Dust-detection Helmet / Helmet

Dust-detection Helmet
Dust-detection Helmet

Dust concentration under the mine often exceeds the standard, easy to cause explosion and disaster. The Dust-detection Helmet can tell exactly the concentration of dust in air, and give the worker alarming signal by light color. White light color is for safe concentration; yellow for little higher than standard, and red for danger point. The worker can take proper actions to get away from danger. It works easily, exactly, safely and directly.
