What is the purpose of the First Defender RMX?

Identify unknown solid & liquid chemicals in the field Measure ambient temperature Detect heavy metals Map terrain

Correct Answer:

Identify unknown solid & liquid chemicals in the field

Explanation:

The First Defender RMX is designed to identify unknown solid and liquid chemicals right in the field. It’s a handheld Raman spectroscopy tool that shines a laser on a sample and analyzes the light scattered back. By comparing the resulting spectrum to a built-in library, it provides candidate identifications with confidence levels and hazard information. This capability lets responders quickly determine what a substance is and decide on appropriate PPE and response actions, which is exactly what the device is built to do. This isn’t a temperature meter, a device for detecting heavy metals, or a tool for mapping terrain. Those functions belong to other instruments or methods, whereas the RMX’s purpose centers on rapid chemical identification at the scene.
