With today’s acquisition of IST, we are reaffirming our commitment to being a leader in the gas detection space.”

IST holds a technology leadership position in the gas and flame detection industry and is strongly committed to innovating in industrial safety solutions. From groundbreaking wireless gas-detection technology to the first SIL3 certified triple IR flame detector, IST provides among the most advanced and reliable solutions, protecting lives and workplaces around the world. IST brings strong market presence in Europe, the Middle East, and the Gulf Coast U.S. region and will complement the Scott Safety Flame and Gas Detection business.

“I am extremely proud to be part of the gas detection industry where our focus is to provide products to enable people to work safely in environments that may not always be safe,” said Vigdor. “The high quality, technically advanced products manufactured by Detcon, Simtronics, Oldham, Gas Measurement Instruments, and DSA along with their knowledge of the industry will help us continue to provide the best products to our customers so we can protect what matters most.”

In addition, IST has an extensive network of experienced and talented employees who will help to shape the future of the global flame and gas detection industry,” said Sean Magee, General Manager, Flame and Gas Detection, Scott Safety. “We look forward to working with the IST family to develop our collective strategy for driving growth.”
