Drager 8323919-Xam 2500 Multi-Gas Detector Ex, O2, H2S, CO or NO2 or SO2 was specially developed for use as personal protection. The 1 to 4 gas detector reliably detects combustible gases and vapors, as well as O₂, CO, H₂S, NO_2, and SO₂. Reliable and fully mature measuring technology, durable sensors, and easy handling ensure a high degree of safety with extremely low operating costs. Fully developed, high-performance Dräger sensors in an extra small format for CO, H₂S, O₂, SO₂and NO₂ gases enable safe use in industry, mining, and refineries. The impressive hydrogen sulfide sensor has a high resolution, so it can reliably measure even very low workplace limits. The non-consumptive and lead-free sensors for oxygen are characterized by an especially long service life of more than 5 years. Dräger´s CO and H₂S sensors also have this long service life expectation, so they contribute to especially low operating costs.
