What is a VOC Sensor and why would I need one?

New product: VPro
We are happy to announce that the VPro portable VOC sensor is now available at Senko Europe. The VOC sensors provide a unique sensor technology and detection capability that differs largely from your standard gas detection units. Although different, they are essential to some industries to keep workers safe and identify areas of hazard.
What is a VOC sensor?
A VOC sensor can come in the form of a fixed or portable gas detection unit, utilising a unique lamp-based technology called a PID (Photoionization detector) to provide measurements of Volatile organic compounds, or VOCs. There are thousands of chemicals and gases that come under the categorisation of a VOCs, and PID technology is one of the most effective ways to detect these gases.
PIDs have 3 different lamp types available; 9.8eV, 10.6 eV and 11.7 eV. The names of these different sensor types indicate the level of electronic volts administered by each lamp. The reason that you may require a different eV level for a PID sensor is because it may be more effective at accurately detecting the type of gas that you are targeting.
Why would I need a VOC sensor like the VPro?
As mentioned previously, PID technology is one of the most effective ways of measuring VOCs. Although some VOCs overlap with flammable gases, therefore can be detected by a flammable gas detector, PIDs are the only technology that can detect such a wide range of VOCs at low levels. Depending on the VOC gas that you are targeting, the PID is the most effective form of gas detection technology for these gas types.
Although present in everyday items such as new furniture, petrol and new cars, VOCs largely aren’t hazardous in these scenarios due to the extremely low levels of gas emitted. However, in industry, VOCs can accumulate quickly. In workplaces such as paint manufacturing, Oil and gas and waste management, workers are dealing with massive amounts of solvents and materials that contain VOCs in their non-gaseous forms. However, at room temperature in a room temperature atmosphere, these VOCs evaporate to become VOC gases. And due to the sheer volume of VOCs evaporating, the environment can quickly become hazardous to health.
VOCs are toxic gases but are different to your more typical toxic gases such as Hydrogen Sulphide. Inhaling most VOCs will not cause immediate damage and health problems immediately, however VOCs can cause long term damage such as organ damage and cancers. Because of this and the daily contact workers may have with VOC containing materials, it is important to mitigate the risk wherever possible. This is where a VOC monitor will come into play.

The VPro VOC sensor
The VPro is designed for tasks such as spot checking and personal detection of a wide range of gases classed as VOCs. The VPro comes with a built-in gas library of response factors to easily recognise one of the hundreds of VOCs you may be targeting. The VPro comes with a full kit of accessories to help support your day-to-day activities across a huge range of sites and applications, reducing the overall cost of ownership.
Employing a VOC detector you can trust is important in your day to day work, which is why Senko have extended their range of high-quality products to offer this type of support to a wider range of industries.
