Problems solved by technology

When the pressure fluctuates during use, manual adjustment is required to keep the reaction pressure stable, otherwise it will affect the experimental results

Therefore, in experiments that require high reaction pressure stability, the use of manual pressure regulating valves requires the operator to check and adjust the pressure frequently in time, which not only increases the manual workload, but also cannot effectively ensure the stability of the pressure.
