Fixed Chemical Detector

ChemProX‑DS is a fixed chemical detector that works stand‑alone or as a CBRN system node. It pairs 24/7 CWA/TIC monitoring with a local colour display that can show full system status (connected detectors, alarms, faults and trend lines), giving operators system‑level situational awareness at a glance. With Modbus TCP/IP & RTU, Ethernet/RS‑485, digital/relay I/O and current loops, it integrates cleanly with BMS/IPMS and legacy Bertin Environics networks. No routine calibration is required; a built‑in configuration tool, chemical database, NFPA‑704 hazard diamond and embedded SOPs streamline commissioning and maintenance.

Why teams choose ChemProX‑DS

• System awareness: See detector status, alarms, faults and trend lines (e.g., rising chemical levels) before thresholds trip.
• From node to hub: Connect radiation/biological detectors and share their status through the same UI; export to BMS/IPMS.
• Proven, orthogonal sensing: Open‑loop IMS with additional sensors for sensitivity and false‑alarm rejection.
• Built for service life: IP65 enclosure; tested to MIL‑STD‑810H (shock/vibration) and MIL‑STD‑461G (EMC); marine‑class standards (IACS UR E10 / DNV‑CG‑0339).

• Armoured & light CBRN reconnaissance vehicles
• Critical‑infrastructure monitoring (transport hubs, stadia, corporate campuses)
• Industrial vapour monitoring (ducts, rooms, outdoor enclosures).

Options & accessories

Heated sampling lines (air‑duct/outdoor), external alarm units (light bar), Remote Unit (RU), UPS/external power supplies, and RTU modules for expanded connectivity.

FAQs

Can it act as a “mini C2” for CBRN sensors?

Yes, connect other detectors and see combined status on the ChemProX‑DS display; forward to BMS/IPMS over Modbus.

What maintenance is required?

No routine calibration; use the built‑in configuration tool, database, NFPA‑704 and embedded procedures for commissioning and confidence checks.

How rugged is the unit?

IP65, MIL‑STD‑810H shock/vibration; MIL‑STD‑461G EMC; IACS UR E10/DNV‑CG‑0339 for marine; –32 °C to +55 °C operation.
