In air, its output is a low‑current signal typical of galvanic cells, roughly 40–55 microamps at about 21% O2, providing a direct electrical signal to the instrument for stable, repeatable readings. The sensor is specified for an operating range of 5°C to 45°C and a life of about 32 months in air at 25°C and 1 atm; for gas streams containing more than 0.5% CO2, the XLT‑11‑24‑4 variant is recommended to maintain performance. This model is part of Analytical Industries’ Made‑in‑USA GPR family and is distributed by suppliers like Instrumart as a genuine Analytical Industries replacement sensor, underscoring its role as a standard, reputable component in professional oxygen‑monitoring setups. \u003c\/p\u003e\u003c\/div\u003e","brand":"Analytical","offers":[{"title":"New","offer_id":46278741000426,"sku":null,"price":1160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-077.png?v=1788727428","url":"https:\/\/gtghardware.com\/products\/analytical-industries-gpr-11-32-4-oxygen-sensor","provider":"GTG Hardware","version":"1.0","type":"link"}
