Benzene Gas Sensors (C6H6)

Benzene Gas Sensor Solutions by International Gas Detectors Ltd.

Benzene is a colourless or light-yellow gas that evaporates quickly in the atmosphere. Its molecular formula is C6H6, being composed of 6 Carbon atoms and 6 Hydrogen atoms, thus making it a Hydrocarbon as well as a VOC. It has a sweet and aromatic scent, making it partially responsible for the scent around petrol stations. Due to its vapours being heavier than air, it can settle into low lying areas very quickly, so a large amount of this gas can build up unnoticed. Therefore, implementing a Benzene gas sensor is essential to prevent this build up and prevent the harm to personnel.

International Gas Detectors can provide a complete Benzene gas sensor solution, perfectly suited to your industry’s needs, including:

Properties of Benzene Gas:

  • Consists of only Carbon and Hydrogen atoms
  • Melting Point: 5.53 °C (41.95 °F; 278.68 K)
  • Boiling Point: 80.1 °C (176.2 °F; 353.2 K)
  • Heavier than air gas
  • Immiscible in water but soluble in organic solvents

Hazards of Benzene Gas

Benzene is a massively carcinogenic gas, increasing the risk of cancer and other related illnesses. For example, research has found benzene to increase the risk of bone marrow failure, acute leukemia and cardiovascular diseases after long term exposure. Short term exposure to high concentrations of benzene is known to cause headaches, tremors, tiredness and nausea, thus even short term exposure can cause dangerous health effects.

In 1948, the American petroleum institute stated that there is no safe exposure limit for benzene, and the only completely safe exposure level is 0. This demonstrates just how dangerous Benzene is to the health of personnel, and with a TWA of just 1ppm, it makes it evermore important to implement a Benzene gas sensor wherever this gas is being used.

Applications requiring a Benzene gas sensor:

Benzene can appear in a wide range of industries due it being produces naturally and through human processes. For example, benzene gas appear in volcanic eruptions as well as through tobacco smoke. Thus, there are a wide range of areas that may need to implement a Benzene gas sensor.

Industrially, Benzene is most commonly found in crude oil and in petroleum fuels. Thus, it appears frequently across the Oil and Gas industry due to it being drilled, processed and refined, releasing this harmful gas. Benzene is also used in the manufacturing industry to help in creating drugs, adhesives, plastics, lubricants, rubbers, dyes, synthetic fibres (etc). Therefore, it can be found across a huge range of unexpected industries, making it even more essential to implement a Benzene gas sensor wherever it can possibly pop up.

Here are a few more industries that require the use of a Benzene gas sensor:

  • Arson Investigations
  • Hazmat response
  • Soil remediation
  • Metal works
  • Chemical Manufacturing


IGD Benzene Gas Sensor Solutions

Backed by our century of experience in PID technology, the team at IGD have developed the new standard for fixed Benzene gas sensors in our latest PID. Although not specific to Benzene, our latest PID is an ideal first responder to Benzene gas. This can be used in conjunction with our Portable Benzene gas sensor to create the perfect benzene solution for your application.

Our new proprietary UV lamp technology utilises a non-electrode lamp design. This curtails the effects of sputtering and contamination, a common issue of current PID technology. Sputtering and contamination can affect the lifetime and accuracy of a PID, thus it is vital to negate this to ensure your Benzene gas sensor is working at the highest quality.

Our latest PID offers a 200% longer lifetime than the market standard with our unique non-electrode design, lasting an outstanding 30,000 hours. This raises the bar for Benzene gas sensor technology, massively reducing the cost of upkeep and replacements whilst ensuring your Benzene gas sensor is performing as it should for longer.

The common issues of humidity and temperature are massively reduced with IGDs revolutionary Benzene gas sensor. This eliminates the possibilities of false readings and drift whilst not affecting their performance; a very important quality to ensure your life safety system is performing at its maximum capability.

These are just a few of the benefits of our latest fixed PID detection range, check out our full PID range here to find out more about our wide range of detectably better benzene gas sensor options.

Portable Benzene Gas Sensor Solutions

The NEO PID Benzene gas sensor from mPower is the perfect companion for easy, portable Benzene detection. Our partnership with mPower guarantees you are receiving detectably better support and servicing from the UKs approved mPower provider.

The NEO Benzene gas sensor measures in a range of 0.05-200ppm, offering the most accurate benzene detection available on the market. This Benzene gas sensor comes with 10 easily replaceable filter tubes at no extra cost, massively increasing convenience should tubes need replacing in the field as well as lowering the initial purchase cost with these free extras. This revolutionary new product from mPower is more durable than any alternatives on the market. Equipped with a full range of approvals to ensure your competence in the product.

Offering a flow rate of 400cc/min compared to the market standard of 220cc/min, the NEO Benzene gas sensor has under half the sample time of the market standard, making it the fastest on the market. This feature is vital in industries such as oil and gas where money is lost every second wasted, making every minute count! Not only does it have a faster sampling rate, but it is also highly efficient. The NEO Benzene gas sensor uses a smart sampling technology, ensuring the tube does not become over saturated. Thus, making the most of each tube whilst guaranteeing your device is working in top condition.

These are just a few of the benefits of the NEO Benzene gas sensor, check out the product page here to find out more.
