OLLI | 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. Ideal Applications Confined space entry Utility gas inspections Wastewater and sewer safety Natural gas distribution Industrial plant safety Pipeline maintenance Oil & gas facilities Hazardous area monitoring Key Features Detects combustible, toxic, and oxygen gases Supports up to 3 interchangeable sensors Certified measuring functions Optional sampling pump Optional pressure measurement Audible, visual, and vibration alarms Up to 50 hours battery life IP67 waterproof and dustproof housing Wireless data transfer Esders Connect digital reporting ATEX, IECEx & INMETRO certified Made in Germany Technical Specifications (U.S. Format) Specification Value Detectable Gases CH₄, C₃H₈, O₂, CO, CO₂, H₂S Methane/Propane 0–1,000 ppm LEL Range 0–100% LEL Volume Range 0–100% Vol. CO₂ (Optional) 0–5% Vol. O₂ 0–25% Vol. CO 0–300 ppm H₂S 0–100 ppm Pressure (Optional) 0–14.5 psi (0–1 bar) Display 128 × 64 Backlit LCD Battery Life Up to 50 hours (35 hours with pump) Pump Flow Approx. 20 L/h Protection Rating IP67 Operating Temperature -4°F to 122°F (-20°C to 50°C) Connectivity Wireless & IR Storage 200 MB Dimensions 6.7 × 3.1 × 1.7 in (170 × 80 × 43 mm) (pump version) Weight 0.77 lb (350 g)
