CROWCON TETRA 4 Gas Detectors (O2, LEL, H2s, CO) 4 Gases BX616
Small size and light weight. Simple operation with just 1 button. Low battery voltage alert. Gas measurement: O2, CO, H2S and CH4 methane fuel. Dimension and weight: 120 × 68 × 30mm, about 220g. Ingress protection: IP66.
BX616 is a bonded gas detector that measures four (4) main gases, which result in most industrial accidents, to protect disasters caused by O2 deficiency, toxic gas poisoning and combustible gas explosion . It continuously measures four gases O2, CO, H2S, and fuel gas (CH4), and displays their concentrations. Once the hazard occurs, the alarm (visual, audible and vibrating) is also activated.



Certifications: IP65, IP67, IECEx and CSA.
