Honeywell Analytics Index

A continuously evolving company, Honeywell Analytics has been doing so since its beginnings nearly 50 years ago.

The Honeywell Analytics company was formed in the United Kingdom by Joshua Sieger in 1959. Joshua Sieger was a gas detection pioneer and the inventor of the first reliable catalytic bead. A keen boating enthusiast, Joshua Sieger recognised a requirement for a reliable gas detection service, from time spent in the boating circle.

Joshua Sieger then launched the Siegistor, which set the benchmark for catalytic bead flammable gas detection technology. This brought Joshua Sieger huge success and in 1961, Joshua Sieger's company (known as J&S Sieger Ltd) was commissioned by Shell to devise an entire gas detection system for its white oil storage depot in Gibraltar.

Just before 1980, a division of the Zellweger Luwa group called Zellweger Analytics acquired J&S Sieger Ltd, which marked the company's entry into flammable gas detection. Over the next 17 years, a number of additional brands were acquired and brought into its growing family, including Neotronics Technology, acquired in 1996 and Zareba in 2005.

The huge growth of the Zellweger Analytics company led market leader Honeywell to acquire them in 2005. This was when the company was first known as Honeywell Analytics.

The Honeywell Analytics company today has branches all over the globe and sells its product range internationally to many different types of industry and for many different applications. Thanks to its fantastic understanding of customer requirements along with a constant commitment to the development of new technology, Honeywell Analytics remains a global leader in gas detection and a name that is synonymous with the highest standards of product, service and innovation.
