Products Description：
MHNV Handheld Explosion-proof Gas Detector is a non-contact intrinsically safe gas leak detector based on Optical Gas Imaging(OGI).It is primarily used for detecting VOCS gas leaks.
MHNV Handheld Explosion-proof Gas Detector portable device can quickly scan gas pipelines and equipment without interrupting operations,and locate gas leak points in real-time and intuitively through thermal imaging.It allows rapid detection at a safe distance,ensuring the safety of operators and facilitating quick repairs to avoid danger and loss.MHNV product features infrared temperature measurement ,EXic IIc T4 Gc explosion-proof certification,and IP54 protecting rating.
MHNV Handheld Explosion-proof Gas Detector can be used in petroleum and petrochemical enterprises, offshore oil platforms, power stations, refineries,refineries, biogas plants, hazardous chemical parking lots,hazardous chemical storage tank areas,natural gas stations, natural gas storage facilities, natural gas pipelines and chemical/chemical industries, etc.
