About SENSIT

SENSIT began in 1980 with a husband-and-wife team. Over the past 45 years we’ve grown from humble beginnings to a leading supplier of gas leak detectors to the North American natural gas industry.  

Before entering a building where there is the potential for a lethal gas leak, gas utility personnel will pick up their SENSIT device and put their faith and life in the hands of our efforts. Our instruments may be the only way they will know that an area is potentially explosive or poisonous. 

We also deploy environmental emissions monitors to detect and locate emissions of hazardous gases from industry to our air.  Members of our communities are regularly breathing dangerous levels of volatile organic chemicals, like benzene which is linked to leukemia and other blood cancers. 

SENSIT has been built on providing trust to those who rely on our products to protect their life, property and our environment from hazardous gases.

Today

We continue to combine a robust product offering with our culture of always putting the customer first. Our products increasingly are used not just for individual safety but to protect all of us on earth. Societal and regulatory focus on methane emissions from natural gas is increasing so we’re actively helping our customers find gas leaks to help drive fugitive emissions to zero.  

Our Culture 

We love manufacturing but using our business to make the world safer and cleaner gives our work meaning.  

Leaders at individual operating companies with Halma are given the opportunity to take ownership, be entrepreneurial and operate like they are running their own business. Long story short, we get to make our own decisions on what we think is best for our customers. 

Our employee values are to be R.I.C.H 

Respectful

Respect is the default, it isn’t earned. We give every member of the team it. If others feel respected by a person, they’ll return it and work effectively together.

Inclusive 

We seek out and consider different perspectives to inform decision-making and learn from others. We adjust to our environment to keep up with priorities, projects, clients and technology.  

Charitable 

At SENSIT, we’re proud to support causes that matter to our team and community. We give back to organizations that inspire change and reflect the values we live every day.

Honesty 

Our strengths only diminish if we don’t take the opportunity to reflect and learn. We want to know what we can do better to be a trusted partner to our customers.
