Founded in 1959 by Joshua Sieger in Poole, UK, where it still has a base today. The company was named EIC-Sieger and then J&S Sieger Ltd in 1961. Responsible for the first low-power catalytic bead sensor, the Mark 9, immune to cross-sensitivity and designed for use on boats. At the time, few companies offered gas detection solutions and those that did mainly targeted mining.
The company pioneered Chemcassette technology in 1971, which provided proof of gas presence—using colourimetric paper tape that changed in colour when exposed to the target gas. This technique is still used today.
In 1979 Zellweger Luwa Group acquired J&S Sieger Ltd and rebranded it to Zellweger Analytics. Two years later, MDA Scientific was acquired, specialising in gas detection products for semiconductor fabrications and laboratories. The result was a comprehensive range of Chemcassettes and detection solutions for a variety of exotic gases.
During the 1980s, more products were launched; the Siegestor 7 (SG7), a poison resistant catalytic bead sensor, fixed gas transmitters with one-person set up/calibration functionality and remote sensor capability (1050 & 1053 ranges). Gas controllers which combined with detectors, provide a complete gas detection solution.
During 1985 optical gas detection technology was used to develop the 5050, an infrared point flammable gas detector. Working with Shell during 1987, Searchline was created, the first hazardous area certified Open Path detector, which is still available in an updated form today.
Series 2000 transmitters were introduced during the 90s, providing easy sensor replacement in hazardous areas without needing a hot work permit, now superseded by the 3000 range. 1996 saw the acquisition of Neotronics, a portable gas monitor manufacturer, which resulted in the launch of the Impact gas detector in 2001 that used cartridge-based sensors and offered the first automatic calibration device, the Enforcer.
In 2005 Zellweger Analytics was acquired by Honeywell and rebranded Honeywell Analytics and incorporated into their Life Safety division. In 2007 MST technology, a German company, was purchased, offering gas detection specialism in semiconductor and laboratory settings, resulting in the introduction of the Satellite into the Honeywell Analytics portfolio. The Zareba range was also launched, offering low-cost fixed gas instruments for customers.
BW Technologies was bought on March 24, 2006, offering Honeywell a significant foothold into the portable gas detection market with the world-renowned BW brand. UK based First Technology PLC was also acquired, including sensor manufacturer City Technology, who produce the Sensoric range.
In 2012 Fire Sentry, a flame detector manufacturer, was purchased. RAE Systems Inc was bought in June 2013, a manufacturer of portable and fixed gas detection instruments and radiation and photo-ionisation sensing devices.
Deploying the latest technology to offer wired or wireless gas detection, the Honeywell Analytics range includes fixed and portable instruments along with control systems supplied to a multitude of industries across the world. Combining 200 years of experience in the design, manufacture and technology of gas detection.
