JD11 mining intrinsic safety multi parameter detection alarmIntroduction:

The JD11 multi parameter detection alarm is suitable for various underground coal mines, tunnels, petroleum, petrochemical, chemical production equipment areas, as well as municipal, fire, gas, telecommunications, coal, metallurgy, electricity, medicine, food processing and other environments. It has the function of monitoring the concentration value of toxic and harmful gases in the environment.

When the concentration of toxic and harmful gases exceeds the limit, it can automatically emit sound and light alarms. It can be carried by relevant staff, inspectors, ventilators, team leaders, team leaders, engineering technicians, mining cadres, and blasting personnel. The detector has fast response time, stable and reliable performance, low drift, long lifespan, small size, and is easy to carry. It can be tested anytime and anywhere, convenient and efficient.
