Want to calibrate instruments yourself instead of sending them away?

Save time and money by doing your own calibrations!

All you need is some calibration gas and a regulator to get the job done. We stock a huge range of calibration gases in different sizes to help you keep your units on site.
Got a specific gas requirement? Just ask us!

Already using calibration gas and want to save more money?

Consider using larger cylinders through our calibration gas consumption calculator - a handy tool we created just for you!

Don't forget! GasTech offer a free recycling service for all calibration gas cylinders... you can either send them into us or if they're Portagas, put them in the post! Take a closer look at the 'Strip and Ship" video for Portagas cylinders below...
