粉塵采樣儀可稱環境粉塵濃度測定儀和粉塵濃度氣體樣品采集器。
型號G80457產品簡介：
粉塵采樣器內設有流量傳感器，可對流量進行閉環控制。在采樣過程中，當濾膜阻力增大致使流量下降時，系統將自動調節抽氣泵，保證流量恒定。該儀器抽氣負壓高、流量大，可以采集全塵與可吸入塵。該儀器具有定時控制、時間顯示、電池電壓監視等功能，使用方便、可靠。本儀器廣泛適用于冶金、礦山、石化、建材等行業的環?？諝赓|量監測。是空氣中各種塵埃理想的捕集器。

Can be called environmental instrument for measuring dust concentration and dust concentration gas sample collector dust sampling instrument.
Introduction model G80457 products:
Dust sampler equipped with flow sensor, which can be used to control flow. In the sampling process, when the membrane resistance increases the flow decreased, the system will automatically regulate the pump, ensure the constant flow. The suction pressure is high, large flow, can collect the dust and respirable dust. The instrument has the timing control, time display, battery voltage monitoring function, easy to use, reliable. Environmental air quality monitoring the instrument widely used in metallurgy, mining, petrochemical, building materials and other industries. Is in a variety of air dust ideal trap.
