Our CALGAZ family, owned by Air Liquide, was founded in Cambridge, Maryland in 1976. To this day, the facility is still in operation and is one of our three global manufacturing powerhouses.
The team truly pioneered the development of the calibration gas market and helped shape many of the products in use today. In years gone by, device calibrations were often cumbersome operations with technicians needing multiple cylinders to check each gas individually.
In 1991, CALGAZ became the first manufacturer to produce the 4 in 1 gas mixture now adopted by manufacturers worldwide and often referred to as “Quad” mixes. This innovation in blending technology enabled users to replace multiple cylinders with one pre-made mixture reducing handling time, cost, and complexity.
The Quad mixes went on to be a best selling product line in the calibration industry and continue to be supplied worldwide to this day into a variety of industries. Our driving force for innovation has always been and always will be making safety accessible to all.
CALGAZ went global in 2014 when Air Liquide purchased a regional calibration gas supplier in the UK and fully integrated them into the CALGAZ business.
Located in Stoke on Trent, the acquisition enabled CALGAZ to bring its market leading products and processes to the European market. Soon after, the existing facility was replaced by a brand new manufacturing location.
Still based in Stoke on Trent, this facility increased production capacity, improved safety and deployed cutting edge manufacturing technology to the European arm of the business.
Still operating today, the Stoke team now proudly supplies Europe, Middle East, African and APAC markets.
As the calibration market continued to grow significantly the Airgas division of Air Liquide acquired Tech Air in 2019 along with their calibration manufacturing business, Gasco.
Gasco became our third manufacturing location, now operating under the CALGAZ brand. The location in Oldsmar Florida started out as a family owned business who built a loyal US customer base underpinned by exceptional customer experience.
Oldsmar is a busy high volume production facility serving many of our end user and distributor markets in the US, perfectly complimenting the production capabilities of Cambridge.
Alongside our acquisitions, CALGAZ also implemented strategic distribution hubs and commercial teams around the world as demand for our products extended beyond the shores of the US and Europe.
We now proudly support distribution locations in Pearland, Rotterdam, Dubai, Singapore and Shanghai, with international sales and customer service teams in Dubai, Singapore and Shanghai.
Over the years our CALGAZ family has seen many changes to customer needs and we are constantly evolving and challenging ourselves to lead the industry.
This is perfectly demonstrated by our early adoption of ISO 9001, 17025 and 17034 standards.
As we celebrate our 50th anniversary in 2026, we have harmonised all legacy products into the CALGAZ brand.
Looking ahead to the future from our corporate HQ in Houston Texas, we have many exciting plans already in motion to further innovate, deliver great customer experience and secure our position as the world’s most established calibration gas supplier.
Here’s to another 50 years of Confidence in Calibration!
