The alarm concentration of the hydrogen detector is a key factor to ensure industrial safety and stable production environment. Therefore, in order to better ensure safety, the alarm concentration of the hydrogen detector is usually set below the lower limit of the explosion limit. At this time, when the concentration of hydrogen in the environment exceeds the safety threshold, the hydrogen detector will promptly issue an alarm to remind the staff Take necessary protective measures to avoid potential hazards. Do you know the alarm concentration of hydrogen detector ? The following is a brief introduction by yiyuntian electronics:

the alarm concentration of hydrogen detector is not a fixed value, but is set according to specific application scenarios and safety requirements:

1. Alarm Concentration Setting Basis

(1) Explosion limit:

Hydrogen is the 1 flammable and explosive gas, and its explosion limit is within a certain concentration range.Therefore, the alarm concentration of the hydrogen detector should be set outside this range to ensure safety. The explosive concentration range of hydrogen is approximately 4% to 75%(V), but the lower explosive limit (LEL) is often considered to be the key factor in determining the alarm concentration setting.

(2) Safety standards:

Different countries and industries may have their own safety standards that specify maximum allowable concentrations of hydrogen in workplace air. For example, Hygienic Standard for Hydrogen in Workplace Air (GBZ 233-2010) may stipulate that the concentration of hydrogen in the air of the workplace must not exceed a certain value.

(3) Application scenario:

Different application scenarios may have different requirements for the safe concentration of hydrogen. For example, industrial production lines, laboratories, storage warehouses and other occasions, due to the use of hydrogen, storage, leakage risk and other factors are different, therefore, the hydrogen detector needs to set the appropriate alarm concentration according to the actual situation.
