Why MDU

Built for the front line

🧪

Broad Chemical Coverage

Electrochemical, PID, PM, LEL, and radiation sensors in a single modular unit — configured to your mission requirements.

⚡

Sub-60s Cloud Latency

Data reaches your command team in under 60 seconds. Real-time situational awareness on web and mobile dashboards.

🔩

Rugged Stainless Build

Stainless steel enclosure with corner LED status indicators. Designed for the environments first responders actually work in.

📡

Online & Offline Variants

LTE-connected for full cloud access, or 915MHz local for classified and infrastructure-free deployments.

☁️

Cloud Control

Configure, monitor, and command devices remotely. Full web analytics and mobile quick-glance interface included.

🔧

Modular Sensor Stack

Daisy-chained sensor boards cover gases, particulates, LEL, PID, and radiation. Swap in what each deployment needs.
