What is VOC Meter?
This is a device that is commonly used to test soil, water, and air for contaminants; it is also known as VOC analyzer. VOC meters are commonly used in industries to measure pollutants in air and water around the factories, in clean water, sewage monitoring, and in agriculture. They use photoionization detector PID or gas chromatography to analyze samples.
PID usually employs the use of UV light to mainly excite the volatile organic compounds, the presence of the contaminants appear as ion current thus alerting the user of the presence of specific contaminants. Gas chromatography, on the other hand, uses the gas formed by the contaminant to form a spectrum that alerts on the type of particles present in the sample.
What is VOC Meter key features?
A VOC meter is up to 200 times more sensitive to volatile organic compounds than the typical Heated Metal Oxide Sensors (HMOS). The gadget has the capability of testing 252 chemicals, thus surpasses any other VOC testing method to date. Also, the device is capable of collecting air samples for laboratory testing of presence of Volatile organic compounds.
A VOC meter is capable of storing data for up to six months. Also, it provides 1-minute intervals for download to a PC.
Tested and Proven
The VOC meter has been tested and proven using PID technology. It has patented 3D sensors that are capable of giving up to 3 seconds of response time ranging from 0.1 ppm to 10.000 ppm; it is also resistant to dirt and moisture.
VOC is user-friendly
This device has a user-friendly screen that makes it easier to perform basic applications as well as the advanced options. In addition to these features, the screen provides easy for reading display with a backlight.
A VOC meter features a self-cleaning sensor and lamp. With this feature, highly helps regarding maintenance and calibration of the device.
About VOC monitoring
Since 1998, it has been perceived that In Vitro Fertilization (IVF), are at a very high risk of contamination from the harmful Volatile Organic Compounds (VOC’s). Due to this factor, RI VOC has been commissioned to serve for detection of the VOC found at very low levels. The volatile organic compounds are found almost everywhere, for instance through field tests, they have been found to exist in; lab cabinets, incubators, incubator gas tubing, surprising in Laboratories where VOC filtration had been earlier used.
How is VOC meter used?
The use of this device is pretty simple, you just start the device and use it to identify areas that have Volatile Organic Compounds. In areas where the VOC’s are high than the recommended level, an audible alarm will sound, and the concentration of the VOC present in the particular area will be displayed on the screen.
For additional protection and safety, a VOC meter can be mounted on walls, and the VOC’s levels monitored continuously.
How does it work?
Photo-Ionization Detection (PID) the technology that performs the analysis to establish the presence of volatile organic compounds in a given environment.
In this case, air is taken in into the detection chamber by a pump. Subsequently, ultraviolet light is then used to break the molecular bonds or in other words, ionize any organic chemicals present in the air taken in.
The ions obtained through ionization are then charged electrically, the VOC meter then is capable of detecting them as a tiny electrical conductivity. This, in other words, means that the more the contamination, the higher the current that flows.
The international agreement presumes that the Guidelines for Indoor Air Quality (IAQ) range from 0.10 to approximately 0.65 ppm but dependence on the location.
Again, the standard threshold for toxicity of Acrolein in the mouse embryo is approximately 0.58ppm when dissolved in media.
Consideration for purchase of a VOC Meter
Now that you have understood what VOC meter is it is also good to check the considerations that you should make before buying one. It is good to know that some VOC meter are used to test only for air while other VOC meters test for water and soil. Establish also the number of contaminants that can be tested per single test.
