Smiths Detection LCD 4 & XID
Description
Compact, wearable chemical threat detector
The Smiths Detection LCD 4 is a rugged, body-worn chemical detector that continuously monitors for chemical warfare agents (CWAs) and toxic industrial chemicals (TICs) in the gas and vapour phase. Using non-radioactive Ion Mobility Spectrometry (IMS) technology, it provides advanced warning of threats at or below IDLH levels, helping protect operators in high-risk environments.
LCD 4 automatically identifies the agent type or class and provides information on concentration and dosage, allowing users to quickly understand the severity of exposure. Flexible mounting options let it be worn on a belt, harness or shoulder strap, or used handheld, so responders can maintain full mobility while staying protected.
With long battery life from standard AA cells, simple one-button operation and no routine calibration, the LCD 4 keeps the logistics burden low. Integrated mission data logging, RS232 connectivity and optional extensions such as wireless communication and the XID trace-detection adapter expand its role from personal detector to a networked, multi-threat detection platform.
