Product Description
SFC25 respirable constant current dust sampler is a common instrument for collecting the gas
in atmospheric environment and workshop site .
It is widely used in metallurgy, chemical industry, building materials, electric power, mining,etc
The instrument has high performance suction pump, automatic time control circuit, flow control circuit,
automatic feedback constant current circuit, undervoltage protection alarm circuit, safety power
supply.
It is also equipped with a variety of dust preliminary traps ,among which , thewholedust trap is used
for measurement of the total dust concentration and the impect trap for measurement of respirable
dust concentration can seperate the harmful respirable dust from norespirable dust ,collecting both
the two dust sanples.The separation efficiency reaches the Internationally recognized “BMRC”curve
standard .It is a kind of more reliable
and practicalpreceding stagedust separation device.
The machine casing is moistureproof, dustproof and antistatic . It has the advantages of no
pulsating flow, negative pressure, big load capacity, automatic timing sampling, safe and reliable,
durable, easy to carry and
suitable for field use .The main technical parameters has reached or approached international
advanced level.
Main features:
1.Micro processing technology, humanized design, liquid crystal display
2.With buit-in high performence nimh battery it can work continuously for a long time
