VOC Detectors Used as Part of Chinese Metro Security

Further demonstrating the flexibility of its advanced gas monitoring instrumentation, Ion Science (UK) has recently supplied 30 Tiger Photoionisation Detectors (PIDs) to Harbin Metro Group Ltd. Purchased via distributor, ChuWah, the well proven Volatile Organic Compound (VOC) monitors are being used as part of a security and anti-terrorism screening process to check passengers’ luggage and bags.

Harbin Metro is the metro system of Harbin, the provincial capital of Heilongjiang Province in north eastern China.

Lu Yu, Ion Science Territory Manager for Greater China comments: “The need to introduce new security measures led Harbin Metro Group to choose a significant amount of Ion Science Tiger VOC detectors. These are being used for monitoring passengers, luggage and bags during security screening.

Lu adds: “Security personnel are doing quick checks at the entrance of the Harbin metro stations before passengers proceed into the subway to board their trains. This customer has not used PIDs before but our distributor, ChuWah, did a great job of highlighting the Tiger’s suitability for the application. As a result, Harbin Metro Group chose the Ion Science instrument due to its robust design, portability and long life rechargeable Li-ion battery for 24-hours usage and fast charging.”

“This latest order underlines the expanding market in China for high quality gas detection instrumentation. As a result, we continue to look for strategic partners with relevant specialist industry experience,” he concludes.

Independently verified as being the industry’s best performing PID, the Tiger provided the most stable, repeatable readings, when tested against competing instruments in humid and contaminated conditions.

The instrument incorporates Ion Science’s well proven MiniPID. This simple plug and play sensor has been specially developed to deliver a dynamic and reliable response to thousands of VOCs.

Designed for rapid, accurate detection, with an unrivalled response time of just two seconds, and the widest measurement range of one part per billion (ppb) to 20,000 parts per million (ppm)*, the robust Tiger is ready to use, straight out of the box, and extremely simple to set up.

It offers worldwide Intrinsic Safety (IS) certification, making it suitable for use in potentially explosive, hazardous environments, and also meets ATEX, IECEx, and North American standards.

Inexpensive disposable parts such as filters and lamps are easy to change, minimising downtime. Simple connectivity to a PC via the USB allows data to be downloaded quickly.
