IECEx and ATEX Certified Portable O2 Gas Detector with 0-30%VOL Range and 2-Year Standby Time

The MiniMeta is a certified single gas detector (IECEx, ATEX, EMC) designed for reliable oxygen measurement in explosive atmospheres. It continuously monitors oxygen (O₂) concentration across a range of 0-30% VOL with a fine resolution of 0.1% VOL, helping users detect both oxygen deficiency (hypoxia) and oxygen enrichment (hyperoxia).

Powered by a 3.6V dry battery (non-rechargeable, replaceable), the device achieves an industry-leading 2-year standby time without requiring battery charging or calibration during normal operation. This makes MiniMeta a low-cost, long-term ownership solution for safety professionals.

The detector uses an electrochemical sensor with diffusion sampling - no pump, no moving parts - ensuring maintenance-free operation. Response time (T90) is 15-30 seconds with accuracy ≤ ±2-5% FS.

A self-test function automatically checks sensor and battery status on power-up, enhancing safety before each use. An optional docking station is available for daily bump tests and calibration.
