VOCs should be present in the monitoring environment to avoid a cross interference.

Calibration:

This Volatile Organic Compound (VOC) sensor head using Gas Sensitive Semiconductor (GSS) technology will measure VOC's from 0-500 ppm with a 1 ppm resolution and 10% accuracy. The Aeroqual AQ VP sensor has a detection range of 0-500 ppm, so the calibration gas you use must fall within this range. Refer to the table below for our recommended calibration gas options.
