Aeroqual VOC PID Sensor Head 0-2000 ppm (PDH - VOCH)

This Volatile Organic Compound (VOC) sensor head uses Photo Ionization Detector (PID) technology and will measure VOC's from 0-2000 ppm at 0.1 ppm resolution while providing 0.2 ppm +/- 10% accuracy.

VOC Information


This Volatile Organic Compound (VOC) sensor head uses Photo Ionization Detector (PID) technology and will measure VOC's from 0-2000 ppm at 0.1 ppm resolution while providing 0.2 ppm +/- 10% accuracy.

This sensor head will be a direct fit onto any Series-200, Series-300, or Series-500 Aeroqual ozone monitor.  This head can be purchased as an addition to your existing monitor, or with a new base unit.  To purchase with a base unit see our Aeroqual ozone monitor page.  If you currently have an Aeroqual ozone monitor this sensor will be a direct fit for your current monitor.  The Series-200, Series-300, or Series-500 will automatically detect this as a 0-1000 ppm VOC head and react accordingly. 

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

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.

Sensor Type

There are two types of Aeroqual sensors, type 1 and type 2. 
The type 1 is used with the S-200, S-300, S-500, and S-900 monitors. 
The type 2 is calibrated specifically with fittings on the end allowing it to be used with the ENC enclosure and in the S930
