Based on leading Ion Mobility Spectrometry (IMS) technology, the LCD 4 is an advanced warning device, that alarms to gas and vapour threats detected and identified at or below immediately dangerous to life and health (IDLH) levels, by determining the agent or type, class, concentration and dosage of chemical exposure. It can also be used as a screening and survey device.

Flexible mounting options allow the LCD 4 to be handheld or clipped to a belt, harness or shoulder strap, to enable the user to undertake their primary role without obstruction. Features include both audible and visual alarms plus a clear, easy-to-read liquid crystal display.

This device is very simple to operate and requires no calibration or complicated routine maintenance. The impressive performance of the LCD 4 combined with its ergonomic design and functionality provides a wide range of user capability while ensuring a minimal logistic burden.

LCD 4 can record up to 72 hours of mission data for future analysis and features RS232 connectivity for data downloads and post-mission analysis. The device is designed to meet the requirements of MIL-STD-810 and MIL-STD-461.

New product extensions and accessories extend the capabilities of the LCD 4, including wireless connectivity and detection of trace explosive, narcotics including fentanyls, and novichok chemical agents.
