Multi-Gas Detector

The OLLI Multi-Gas Detector is an ATEX-certified portable gas detector designed for industrial safety, utility operations, confined space entry, and hazardous area monitoring. Supporting up to three interchangeable sensors, it detects combustible gases, toxic gases, oxygen, and optional pressure, providing reliable protection for workers in demanding environments.

Certified to international explosion protection standards, the OLLI measures methane (CH₄), propane (C₃H₈), oxygen (O₂), carbon monoxide (CO), carbon dioxide (CO₂), and hydrogen sulfide (H₂S). Optional internal pump and pressure measurement capabilities make it ideal for confined space inspections, gas utility maintenance, wastewater facilities, pipeline work, and industrial safety applications.
