Introduction
BH-90M series Gas Detector stands out in the industry with its good performance and reliable technology. It adopts industrial-grade sensors and micro-control technology, has fast response, high-precision measurement capabilities, and excellent stability and repeatability, and is praised as the industry's advanced level. The designers drew design inspiration from the pebbles and designed the main body of the product to be as rounded as possible, avoiding the appearance of edges and corners, making it small and durable in appearance. The shell is made of high-strength engineering plastics and covered with composite anti-slip rubber, which not only has high strength and good feel, but also has the characteristics of waterproof, dustproof and explosion-proof.
Its advanced large-scale integrated circuit technology is in line with international intelligent technology standards. Gas detection by natural diffusion with very good sensitivity and repeatability. It is very convenient to use and maintain, which greatly meets the needs of high reliability of equipment for industrial site safety monitoring. The shell is also made of high-strength engineering plastics, covered with composite anti-slip rubber, which ensures the strength and feel of the product, and has multiple protection functions such as waterproof, dustproof and explosion-proof.
Scope of application
BH-90M series Gas Detector has been widely used in petroleum, chemical, environmental protection, metallurgy, refining, gas transmission and distribution, biochemical medicine, agriculture and other industries. Its application in explosion-proof, toxic gas leakage rescue, underground pipelines, mines, metallurgy, power plants, chemical industry, tunnels, tunnels and other places effectively prevents the occurrence of poisoning accidents and ensures the life safety of staff and the integrity of production equipment.
