MS104K Portable 4-1 Gas Detector
The MS104K is a high-performance portable gas detector designed for multi-gas monitoring, capable of detecting combustible gases, oxygen, and toxic gases with customizable sensors. Using advanced electrochemical and catalytic combustion technologies (with an optional NDIR infrared sensor), it provides quick, accurate readings. The device features a TFT color LCD for easy operation, with bilingual support (English and Chinese), and includes triple alarm modes (audible, visual, and vibration) for immediate alerts. Constructed from durable PC+TPU anti-static materials and fitted with a stainless steel back clip, it is built to withstand tough industrial environments. With an IP65 rating and Ex ia IIC T4 Ga explosion-proof certification, it ensures safe use in hazardous conditions. The MS104K also stores up to 1000 alarm records, displays trend graphs, and offers a Type-C charging port with a battery life of over 16 hours. Its ergonomic biomimetic owl design combines comfort and aesthetics, making it an ideal choice for industries like petroleum, chemicals, and metallurgy, providing reliable gas safety monitoring and protection.
