Hydrogen Dispenser Calibration Device

In today’s era of rapid development in new energy, hydrogen is emerging as a significant force in the future energy sector due to its clean and efficient properties. According to data from TrendBank, as of August 2024, China has built 493 hydrogen refueling stations, the highest number in the world.

As a critical component of the hydrogen energy industry, the safety, stability, and reliable operation of hydrogen refueling stations are of great public concern. Among these, the product quality and measurement accuracy of high-pressure hydrogen dispensers are crucial factors that cannot be overlooked in the commercialization process.

In February 2024, the Shaanxi Provincial Market Supervision Administration issued JJG (Shaanxi) 010-2024, the "Verification Regulations for Compressed Hydrogen Dispensers," which was officially implemented in August. According to national metrology regulations, all measuring devices used for trade settlements must undergo mandatory verification, typically within a cycle of no more than six months. Accurate measurement not only protects consumer rights but is also a key factor in promoting the healthy development of the hydrogen energy industry.
