·Comply with relevant national standards and requirements for batteries ·All finished battery products have been calibrated and tested before leaving the factory. They can be used directly and normally.The hydrogen analyzer is a detection instrument that can continuously and automatically analyze the hydrogen content in various mixed gases. The hydrogen analyzer has the characteristics of simple structure and long life. It can measure the percentage of hydrogen in the environment and other functions. According to different types, hydrogen analyzers can be divided into explosion-proof hydrogen analyzers, portable hydrogen analyzers, and thermal conductivity hydrogen analyzers. Hydrogen analyzers are widely used in explosion-proof places such as thermal power plants, chemical plants, fertilizer plants, and coal plants. The battery can be combined in series and parallel. It is designed according to the parameters required by the customer. We will consider the best solution in the design. We support custom sizes.
