FAQs
Natural Gas Leaks & Safety
What is a natural gas leak?
A natural gas leak occurs when gas escapes from a pipeline, meter, appliance, or connection before it’s intended to be used. Leaks can happen underground or above ground and may be caused by corrosion, damage, installation issues, or aging infrastructure.
Why is early gas leak detection important?
Early detection helps reduce safety risks, minimize service disruptions, and support regulatory compliance. For utilities and first responders, identifying leaks quickly allows teams to prioritize response and manage risk more effectively.
Can you smell a natural gas leak?
Natural gas is odorless, but an odorant is added so many leaks can be detected by smell. However, not all leaks are easily noticeable; especially small, underground, or outdoor leaks so gas detection instruments play a critical role.
FAQs
Gas Detection Instruments
How do gas leak detectors work?
Gas leak detectors use a range of sensor technologies to identify the presence of gas in the air and help locate the source of a leak. Different instruments are designed for different tasks, such as leak investigation (not all reported leaks will be from a natural gas source), surveying, pinpointing or quantifying depending on the environment and application.
What types of gas can SENSIT instruments detect?
SENSIT designs handheld instruments for applications involving natural gas and other combustible gases commonly encountered by utilities and fire services. Natural gas leak survey devices are typically focused on methane and ethane detection. Our Environmental Emissions Monitors are configurable to detect the target hazardous and criteria air pollutants based on the application.
As specific detection capabilities vary by instrument , users should view product pages for more information.
How accurate are portable gas leak detectors?
Accuracy depends on the instrument design, sensor technology, calibration, and how the instrument is maintained. SENSIT instruments are built for repeatable performance in real‑world field conditions and are supported by in-house testing, third party approvals and documented quality systems.
FAQs
SENSIT Products
What makes SENSIT instruments different?
At SENSIT, we focus on:
- Instruments designed for real‑world field use that are adapted to industry work practices
- Clear, usable readings; not unnecessary complexity
- Ongoing support throughout a product’s lifecycle
How long do SENSIT instruments last?
Many SENSIT instruments are used for years (or even decades) in the field when properly maintained. Long‑term serviceability and support are part of the product design philosophy, helping organizations protect their investment in capital equipment.
FAQs
Buying, Service, Support
How do I choose the right product?
The right instrument depends on:
- Your Role/Application
- The Target Gases
- Regulatory and Operational Requirements e.g. approval to use in hazardous areas
- Each SENSIT product is often configurable to enable/disable certain features so we support the selection process through product guidance, documentation, rather than one‑size‑fits‑all recommendations.
Does SENSIT provide service and support after purchase?
Yes. SENSIT supports customers with calibration, service, and technical assistance throughout the life of the instrument; we know our customer run on reliability so we’re there to support.
Is SENSIT a stable, long-term supplier?
SENSIT has over 45 years of experience in gas detection and operates under ISO‑certified quality systems. The company is also part of Halma plc, providing additional long‑term stability and governance.
FAQs
Fire & Emergency Response
What role do gas detection instruments play in fire & emergency response?
Gas detection instruments help fire service teams assess risk, confirm conditions, and support decision‑making during responses involving suspected gas leaks or unknown atmospheres. They provide objective information that complements situational awareness when time and clarity matter most.
What makes a SENSIT product different from a 'four gas meter' typically used by a firefighter?
‘Four gas meters’ are often personal protection devices that detect combustible gas at levels nearing risk of explosion. These types of devices alarm to tell you to retreat away from a hazard. SENSIT gas detectors on the other hand detect much smaller concentrations of combustible gas to aid a user approaching a leak source / potential hazard in order to locate it, document it and make it safe.
Are SENSIT instruments designed specifically for fire departments?
Yes. SENSIT instruments are designed with fire service environments in mind, including unpredictable conditions, varied experience levels, and the need for clear, usable information under pressure. Product design emphasizes reliability, simplicity, and readiness rather than unnecessary complexity.
FAQs
Environmental Emissions Monitoring
How do SENSIT products fit into emissions monitoring programs?
Our fixed point emission monitors are designed to support continuous or semi‑continuous monitoring at specific sites or assets. Rather than replacing handheld instruments or leak detection and repair (LDAR), they complement broader programs by providing ongoing visibility where periodic checks may not be sufficient.
Are SENSIT's Emission Monitors safety devices or environmental reporting tools?
Our products such as the SPOD and RAMP are environmental monitoring instruments intended to support awareness and response. The emissions data they collect may inform environmental or compliance activities, we position these products first as tools to help organizations identify issues early and act appropriately, not as standalone safety devices.
Where are SENSIT's Emission Monitors typically used?
Organizations use our products locations where continuous visibility to emissions data adds value, such as sites with higher consequence, limited access, or historical issues. These can be within the Oil & Gas value chain, within communities, next to industry or even ports and wastewater facilities. Multiple devices are often installed around a site/asset on a fenceline perimeter. However, their mounting is very flexible by design. Hazardous area approved variants can even be mounted within processing facilities (e.g. Oil & Gas refineries) close to potential emissions sources.
