About ION Science
ION Science Ltd is a manufacturer of technologically advanced gas detection equipment and OEM PID gas sensors. The portfolio includes portable, personal, fixed and semi-portable gas and leak detection instruments as well as MiniPID-2 series PID sensors, particulate matter (PM) sensors, VOC monitors such as Falco and Titan, development kits and the SF6 leak detector LeakCheck P1 XTL. The instruments and sensors detect over 950 gases, including benzene, toluene, xylene and sulphur hexafluoride, and deliver reliable readings even in harsh environments; the patented Fence Electrode Technology eliminates the influence of humidity on VOC measurements. Customers are OEMs of portable, personal and fixed gas detection instruments as well as users from oil and petrochemicals, environmental monitoring and occupational safety; Blackline Safety integrates MiniPID 2 into its G7 diffusion cartridges, and the VOC detection technology is used in Formula 1 from the pit lane to fuel testing. The company is headquartered in Fowlmere near Royston in the United Kingdom.
