Ion Science ARA-X4 Multi-Gas Detector

The Ion Science ARA-X4 is a compact, intrinsically safe portable multi-gas detector that simultaneously monitors four atmospheric hazards: combustible gas (LEL), oxygen (O2), carbon monoxide (CO), and hydrogen sulfide (H2S). Available with catalytic bead (CAT) or infrared (IR) LEL sensing and standard or long-life oxygen sensors, the ARA-X4 warms up in about one minute, self-tests on startup, and runs on a rechargeable lithium-ion pack. ARA-X Manager software handles configuration, calibration records, firmware updates, and data log export, and the optional ARA DOCK4 automates bump testing and calibration for up to four units at once.

APPLICATIONS

Confined Space Entry: Pre-entry and continuous atmospheric monitoring in vaults, manholes, tanks, and vessels.

Utility and Municipal Work: Sewer, water, and gas distribution maintenance.

Environmental and Remediation Sites: Landfill, brownfield, and drilling operations where LEL and H2S are hazards.

Oil, Gas, and Petrochemical: Turnaround work, hot work permitting, and area monitoring.

Emergency Response: First-in atmospheric assessment alongside a PID for VOCs.

WHY THE ARA-X4

• Four gases in one intrinsically safe, pocket-sized instrument

• Choice of catalytic bead or infrared LEL sensor for methane-rich or inert atmospheres

• Long-life (LF) oxygen sensor option reduces replacement frequency

• One-minute warm-up with automatic self-test

• User-replaceable sensors with no factory return needed for routine swaps

• ARA DOCK4 docking station for one-button bump test, calibration, and data transfer
