MUNI Pu'an New Generation Portable Composite Gas Detector MP420
Date: 2022-06-29Read: 1
MUNI is a new generation portable composite gas detector from Mengpu'an, which can accurately detect four gases: combustible gas (LEL), oxygen (O2), carbon monoxide (CO), and hydrogen sulfide (H2S). It can also detect gases such as HCN and SO2 for different application industries; The energy consumption control technology of Mengpu'an can ensure continuous operation for more than 24 hours after a single charge; MUNI is designed to be lightweight, compact, and easy to carry, with a protection level of up to IP68, making it suitable for any harsh working environment; Durable and sturdy design, easy operation and maintenance, and extremely low operating costs. It can be widely applied in industries such as metallurgy, petroleum and petrochemical, chemical, fire protection, telecommunications, municipal, sewage treatment, and shipping.
