Explosion proof digital dust analyzer visual particle monitoring trend instrument

Explosion proof digital dust analyzer visual particle monitoring trend instrumentLD-8FThe explosion-proof digital dust detector is obtainedIIClass andIIIA fast dust analyzer with explosion-proof certification, which adopts the principle of light scattering and is equipped with a calibrated optical stability self calibration device. It can eliminate the influence of temperature and humidity drift and achieve rapid determination of the concentration of particles of different sizes in the air.Explosion proof digital dust analyzer visual particle monitoring trend instrumentSuitable for occupational health law enforcement personnel to detect dust concentration in the air of workplaces, and can also be used for non coal mines, tunnels, occupational health supervision, petrochemical industry, grain processing, transportation and storageConduct explosion-proof dust concentration testing at the production site of the enterprise.
