LEL-MPS Combustible Gas Sensor

When your workers' lives are at stake, accuracy matters.


Say hello to accurate readings across multiple gases, automatic gas classification and direct-to-cloud data streaming.

Blackline Safety and NevadaNano have partnered to add the Molecular Property Spectrometer (MPS™) Flammable Gas Sensor to the G7 line of connected safety monitors. With TrueLEL™, MPS is the most accurate combustible gas sensor on the market, delivering high accuracy for a dozen combustible gases — including hydrogen — while eliminating issues with traditional sensors.

Key features:

  • Accurate readings without correction factors
  • 5+ year lifetime
  • Poison immune
  • Fail-safe and self-diagnostic
  • No more false alarms

Your Employees Have Never Been This Safe

With the MPS sensor, your employees will have the most accurate and comprehensive view of the safety of their surroundings. The MPS sensor provides the most accurate reading for twelve combustible gases simultaneously, without the need for any correction factors.

Immune to poisoning (including silicones), the MPS sensor refuses to be compromised. And, if for any reason the sensor isn’t functioning properly, it’s built-in fail-safe design will alert the user. Your workers will never unknowingly be vulnerable in a hazardous environment again.

Less Down Time - More Go Time

The MPS sensor has built-in environmental compensation and doesn’t need a correction factor, meaning your employees will never be interrupted by unnecessary false alarms again. Its long lifespan also ensures your workers can confidently use this sensor for years at a time, cutting through any learning curves.

Accurately and Linearly Detects a Dozen Gases


Most Accurate LEL Sensor

Unlike traditional sensors that are accurate to one gas, G7 wearables linearly and accurately detect the TrueLEL TM — the true lower explosive limit of individual gases and mixtures when equipped with the MPS sensor. This guarantees accuracy across the most common gases including:

Automated Gas Classification

In addition to the MPS sensor accurately detecting multiple gases at once, it automatically classifies them into one of six gas categories. All data streams directly to the cloud for industry-leading data analytics, providing visibility into your worksite like never before. In contrast, conventional LEL sensors can accurately detect only a single gas that they were calibrated for, delivering inaccurate readings when exposed to other gases.


Defying Convention

With the MPS sensor, your employees will have the most accurate and comprehensive view of the safety of their surroundings.

How is a combustible gas detector different from other gas detectors?
Some gases that workers are exposed to are flammable at certain concentrations. A combustible gas detector monitors the area for concentrations of such flammable gases, reporting on their concentrations before they become dangerous or combustible.
Which gases does the MPS sensor monitor for?

Use the FAQ section of your site to answer those routine questions that always come up and need to be answered. This is a great way to tell us more about what you can offer, fill in some details that might intrigue us, and show us how knowledgeable and helpful you can be.

The MPS sensor is highly accurate for the most common flammable gases including:


•  Butane
•  Pentane
•  Hexane
•  Xylene

•  Ethylene
•  Propylene
•  Isopropanol
•  And More

What does LEL mean in gas detection?
There is a limited range of gas and air concentrations within which combustion is possible and this range is unique to each gas or vapor. LEL refers to the lower explosive limit of a particular gas or vapor, signaling that a particular gas is reaching a concentration in which combustion is possible.
What is considered a safe LEL level?
Once a gas reaches 100% of its LEL level, it is potentially combustible, and therefore unsafe. This means that a flammable gas detector needs to be sensitive and accurate enough to detect these combustible gases from 0 – 100% LEL as shutdown and clearance of the site must be initiated before 100% of LEL is reached.
Why are confined spaces considered hazardous?
A confined space is an enclosed or partially enclosed area that, while it may be big enough for a worker to enter, are not designed for a person to work in regularly as they often lack proper ventilation systems, lighting or other resources. Confined spaces are prone to atmospheric hazards such as a toxic gas leak or lack of oxygen, making these areas more hazardous than another workspace.
How does an LEL monitor lessen the risks in confined spaces?
By monitoring the levels of combustible gases in confined spaces, the MPS sensor protects workers in a potentially hazardous environment.
